A new study finds that megatooth sharks’ warm-blood adaptation and giant size may have played a role in their extinction. Scientists find new clue in what led to megalodon’s demise Skip to ...
Marine mammals likely constituted a big part of megalodon's menu, so with it gone, they were free to thrive. Observations indicate that in the years since the mega-shark's extinction, baleen ...
Famously, in the Cretaceous–Paleogene extinction event, the non-avian dinosaurs and most other giant reptiles were eliminated. However, the earlier mass extinctions were more global and not so selective for megafauna; i.e., many species of other types, including plants, marine invertebrates [78] and plankton, went

The Triassic-Jurassic extinction completed the transition from the Palaeozoic evolutionary fauna to the Modern evolutionary fauna, [20] a change that began in the aftermath of the end-Guadalupian extinction [21] and continued following the Permian-Triassic extinction event (PTME). [22] Between 23% and 34.1% of marine genera went extinct.
