The features it shares with modern frogs include a forward-sloping ilium, the fusion of the frontal and parietal bones into a single structure known as the frontoparietal, and a lower jaw bone with no teeth. [11] Czatkobatrachus is another proto-frog with some characteristics similar to Triadobatrachus. It is from the early Triassic in Poland ...
Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs is an extension of the male cloaca
The third distal carpus is fused with the remaining carpal bones. The adductor longus muscle is present in the neobatrachians, but absent in the archaeobatrachians and some mesobatrachians. It is believed to have differentiated from pectineus muscle , and this differentiation has not occurred in the primitive frogs.
The Arthroleptidae / ˌ ɑːr θ r oʊ ˈ l ɛ p t ɪ d iː / are a family of frogs found in sub-Saharan Africa.This group includes African treefrogs in the genus Leptopelis along with the terrestrial breeding squeakers Arthroleptis, and several genera restricted to the Guinean forests of central and west Africa, such as the hairy frog (Trichobatrachus).
Hyalinobatrachium have a bulbous liver covered by white pigment, a transparent parietal peritoneum, and lack a humeral spine in adult males.The bones are white in living animals.

Taxonomy [ edit ] Caligophryne was described in 2023 alongside Neblinaphryne , another ancient frog genus thought to belong to its own family that is also endemic to the Neblina massif; both are the first frog taxa described simultaneously as a new species, genus, and family since the purple frog in 2003.
