It depends what your definition of reptile is. Turtles, Crocodiles are all "living fossils", because they were present in the mesozoic era. (of course not in the same shape or size, but in the same species). Some even say that birds are reptiles. (because latest fossils show us that some dinosaurs had feathers). So to answer your question, turtles, crocodiles and birds are all living reptiles from the mesozoic era.
Hope this helps.
An asteroid impact
Yes, some ancient animals survived the mass extinction primarily by living underground or underwater.
Mesozoic
Avian dinosaurs survived the extinction event of the dinosaurs.
During the Mesozoic extinction, some of the animals that went extinct included non-avian dinosaurs, pterosaurs, marine reptiles like ichthyosaurs and mosasaurs, and various marine invertebrates. This extinction event was primarily caused by a combination of volcanic activity, climate change, and possibly asteroid impact, leading to the demise of many species that could not adapt to the changing environment.
Mass extinction
During the Mesozoic Era, most mammals were small, nocturnal, and likely insectivorous. They were overshadowed by larger reptiles like dinosaurs and did not become the dominant group of animals until after the extinction of the dinosaurs at the end of the Mesozoic.
Two major eras that ended with mass extinctions are the Permian-Triassic extinction event, which marked the end of the Permian period, and the Cretaceous-Paleogene extinction event, which marked the end of the Cretaceous period. These events had profound impacts on life on Earth, leading to the loss of a significant number of species.
