the Pleistocene Megafauna 'saber tooth tiger 'mamoth ' there is a kind of sloth but i forget what its called and some very small dinos that lived
I think they became extinct at the end of the Mesozoic era
The ice age began at the end of the Jurassic period, a theory of why the dinosaurs became extinct. <33
Like many ice age species, it became extinct at the end of the Pleistocene Epoch 16,500 years ago.
They became extinct in the mass extinction at the end of the Ordovician Period.
Hundreds of species died out at the end of the last ice age but it was mainly the largest animals that suffered, Mammoths, Mastodons, Dire Wolves, Artodus, European Lions, Cave Bears, European Hyenas etc.
The primary prey of saber toothed tigers were big game animals. They would have hunted deer, bison, camelops (an extinct species of North American camel), and even mammoths and giant ground sloths. At the end of the ice age, many of these large prey animals that the saber toothed cat depended on died out, and the saber toothed cat became extinct.
Ammonites went extinct at the end of the Cretaceous Period.
No. If you count birds as dinosaurs, they still exist. If you don't, dinosaurs became extinct at the end of the Cretaceous, not the beginning.
If I read this correctly you call them extinct.
Pterosaurs declined during the Late Cretaceous due to competition with early birds. The last pterosaurs became extinct in the End Cretaceous Mass Extinction, which was caused by an asteroid impact in the Gulf of Mexico.
Non avian dinosaurs became extinct 65.5 million years ago, at the end of the Cretaceous. However, birds are considered dinosaurs. Because birds still exist, dinosaurs are not completely extinct.
