Typical detail of a steel truss, which is considered as a revolute joint Historical detail of a steel truss with an actual revolute joint A truss is an assembly of beams or other elements that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as nodes.

The leaf edges may be curved backwards or revolute. Flower colour is one of the most variable characteristics. The main colour of the perianth may be red, orange or pink or more rarely yellow or cream. There is often a transition of colour along the length of the perianth leading to commonly seen red-yellow or red-cream combinations.

In some cases, but not all, there exist analytical solutions to inverse kinematic problems. One such example is for a 6-DoF robot (for example, 6 revolute joints) moving in 3D space (with 3 position degrees of freedom, and 3 rotational degrees of freedom). If the degrees of freedom of the robot exceeds the degrees of freedom of the end-effector, for example with a 7 DoF robot with 7 revolute joints, then there exist infinitely many solutions to the IK problem, and an analytical solution does not exist. Further extending this example, it is possible to fix one joint and analytically solve for the other joints, but perhaps a better solution is offered by numerical methods (next section), which can instead optimize a solution given additional preferences (costs in an optimization problem).

Quercus delgadoana was determined as a new species because, unlike Q. eugeniifolia with fruit with annual maturation, this species has fruit with biennial maturation. In addition, this new species can be distinguished from other similar species such as Q. laurina and Q. affinis because it has more secondary veins, a revolute blade margin, and an adaxial leaf surface without stellate trichomes.

Plantarum Sinensium. J. de Botanique 13: 253-260. It is a small to medium-sized evergreen tree growing to 7-40 m tall, often less at tree line.

B. ser. Abietinae was first published in 1856, in Carl Meissner's chapter on the Proteaceae in A. P. de Candolle's Prodromus systematis naturalis regni vegetabilis. It was one of four series into which the subgenus Eubanksia was divided. These four series were defined in terms of leaf characters, with series Abietinae containing the species with entire or shortly denticulate leaves with revolute margins.

Original illustration of Helichrysum pumilum (left) alongside H.milliganii (right) by Joseph Dalton Hooker. Flower head Helichrysum pumilum grows as a low tufted, perennial herb reaching around 10 cm tall. Leaves are linear to spathulate in shape, 15-50mm long and 1-5mm wide with revolute margins. They are grouped in a rosette and arise from the base of the plant.

The posterior angle is acute. The outer lip is thin, showing the external sculpture within. The inner lip is slightly curved, decidedly revolute, adnate to the base, provided with a strong, obliquo fold at its insertion. The parietal wall is covered with a thick callus, which connects the insertion of the inner lip with the posterior angle of the aperture.

The leaves are aromatic, simple, opposite (or fascicled), elliptic to obovate or spatulate, 5–10 mm long, with revolute margins. The flowerheads are axillary, sessile, few-flowered, with a strigose calyx; the corolla is whitish, about 2 mm long, four-lobed, and with four stamens. The fragrant foliage and tiny white flowers are highly attractive to pollinators, in particular the Atala butterfly.

Prismatic joint seen in 2-dimensional form. Only linear motion is possible. In contrast to a revolute joint the axis is prevented from rotating (this can be accomplished by giving the axis a prismatic shape which is not visible here). A prismatic joint provides a linear sliding movement between two bodies, and is often called a slider, as in the slider-crank linkage.

Individuals of this species are oak trees that grow up to tall and have trunks in diameter. These oaks are often among the tallest trees in the wet montane forests. They are characterized by their thick branchlets and lance-shaped leaves with revolute margins. They bear acorns as fruits and have pistillate flowers on a short stalk, which have 1 or 2 distal flowers.

The outer lip is thin, showing the external sculpture within. The inner lip is almost straight, oblique, somewhat revolute, and provided with a strong fold a little anterior to its insertion. The parietal wall is covered with a thick callus. P.

For each joint of the kinematic chain, an origin point q and an axis of action are selected for the zero configuration, using the coordinate frame of the base. In the case of a prismatic joint, the axis of action v is the vector along which the joint extends; in the case of a revolute joint, the axis of action ω the vector normal to the rotation.

This is supported by observations that plants growing in shady subalpine pockets—where the need for sunlight may offset the need for a tough exterior—tend to have flatter or broader leaves with recurved rather than revolute margins. Little is known about fungal interactions with O. revolutus, however there is clear evidence of dieback in Tasmania’s Central Highlands that may be attributed to a Phytophthora species.

