Best Answer

Current best estimates are that there was a large meteor that landed in Chixculub in Mexico, and the energy from this impact sent up a dust cloud that changed the climate for a period. Much too cold. This was about 65 million years ago.

Many other things survived this catastrophe - particularly ocean dwelling, and things that 'hibernated'. The ocean scavengers probably had a good time as well.

Survivors include the birds, the Tuatara, and the mammal ancestors.
