Most likely, the end of the last ice age.
climate change
yes
the climate change during the shifting of the plates that was causing the making of Pangea
climate is caused by the interplay of many factors.
Mass extinctions are caused by rapid, global changes. Usually these are changes in climate. Without the right temperatures and precipitation, plants that animals depend on die out, which wipes out the animals. Examples include the Permian-Triassic Extinction, where volcanoes in what is now Siberia caused intense global warming, wiping out over 90% of species, and the K-T Extinction, where an asteroid impact suddenly blocked sunlight for months or years, killing off the dinosaurs and many other organisms.
human
Scientists are not sure what caused the extinction of the woolly mammoths, but they have a few theories. These include climate change at the end of the Ice Age, human induced diseases, and human overhunting. It could also be any combination of the above.
Extinction, climate change, decrease or increase in animals, loss of food.
There was a minor extinction event at the end of the Jurassic period. It was probably caused by global climate change. Dinosaurs like Allosaurus, Ceratosaurus, Camarasaurus, and Stegosaurus couldn't adapt to the change in temperature, so they all died out. The Cretaceous period then came after the Jurassic period had ended.
andrewsarchus might have gone extinct during the central Asian extinction caused by the formation of the Himalaya Mountains 40 million tears ago or because of Habitat loss maybe Global warming and Climate change
Mass extinction could occur due to climate change, an asteroid impact and even a volcanic eruption.