The leaves are ovate, long, with bluntly serrated edges and a distinct point at the end; the leaf margin is revolute, the very edge being curled under, a diagnostic character which distinguishes it from all other alders. The leaves turn yellow in the autumn before falling. The male flowers are dangling reddish catkins long in early spring. Female flowers occur in clusters of (3) 4–6 (8).

Cistus grancanariae was first described in 2008 by Águedo Marrero, Rafael Almeida and Carlos Ríos. One of the group of white-flowered species of Cistus, it was previously mistaken for Cistus monspeliensis, common in Gran Canaria. The leaves of the two species are different: C. monspeliensis has narrower leaves, more rolled under at the edges (more revolute), with upper surfaces that are green, sticky (viscous), and without stellate hairs.

Its leaves are alternate or opposite or rarely in whorls of three or four. They are linear and 3–20 mm long by 1–2 mm wide with revolute margins and stiff, occasionally gland-tipped hairs which give a toothed appearance. The midrib on lower surface is often glandular/hairy and the leaves are sometimes sessile. The flowers are solitary (rarely paired) on peduncles which are 3–10 mm long.

Most SRJs are designed with an offset housing, allowing for higher compressive loads in a smaller space. Alternatively, the joint can be assembled backwards for higher tensile load capability but less range of motion. An alternative to the SRJ is the universal joint, which consists of two revolute joints. By using spherical rolling joints instead of universal, designers can reduce the number of joints to achieve the same result.

As with the other varieties of B. spinulosa (Hairpin Banksia), B. spinulosa var. spinulosa grows as a multi-stemmed lignotuberous shrub with flower spikes that are all golden or golden with red or purple styles. Its strongly revolute leaf margins distinguish it from the other varieties, and it is further distinguished from B. spinulosa var. collina in having narrower leaves that are serrate only towards the leaf tips.

The flowers are a little more than 1 cm across, with green sepals and petals, and a white lip with purple spots. The sepals are oblong-obtuse, 1 cm long, and 3–4 mm wide; the falcate revolute lateral sepals are slightly shorter and wider than the plicate dorsal sepal. The linear petals are much narrower than the sepals. The deeply trilobate lip is adnate to the column to its apex.

The leaves are10–30 (–40) x 1–2 (–6) mm, linear, linear-oblong or linear-lanceolate, with revolute margins. Leaves have a blue-grey colour and are softly woolly on the under surface, as are the young stems. The upper surface is markedly parallel-veined and grooved, the veins protruding on the under side. This species is known in cultivation, and has gained the Royal Horticultural Society's Award of Garden Merit.

Coupler curves of a crank-rocker four-bar linkage. Simulation done with MeKin2D. Planar four-bar linkages are constructed from four links connected in a loop by four one- degree-of-freedom joints. A joint may be either a revolute, that is a hinged joint, denoted by R, or a prismatic, as sliding joint, denoted by P. A link connected to ground by a hinged joint is usually called a crank.

Crank slider mechanisms with 0 and 1.25 eccentricity. A slider-crank linkage is a four-bar linkage with three revolute joints and one prismatic, or sliding, joint. The rotation of the crank drives the linear movement the slider, or the expansion of gases against a sliding piston in a cylinder can drive the rotation of the crank. There are two types of slider-cranks: in-line and offset.

They are trees and bushes, hermaphrodites. The leaves are alternate, entire, glabrous or pubescent, pinnatinervias, with longitudinal grooves. Simple, alternate, petiole 0.9 to 2.2 cm in length canalicular limbo 11 to 28 cm long and 5 to 11 cm wide, with 16-28 secondary veins; base acute decurrent and revolute, entire, apex elliptically shaped, green dark, and very oblique secondary veins visible on the underside. terminal buds whitish.

The lanceolate leaves of Ozothamnus ledifolius are evergreen, neat and glossy above and downy underneath, with a revolute margin, and produce a peppery fragrance in summer due to the leaf exudates that include a series of flavonoid aglycones and mostly consist of mixture of terpenoids. In resinous material of leaf exudate four sesquiterpenes, a diterpenediol and two pentacyclic triterpene acids are present. The phenolic portion of exudate encompasses three phenylethyl esters.

The cap margin is usually buff to light brown–roughly the same color as the spines and lighter in color than the center. It becomes rolled inward (revolute) and often wavy in maturity. The spines on the underside of the cap are a few millimeters long and cylindrical down to their sharp tips. White to light brown when young, they later become covered with a white spore mass and then turn an ashy gray.

