Mesozoic extinction
The true importance of Pelorocephalus is that it was a "chigutisaur," one of the few amphibian families to survive the end-Triassic extinction and persist into the Jurassic and Cretaceous periods; its later Mesozoic descendants grew to impressively crocodile-like proportions.Additional resources. The Cretaceous period was the last and longest segment of the Mesozoic era. It lasted approximately 79 million years, from the minor extinction event that closed the Jurassic ...

Global ecomorphological restructuring of dominant marine reptiles prior to the K/Pg mass extinction 2022-01-01 | Preprint DOI: 10.1101/2021.12.30.474572According to a UK Natural History Museum article, it may have taken up to 10 million years for the Earth to recover and repopulate after the Permian mass extinction. During the Triassic, large conifer forests covered much of the Supercontinent of Pangea, and the most common land vertebrate was a small, herbivorous, and mammal-like reptile ...
Ichthyosaurs thrived during much of the Mesozoic era; based on fossil evidence, they first appeared around 250 million years ago ... Even older fossils shows they were around 250 million years ago, just two million years after the Permian mass extinction. This early diversity suggests an even earlier origin, possibly late Permian.Many species that lived in the tropics also went extinct in the model, but it predicts that high-latitude species, especially those with high oxygen demands, were nearly completely wiped out. This illustration shows the percentage of marine animals that went extinct at the end of the Permian era by latitude, from the model (black line) and from …The Paleozoic Era ended with the largest extinction event of the Phanerozoic Eon, the Permian–Triassic extinction event. The effects of this catastrophe were so devastating that it took life on land 30 million years into the Mesozoic Era to recover. Recovery of life in the sea may have been much faster.Unlike Cenozoic mammals, mammals of the Mesozoic were uniformly small. TRUE. T/F.

Jurassic Period, second of three periods of the Mesozoic Era. Extending from 201.3 million to 145 million years ago, the Jurassic was a time of global change in the continents, oceanographic patterns, and biological systems. On land, dinosaurs and flying pterosaurs dominated, and birds made their first appearance.The exact cause of their extinction, along with other ancient creatures, is still debated, but it's often associated with the mass extinction event at the end of the Mesozoic Era, coinciding with ...The Cenozoic era began 65 million years ago after the mass extinction of the dinosaurs at the end of the Mesozoic era.

Mesozoic reptiles. The close of the Permian saw the greatest mass extinction known (see the Permian-Triassic extinction event), an event prolonged by the combination of two or more distinct extinction pulses.The Cretaceous-Tertiary Boundary (or K/T Boundary) Extinction. The Cretaceous-Tertiary boundary is associated with one of the most investigated mass extinction events. The age of the K/T boundary is currently estimated to be about 66 million years based on absolute dating methods. It is has been well investigated partly because it is the ...
