Cipactli (Classical Nahuatl: Cipactli "crocodile" or "caiman") was the first day of the Aztec divinatory count of 13 X 20 days (the tonalpohualli) and Cipactonal "Sign of Cipactli" was considered to have been the first diviner. [1] In Aztec cosmology, the crocodile symbolized the earth floating in the primeval waters.
In 2003, [5] new fossils of several types of ancient crocodile were found, including one with a flat broad snout reminiscent of a duck's bill, though it has teeth and is obviously crocodilian rather than bird-like. This genus has been named Anatosuchus or "DuckCroc", and it had an upright stance rather than the sprawled legs of modern crocodiles.
Crocodilians are a type of crocodylomorph pseudosuchian, a subset of archosaurs that appeared about 235 million years ago and were the only survivors of the Triassic–Jurassic extinction event. The order includes the true crocodiles (family Crocodylidae), the alligators and caimans (family Alligatoridae ), and the gharial and false gharial ...
Based on the remains, scientists estimate that Barinasuchus would have been around 20-25 feet long and weighed 3,800 lbs.. For reference, the largest species of crocodile today, the saltwater ...
Three extant crocodilian species clockwise from top-left: saltwater crocodile (Crocodylus porosus), American alligator (Alligator mississippiensis), and gharial (Gavialis gangeticus) Crocodilia is an order of mostly large, predatory, semiaquatic reptiles, which includes true crocodiles, the alligators, and caimans; as well as the gharial and ...
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 ...
Crocodilians live almost exclusively in lowland habitiat, and do not appear to live above 1,000 metres (3,300 ft). [115] With a range extending from eastern India to New Guinea and northern Australia, the saltwater crocodile is the widest-spread species. [118] Crocodilians use various types of aquatic habitats.
Crocodylomorpha is a group of pseudosuchian archosaurs that includes the crocodilians and their extinct relatives. They were the only members of Pseudosuchia to survive the end-Triassic extinction . Extinct crocodylomorphs were considerably more ecologically diverse than modern crocodillians.