Cistus munbyi has narrow linear leaves with a single prominent vein, generally long by wide, with edges that are turned down (revolute). The upper surfaces of the leaves are smooth, the lower surfaces have a dense covering of short stellate hairs. It has white flowers. C. munbyi resembles C. clusii, but the flower-bearing branches are longer and the flower stalks (peduncles) and sepals are covered with white hairs, making them appear silky ("sericeus").

The leaf margins are recurved, sometimes to the extent of being near-revolute. Flowers appear between July and February (mid winter to late summer) in its native range. These have perianths which are red at the base and yellow at the top, or alternatively red/white, apricot/white or occasionally all yellow. The styles are green at the base, becoming pink or red towards the tip, with the tip itself being green.

Consistent with this higher diversity is a reduction in ecological dominance by a handful of taxa. O. revolutus’ namesake revolute leaf margins are very likely an adaption to the harsh growing conditions of its range, presumably adding structural integrity to leaves often exposed to frost, sleet and driving wind, as well as very high UV levels. The margins would also reduce air movement across the stomata, presumably protecting the plant from desiccation.

The leaf margins are revolute and finely toothed towards the leaf tip, which ends in a short mucronate point. The leaf midrib is prominent. Leaves growing on the primary stem are small and scale-like, while the basal leaves on the secondary stems are also very small. It occurs in short grassland in open woodland, occasionally in forests, heaths, sand dunes and chalk grassland, and on grassy rock ledges and tree trunks.

The lid is similar to that found in terrestrial traps, although slightly smaller (up to 6 cm long by 5 cm wide) and often bearing a revolute margin. Other parts of upper pitchers are similar to their lower counterparts. Nepenthes bokorensis has a racemose inflorescence measuring up to 100 cm in length. It bears up to 80 flowers borne on one-flowered pedicels (≤9 mm long), or rarely two-flowered partial peduncles.

Kalmia polifolia can grow to be two feet tall. Its leaves are arranged oppositely upon its branch and grow to be an inch to an inch and a half in length and tend to be waxy with an entire and revolute margin. Below each leaf base there are ridges, where it appears as though a part of the leaf is curled around the circumference of the stem. This is especially noticeable lower on the plant.

The Stanford arm, on display at Stanford University The Stanford arm is an industrial robot with six degrees of freedom, designed at Stanford University by Victor Scheinman in 1969Stanford Arm history. The Stanford arm is a serial manipulator whose kinematic chain consists of two revolute joints at the base, a prismatic joint, and a spherical joint. Because it includes several kinematic pairs, it is often used as an educational example in robot kinematics.

Hyacinthoides cedretorum differs from other species of Hyacinthoides in the strongly revolute (curved backwards) form of the tepals, with the stamens being attached to the tepals only at their bases; in other species, the stamens are fused to the tepals along much of their length, and the tepals form a bell-like shape. The anthers and pollen are typically violet-blue, but populations from the High Atlas mountains have creamy-yellow pollen.

Cistus heterophyllus grows up to tall, forming an erect, much-branched shrub. Its leaves are elliptical to lanceolate in shape, usually long, the upper surfaces being dark green with stellate and simple hairs, and the lower surfaces whitish with a coating of short hairs. The leaf margins are slightly turned under (revolute) and the veins are much more obvious on the underside. The leaves are of two kinds: the upper are without stalks (petioles), the lower have short stalks.

Cistus inflatus is a slightly spreading shrub, up to tall. It leaves are green, oblong in shape, usually long by wide, with turned under (revolute) margins, variably hairy, with long simple and stellate hairs on both sides. The leaves are unstalked (sessile) and, at least near the base, have three veins. The flowers are arranged in cymes with one to five individual flowers, each across with five white petals with narrowed yellow bases, and five sepals.

Orites revolutus , also known as narrow-leaf orites, is a Tasmanian endemic plant species in the family Proteaceae. Scottish botanist Robert Brown formally described the species in Transactions of the Linnean Society of London in 1810 from a specimen collected at Lake St Clair. Abundant in alpine and subalpine heath, it is a small to medium shrub tall, with relatively small, blunt leaves with strongly revolute margins. The white flowers grow on terminal spikes during summer.

Orites revolutus grows as a spreading bush or an erect, woody shrub, usually in height. Branching is dense and the leaves are alternate up the stem. Leaf shape is narrow and fairly blunt at the apex, 7–20 mm long, 1-1.5 mm wide, with tightly revolute margins and a hairy surface on the underside. Flowering occurs in early to mid-summer with the sour-scented flowers arising on terminal spikes to twice the length of the leaves.

