Extinct crocodylomorphs were considerably more ecologically diverse than modern crocodillians. The earliest and most primitive crocodylomorphs are represented by " sphenosuchians ", a paraphyletic assemblage containing small-bodied, slender forms with elongated limbs that walked upright, which represents the ancestral morphology of Crocodylomorpha.
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.
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 ...
The American crocodile (Crocodylus acutus) is a species of crocodilian found in the Neotropics.It is the most widespread of the four extant species of crocodiles from the Americas, with populations present from South Florida, the Caribbean islands of Cuba, Jamaica, Hispaniola, [4] and the coasts of Mexico to as far south as Peru, Ecuador, Colombia, and Venezuela.
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.
Crocodiles with teeth the size of bananas were apparently a nightmare that actually existed during the Late Cretaceous period. A pair of researchers with the University of Iowa decided to re ...
