Ornithosuchidae is an extinct family of pseudosuchian archosaurs (distant relatives of modern crocodilians) from the Triassic period. Ornithosuchids were quadrupedal and facultatively bipedal (e.g. like chimpanzees), meaning that they had the ability to walk on two legs for short periods of time.
A single species of Ornithosuchus is recognized, O. woodwardi; O. taylori is a synonym. [3]"Dasygnathus" longidens was in 1877 created by Thomas Huxley for a right maxilla from the Lossiemouth Sandstone found in 1857.

Older definitions of the group Archosauria rely on shared morphological characteristics, such as an antorbital fenestra in the skull, serrated teeth, and an upright stance. Some extinct reptiles, such as proterosuchids and euparkeriids , also possessed these features yet originated prior to the split between the crocodilian and bird lineages.
The name Pseudosuchia was originally given to a group of superficially crocodile-like prehistoric reptiles from the Triassic period, but fell out of use in the late 20th century, especially after the name Crurotarsi was established in 1990 to label the clade (evolutionary grouping) of archosaurs encompassing most reptiles previously identified as pseudosuchians.
The lateral tuber is larger and more concave, like that of ornithosuchids. Apart from these tubera, the proximal part of the tibia is mostly convex. However, a distinct notch is present behind the lateral tuber. This is probably an attachment point for flexor tibialis internus muscle. The distal part is smooth and oval-shaped in cross section ...

[2]The lagomorphs (/ ˈ l æ ɡ ə m ɔː r f /) are the members of the taxonomic order Lagomorpha, of which there are two living families: the Leporidae (rabbits and hares) and the Ochotonidae ().
