A few nice extinct animal images I found:

Okay, the lack of animals disappointed me, but the fact that they had an Okapi made my day. Until very recently (2006), they were believed extinct so YES!

Lions used to be one of the widest-spread animals around the world. They used to live in the New World until they went extinct with most of the rest of the megafauna.