Hoya bilobata was originally collected on the Philippine island of Mindanao, and sent to Dr. Rudolph Schlechter, a German economic botanist, who first described it in 1906. H. bilobata is one of the many small leaved and flowered Hoyas belonging to Schlechter's section Acanthostemma. Acanthostemma species are characterised as having flowers with hairy corollas, coronas with outer lobes ending in two inward turning lateral extensions, and petal lobes that are completely revolute. A study by Wanntorp et al.

Bertya opponens is a shrub or small tree growing to 4 m high, and has a dense covering of whitish to brownintertwined hairs. The leaves are mostly opposite, and are 10–50 mm long and 5–25 mm wide, with glands at the apex. The leaves have hairy upper surfaces, which become rough with age, and lower surfaces which are densely covered with intertwined white hairs, and having a prominent midrib. The leaf margins are recurved to revolute.

The seeds are pale to medium brown, ovate, oval, elliptic, elliptical at 5 mm wide by 2 mm (0.2 by 0.08 in). The margin is revolute towards the hilar side. In other words, the edge of the seed is rolled backward from the margins to the undersurface on the scarred side of the seed from a stalk connecting an ovule or a seed with the placenta. The testa, the often thick or hard outer coat of a seed, is rough.

Thus, the relative movement between points in two connected links is considered to result from the kinematic pair that joins them. Kinematic pairs, or joints, are considered to provide ideal constraints between two links, such as the constraint of a single point for pure rotation, or the constraint of a line for pure sliding, as well as pure rolling without slipping and point contact with slipping. A mechanism is modeled as an assembly of rigid links and kinematic pairs. Revolute pair cutaway view.

Male flower Bertya gummifera is a sticky shrub, growing from 1-2 m high. The young growth is covered long whitish hairs, which sometimes persist on the stems, but most of the plant loses these and becomes rough and hairless with age. The rough-surfaced leaves are 10-50 mm long and about 2 mm wide, and have margins which are rolled downwards from the upper surface (revolute). The flowers (with and without stalks) are crowded, and have 5-8 bracts.

321 kinematic structure is a design method for robotic arms (serial manipulators), invented by Donald L. Pieper and used in most commercially produced robotic arms. The inverse kinematics of serial manipulators with six revolute joints, and with three consecutive joints intersecting, can be solved in closed form, i.e. a set of equations can be written that give the joint positions required to place the end of the arm in a particular position and orientation.D. L. Pieper, The kinematics of manipulators under computer control.

Mesonychids have often been reconstructed as resembling wolves, albeit superficially, but they would have appeared very different in life. With a short lower spine stiffened by revolute joints, they would have run with stiff backs like modern ungulates rather than bounding or loping with flexible spines like modern Carnivorans. While later mesonychids evolved a suite of limb adaptations for running similar to those in both wolves and deer, their legs remained comparatively thick. They would have resembled no group of living animals.

Inverse kinematics specifies the end-effector location and computes the associated joint angles. For serial manipulators this requires solution of a set of polynomials obtained from the kinematics equations and yields multiple configurations for the chain. The case of a general 6R serial manipulator (a serial chain with six revolute joints) yields sixteen different inverse kinematics solutions, which are solutions of a sixteenth degree polynomial. For parallel manipulators, the specification of the end-effector location simplifies the kinematics equations, which yields formulas for the joint parameters.

Cistus libanotis is a prostrate or less often erect shrub, up to tall. It leaves are dark green, long and thin in shape, usually long by wide and with turned under (revolute) margins. The upper surfaces of the leaves have only a few stellate hairs, particularly on the margins and the nerves; the lower surfaces have a conspicuous nerve and two dense bands of short stellate hairs. The flowers are arranged in cymes or whorls, the top group forming an umbel of three or four flowers.

Cistus clusii is a much branched shrub, up to tall. Its leaves are narrowly linear in shape, usually long by wide, with edges that are turned under (revolute), green on the upper side and densely covered with short hairs on the lower side, producing a whitish appearance. The flowers are arranged in an umbel-like cymes with up to 12 individual flowers, each across with five white petals and three sepals, long. The flower stalks (peduncles and pedicels) and the sepals are covered with long white hairs.

The product of exponentials (POE) method is a robotics convention for mapping the links of a spatial kinematic chain. It is an alternative to Denavit–Hartenberg parameterization. While the latter method uses the minimal number of parameters to represent joint motions, the former method has a number of advantages: uniform treatment of prismatic and revolute joints, definition of only two reference frames, and an easy geometric interpretation from the use of screw axes for each joint. The POE method was introduced by Roger W. Brockett in 1984.

