Modern crocodilians, a subgroup of Neosuchia, emerged during the Late Cretaceous. [8] Crocodylomorph diversity was severely reduced by the end-Cretaceous extinction event . [ 9 ] The last group of terrestrially adapted crocodylomorphs was the Sebecidae , a group of large predatory notosuchians which persisted in South America until the middle ...
Alternatively, interpretation based on the fossil-bearing rocks along the Red Deer River in Alberta, Canada, supports the gradual extinction of non-avian dinosaurs; during the last 10 million years of the Cretaceous layers there, the number of dinosaur species seems to have decreased from about 45 to approximately 12. Other scientists have made ...
The first fossil materials were collected by an expedition of South African Museum in April 1963 led by Alfred W. Crompton. [1] The materials were collected from the Lower Jurassic Red Bed Formation (= Upper Elliot Formation) of the Stormberg, so that as soon as they found out that the fossils belongs to a new crocodilian species, they named the species Orthosuchus Stormbergi in a paper ...
Modern crocodilians also have a deltopectoral crest, but it is positioned laterally and anchors to muscles that pull the arms up to the sides, not forward. The muscle thought to have facilitated forward movement in Stratiotosuchus is called the deltoideus clavicularis ; it is also present in modern crocodilians, which use it for high walking.
[30] Deinosuchus is generally thought to have employed hunting tactics similar to those of modern crocodilians, ambushing dinosaurs and other terrestrial animals at the water's edge and then submerging them until they drowned. [31] A 2014 study suggested that it would have been able to perform a "death roll", like modern crocodiles. [32]
A crocodile-like creature bit the neck of a flying dinosaur some 76 million years ago – and scientists have proof.. Archaeologists found the fossilized neck bone of the young pterosaur in Canada ...
The discovery of Confractosuchus was announced by the Australian Age of Dinosaurs museum on 11 February 2022, and was published in the journal Gondwana Research. [4] It is the second extinct eusuchian crocodyliform genus discovered from the Winton Formation, after Isisfordia that was discovered during the mid-1990s and named in 2006. [5] [6]
More than 100 million years ago, an ancestor of today’s alligators and crocodiles wandered through present-day South Korea on its hind limbs, scientists announced June 11 in the journal ...
