This bestiary briefly introduces some of the species of extinct mammals discussed in various places in this site. Not all the mammals described in the bestiary are Pleistocene extinctions; some of the species described here died out as late as this century. Descriptions include possible causes for why the creature went extinct.

Many illustrations in this bestiary have been drawn for the first time, and represent the first-ever reconstructions of these creatures! You can find first-time reconstructions by looking for species names and illustrations with this symbol  .

You can look for a creature in the bestiary by name (common name, species name, or family name) or by geography (geographic region where it once lived).

enjoy!