Or it can be constructed as a two cranks with the slider acting as the coupler, known as an inverted slider-crank. # Two revolute joints and two prismatic joints: The double slider is a PRRP linkage. This linkage is constructed by connecting two sliders with a coupler link. If the directions of movement of the two sliders are perpendicular then the trajectories of the points in the coupler are ellipses and the linkage is known as an elliptical trammel, or the Trammel of Archimedes.

This culminated in the 1969 publication of The International Register of Dahlia Names by the Royal Horticultural Society which became the central registering authority. This system depended primarily on the visibility of the central disc, whether it was open centred or whether only ray florets were apparent centrally (double bloom). The double bloom cultivars were then subdivided according to the way in which they were folded along their longitudinal axis, flat, involute (curled inwards) or revolute (curling backwards). If the end of the ray floret was split, they were considered fimbriated.

An example of a simple open chain is a serial robot manipulator. These robotic systems are constructed from a series of links connected by six one degree-of-freedom revolute or prismatic joints, so the system has six degrees of freedom. An example of a simple closed chain is the RSSR spatial four-bar linkage. The sum of the freedom of these joints is eight, so the mobility of the linkage is two, where one of the degrees of freedom is the rotation of the coupler around the line joining the two S joints.

The surface where the vertebrae join is flat rather than revolute, which would have made the series more flexible than that of terrestrial relatives. For the four preserved sacral vertebrae, the transverse processes of S1 are smaller than those of L8, and form a robust sacroiliac joint with the hip. For the spinous processes, those of S1–S3 are fused. Metapophyses jut straight up from each lamina near the joint, progressively getting smaller with each vertebra. The holotype preserves 26 ribs, though it is thought to have had 32 in life.

Under Brown's taxonomic arrangement, B. nutans was placed in subgenus Banksia verae, the "true banksias", because its inflorescence is a typical banksia flower spike. Banksia verae was renamed Eubanksia by Stephan Endlicher in 1847. Carl Meissner demoted Eubanksia to sectional rank in his 1856 classification, and divided it into four series, with B. nutans placed in series Abietinae because of its entire leaves with revolute margins. When George Bentham published his 1870 arrangement in Flora Australiensis, he discarded Meissner's series, placing all the species with hooked styles together in a section that he named Oncostylis.

The lower surfaces are protected by the strongly revolute shape of the leaf, the leaf margins curling around underneath almost to the mid-vein. The trichomes (leaf hairs) run along the mid-vein and the margins, further protecting the surface where the stomates are located, thus minimising water loss. Cladistic analysis suggests this species and its relatives in the series Abietinae developed long narrow leaves with inrolled margins as they invaded drier climates in Australia's southwest, having evolved from ancestors with broad leaves. The inflorescences are highly attractive to insects.

Around 1972, Scheinman was asked by MIT's Marvin Minsky to design a more compact arm. Minsky had funding from DARPA for a new robot and had visions of using it for remotely supervised surgery. Scheinman spent the summer at the MIT AI lab, designing a new arm that became the MIT Arm, completing the design back at Stanford. Like the Stanford arm, new arm featured a wrist with all axes intersecting, allowing a closed form arm solution, but now all the axes were revolute, unlike the Stanford arm which had a prismatic joint.

Its lineage would therefore extend to an era, some 20 mya, when tropical species covered the southern part of the continent. The habit of this shrub is low-lying and sprawling, at 0.1 metres tall, or erect to a height of 2 metres. It has spiky branchlets, small leaves in an alternate arrangement, and small flowers that are clustered on relatively long stalks. The leaves are entire, or with a toothed margin, are linear in outline or broader at the base, may have hairs, veins that branch from the central axis, and are rolled upon themselves in a revolute manner.

This is a body that pivots on a fulcrum. Because the velocity of a point farther from the pivot is greater than the velocity of a point near the pivot, forces applied far from the pivot are amplified near the pivot by the associated decrease in speed. If a is the distance from the pivot to the point where the input force is applied and b is the distance to the point where the output force is applied, then a/b is the mechanical advantage of the lever. The fulcrum of a lever is modeled as a hinged or revolute joint.

