Cophylinae is a subfamily of microhylid frogs endemic to Madagascar. It has over 100 species in eight genera. Members of this subfamily range from minute ( 100 mm adult body size), and they are highly ecologically diverse. DNA barcode research has revealed a significant taxonomic gap in this subfamily, and an estimated 70+ candidate species were identified. Many of these have subsequently been described, as well as numerous new discoveries (e.g. 26 species of Stumpffia described in 2017).

Tristichopterids (Tristichopteridae) were a diverse and successful group of fish-like tetrapodomorphs living throughout the Middle and Late Devonian. They first appeared in the Eifelian stage of the Middle Devonian. Within the group sizes ranged from a few tens of centimeters (Tristichopterus) to several meters (Hyneria and Eusthenodon).

Amphibamus is a genus of amphibamid temnospondyl amphibians from the Carboniferous (middle Pennsylvanian) of North America. This animal is considered to have been close to the ancestry of modern amphibians. Its length was about .

Triprion is a genus of frogs (the shovel-headed tree frogs) in the family Hylidae found in the Pacific lowlands of Mexico, the Yucatán Peninsula, and Guatemala. These frogs hide in tree-holes and plug the entrance with their strange-looking, bony heads.

Letheobia is a genus of blind snakes in the family Typhlopidae.

Diadectidae is an extinct family of early tetrapods that lived in what is now North America and Europe during the Late Carboniferous and Early Permian, and in Asia during the Late Permian. They were the first herbivorous tetrapods, and also the first fully terrestrial animals to attain large sizes. Footprints indicate that diadectids walked with an erect posture.

species of amphibian

Pithecopus is a genus of frogs in the subfamily Phyllomedusinae. Species of the genus Pithecopus are found in tropical South America east of the Andes, from southern Venezuela to northern Argentina. Resurrected from the synonymy of Phyllomedusa in 2016, it corresponds to the former Phyllomedusa hypochondrialis group. Its sister group is Callimedusa.

Tritylodontidae ("three-knob teeth", named after the shape of their cheek teeth) is an extinct family of small to medium-sized, highly specialized mammal-like cynodonts, with several mammalian traits including erect limbs, endothermy, and some details of the skeleton. They were the last-known family of the non-mammaliaform synapsids, persisting into the Early Cretaceous.

species of reptile

Dysganus (dis-GANN-us) (meaning "rough enamel") is a dubious genus of ceratopsian dinosaur from the Campanian stage of the Late Cretaceous. The fossil teeth referred to Dysganus were first collected by Charles Sternberg from the Judith River Formation of Montana and later described by Edward Drinker Cope. All of the species are now seen as dubious ceratopsians, though referred material from tyrannosaurids and hadrosaurids were found in New Mexico.

Colosteidae is a family of stegocephalians (stem-group tetrapods) that lived in the Carboniferous period. They possessed a variety of characteristics from different tetrapod or stem-tetrapod groups, which made them historically difficult to classify. They are now considered to be part of a lineage intermediate between the earliest Devonian terrestrial vertebrates (such as Ichthyostega), and the different groups ancestral to all modern tetrapods, such as temnospondyls (probably ancestral to modern amphibians) and reptiliomorphs (ancestral to amniotes such as mammals, reptiles, and birds).

Baphetidae is an extinct family of stem-tetrapods. Baphetids were large labyrinthodont predators of the Late Carboniferous period (Namurian through Westphalian) of Europe. Fragmentary remains from the Early Carboniferous of Canada have been tentatively assigned to the group. The phylogenetic relationships of baphetids is uncertain; while many studies have placed the group as a close relative of Amniota, other analyses have found Baphetidae to be a more basal clade of early stem tetrapods. Baphetids were among the first of the Carboniferous fossil tetrapods to be found and were originally descr

Dendrobatinae is the main subfamily of frogs in the family Dendrobatidae, the poison dart frogs of Central and South America, found from Nicaragua to the Amazon basin in Brazil.
