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 , 130 to 112 million years ago of what is now Africa and South America .
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.
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.
Based on the findings, Barinasuchus likely lived around 42 million years ago, going extinct around 11.8 million years ago. During this period, sebecids were spread across the South American ...
Why did they go extinct? Well, the Molossus dogs weren’t really as necessary anymore and, let’s face it, these dogs took a LOT to raise, train, and feed. Their numbers started to decline ...
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 ...
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 ...
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 ]