Simple linkages are capable of producing complicated motion. The configuration of a system of rigid links connected by ideal joints is defined by a set of configuration parameters, such as the angles around a revolute joint and the slides along prismatic joints measured between adjacent links. The geometric constraints of the linkage allow calculation of all of the configuration parameters in terms of a minimum set, which are the input parameters. The number of input parameters is called the mobility, or degree of freedom, of the linkage system. A system of n rigid bodies moving in space has 6n degrees of freedom measured relative to a fixed frame.

The name Orites revoluta (referring to the tightly revolute leaf margins) was first published by the Linnaean Society of London in March 1810 in the paper On the natural order of plants called Proteaceae by Robert Brown. However, the orthographic variant Orites revolutus is used just as widely and is often reported to be the more correct species name. Brown's paper also established the genus Orites, named for the Greek oreites, meaning “a mountaineer” (denoting the montane distribution of the genus). The paper included dozens of pages of taxonomic revisions for the family Proteaceae, although much of this important work is not officially attributed to Brown.

Annales des Sciences Naturelles; Botanique, sér. 2 4: 348-349 description in Latin, commentary in French and neighboring Jordan,Mouterde, Paul 1966. Nouvelle Flore du Liban et de la Syrie 1: 365 whose national tree it is. Quercus ithaburensis is a small to medium-sized semi-evergreen to tardily deciduous tree growing to a maximum height of around 50 feet (15 m) with a rounded crown and often with a gnarled trunk and branches. The leaves are 1.6-3.5 in (4–9 cm) long and 0.8-2.0 in (2–5 cm) wide, oval in shape, with 7 to 10 pairs of either teeth (most common) or shallow lobes (rare) along a revolute margin.

The product of exponentials method uses only two frames of reference: the base frame S and the tool frame T. Constructing the Denavit–Hartenberg parameters for a robot requires the careful selection of tool frames in order to enable particular cancellations, such that the twists can be represented by four parameters instead of six. In the product of exponentials method, the joint twists can be constructed directly without considering adjacent joints in the chain. This makes the joint twists easier to construct, and easier to process by computer. In addition, revolute and prismatic joints are treated uniformly in the POE method, while they are treated separately when using the Denavit–Hartenberg parameters.

It has grey, fissured bark, and hairy stems, putting on new growth in summer. Alternately arranged along the stems, the dark green, wedge-shaped leaves are 4 to 12 cm (1.8–4.2 in) long and 0.7 to 2 cm (0.3–0.8 in) wide with serrated margins. Leaf dimensions vary in different populations: plants from the western and coastal parts of its range have shorter and broader leaves—4 to 6 cm by 1 to 2 cm, while inland plants from around Mt Charles and Mt Ragged have longer and narrower leaves and less revolute leaf margins. Flowering takes place mainly from March to August, though occasional flower spikes may appear till December.

Pakicetus attocki Interpretations of pakicetid habitat and locomotion behaviour varies considerably: In 2001, it was concluded by Thiwissen et al. that "pakicetids were terrestrial mammals, no more amphibious than a tapir." According to them, none of the aquatic adaptations found in the oldest obligate aquatic cetaceans, basilosaurids and dorudontids, are present in pakicetids. Pakicetid cervical vertebrae are longer than in late Eocene whales, the thoracic vertebrae increase in size from the neck backwards, and the lumbar and caudal vertebrae are longer than in modern cetaceans (but still shorter than in some extinct cetaceans with undulating spines.) Motion in the spine of pakicetids was further reduced by the revolute zygapophyses (processes between the vertebrae) like in stiff-backed runners such as mesonychians.

The seed of Pachypodium baronii is pale brown with margin medium brown when fresh. It is ovate to elliptic at 6 mm (0.236-inch) to 7 mm (0.256-inch) by 3 mm (0.118-inch) to 3.8 mm (0.150-inch). It is rounded at the apex, obtuse at the base, and has a margin that is revolute towards the hilar side. The testa is smooth. The coma is straw-colored and at 1 cm (0.39-inch) to 1.5 cm (0.59-inch) long. The embryo is whitish at 5 mm (0.197-inch) by 6 mm (0.236-inch) long. The cotyledons are ovate and 1.14 to 1.2 times as long as it is wide at 3 mm (0.118-inch) to 4 mm (0.158-inch) long by 2.5 mm (0.98-inch) to 3.5 mm (0.138-inch) wide. They are rounded at the apex and cordate at the base with a rootlet 0.6 to 0.8 times as long as the cotyledons at 2 mm (0.079-inch) to long by 1.0 mm (0.039-inch) to 1.8 mm (0.071-inch) wide.
