He argued that feeding its great bulk would have led it to consume the entire last generation of dinosaurs before they could even hatch, leading to their extinction. [20] He also suggested that mammals may have driven the dinosaurs extinct by eating all of their eggs. [7] 1928. L. Müller proposed that volcanic eruptions drove the dinosaurs ...
[38] [39] Modern crocodilians can live as scavengers and survive for months without food, and their young are small, grow slowly, and feed largely on invertebrates and dead organisms for their first few years. These characteristics have been linked to crocodilian survival at the end of the Cretaceous.
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 ...
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 ...
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.
But dinosaur brain cases more closely resemble those of modern-day reptiles like crocodiles, Caspar said. For animals like crocodiles, brain matter occupies only 30% to 50% of the brain cavity.
Non-crocodilian reptiles have 3-chambered hearts, which are less efficient because they let the two flows mix and thus send some de-oxygenated blood out to the body instead of to the lungs. Modern crocodilians' hearts are 4-chambered, but are smaller relative to body size and run at lower pressure than those of modern birds and mammals.
The researchers identified a series of 9-inch-long prints as belonging to an ancient crocodylomorph, a group that includes living crocodilians (alligators, crocodiles, and other similarly-sized ...
