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 .
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 reasons Paraceratherium and its relatives became extinct after surviving for about 11 million years are unknown, but it is unlikely that there was a single cause. Theories include that their large size was related to the now outdated concept of inadaptive evolution , climate change , vegetational change, and low reproduction rate .
The traditional group "Crocodylia" was replaced by the name Crocodyliformes, defined to include many of the extinct families that the new definition left out. Clark did not initially provide an exact definition for Crocodyliformes; but, in 2001, Paul Sereno and colleagues defined it as the clade including Protosuchus richardsoni and the Nile ...
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 name translates as "terrible crocodile" and is derived from the Greek deinos (δεινός), "terrible", and soukhos ...
Extinct subspecies such as the Javan tiger (Panthera tigris sondaica) [6] are not listed here as the species, in this case Panthera tigris, is still extant. The IUCN Redlist classification for each species serves as a citation, and the superscripted "IUCN" by the date is a link to that species' page.
Phytosaurs are generally regarded as the most basal group of Crurotarsi, a clade of archosaurs that includes crocodilians and their extinct relatives. [ 27 ] [ 28 ] [ 29 ] Phytosaurs are often excluded from a clade called Suchia , which usually encompasses all other crurotarsans, including aetosaurs , rauisuchians , and crocodylomorphs . [ 29 ]
