Czatkobatrachus is an extinct genus of Early Triassic (Olenekian) salientian amphibians. It was first described in 1998 based on fossils found in the 1 quarry in Poland. It is, with Triadobatrachus, one of the two oldest known lissamphibians. More precisely, it is a member of Salientia; it is related to, but outside Anura, the taxon that includes all extant frogs.

The earliest salientian yet discovered is Triadobatrachus massinoti, known from a single fossil specimen found in Madagascar. It dates back to the Early Triassic, about 250 million years ago. It had many frog-like features, but had 14 presacral vertebrae, while modern frogs have nine or 10. Previous fossil amphibians had many more presacral vertebrae than this and T. massinoti provides a missing link between salamanders and frogs.

Triadobatrachus is an extinct genus of salientian frog-like amphibians, including only one known species, Triadobatrachus massinoti. It is the oldest member of the frog lineage known, and an excellent example of a transitional fossil. It lived during the Early Triassic about 250 million years ago, in what is now Madagascar. Life restoration by Pavel Riha Triadobatrachus was long, and still retained many primitive characteristics, such as possessing at least 26 vertebrae, where modern frogs have only four to nine.

Very few fossils of early salientians have been found, which makes defining the characteristics of the group and their taxonomic relationships difficult. The arrangement of pectoral elements and the number of vertebrae are some guides, but the degree of vertebral articulation and the arrangement of the bones in the leg have not been found to be reliable indicators. The early proto-frogs developed from temnospondylid ancestors in which some of the elements of their vertebrae remained separate. The structure of the salientian pelvis and hind limb was probably developed for swimming rather than jumping.
