Sarcosuchus (/ ˌ s ɑːr k oʊ ˈ s uː k ə s /; lit. ' flesh crocodile ') is an extinct genus of crocodyliform and distant relative of living crocodilians that lived during the Early Cretaceous, from the late Hauterivian to the early Albian, 133 to 112 million years ago of what is now Africa and South America.
Deinosuchus (/ ˌ d aɪ n ə ˈ sj uː k ə s /) is an extinct genus of alligatoroid crocodilian, related to modern alligators and caimans, that lived 82 to 73 million years ago (Ma), during the late Cretaceous period.
The only order-level taxon that is currently considered valid is Crocodilia in its present definition. Prehistoric crocodiles are represented by many taxa, but since few major groups of the ancient forms are distinguishable, a conclusion on how to define new order-level clades is not yet possible. (Benson & Clark, 1988).
Crocodilians range in size from the dwarf caimans and African dwarf crocodiles, which reach 1–1.5 m (3 ft 3 in – 4 ft 11 in), to the saltwater crocodile and Nile crocodile, which reach 6 m (20 ft) and weigh up to 1,000 kg (2,200 lb), [38] [46] though some prehistoric species such as the late Cretaceous Deinosuchus were even larger at up to ...
Kaprosuchus is known from a nearly complete skull 507 mm in length in which the lower jaw measured 603 mm long, total length is estimated to be around 2.42–3.77 m (7 ft 11 in – 12 ft 4 in) long. [3]
The discovery of a prehistoric crocodile fossil in Peru from around 7 million years ago has given paleontologists more clues as to how modern crocodiles, all freshwater creatures in the Andean ...
Estemmenosuchus (meaning "crowned crocodile" in Greek) is an extinct genus of large, early omnivorous therapsid.It is believed and interpreted to have lived during the middle part of the Middle Permian around 267 million years ago.
Protosuchus (from Greek: protos, "first" and Greek: souchos, "crocodile") [1] is an extinct genus of carnivorous crocodyliform from the Early Jurassic. It is among the earliest animals that resemble crocodilians. Protosuchus was about 1 metre (3.3 ft) in length and about 40 kilograms (88 lb) in weight.
