Crocodylomorpha in the modern sense, as defined by Paul Sereno in 2005, is phylogenetically defined as the most inclusive clade containing Crocodylus niloticus (the Nile crocodile), but not Rauisuchus tiradentes, Poposaurus gracilis, Gracilisuchus stipanicicorum, Prestosuchus chiniquensis, or Aetosaurus ferratus.
Deinosuchus had an alligator-like, broad snout, with a slightly bulbous tip. [8] Each premaxilla contained four teeth, with the pair nearest to the tip of the snout being significantly smaller than the other two. [13] Each maxilla (the main tooth-bearing bone in the upper jaw) contained 21 or 22 teeth. [17]
Crocodiles (family Crocodylidae) or true crocodiles are large, semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia.The term “crocodile” is sometimes used more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans (both members of the family Alligatoridae), the gharial and false gharial (both ...
Vulnerable: American crocodile, mugger crocodile, and dwarf crocodile. The main threat to crocodilians worldwide is human activity, including hunting and habitat destruction. Early in the 1970s, more than 2 million wild crocodilian skins had been traded, driving down the majority of crocodilian populations, in some cases almost to extinction.
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 age of the dinosaurs never really ended—it only evolved. Birds (and their more reptilian cousins, the Crocodilia ) are the modern-day legacy of dinosaur’s 165-million-year-long stint on Earth.
A Brazilian scientist has identified fossils of a small crocodile-like reptile that lived during the Triassic Period several million years before the first dinosaurs. The fossils of the predator ...
Sarcosuchus is commonly classified as part of the clade Pholidosauridae, [3] [12] [13] a group of crocodile-like reptiles (Crocodyliformes) related but outside Crocodylia (the clade containing living crocodiles, alligators and gharials). [3] Within this group it is most closely related to the North American genus Terminonaris. [3]
