Prehistoric mammals are various groups of mammals that lived over 10,000 years ago. The earliest mammals arose from mammal-like reptiles in the middle of the Jurassic period and remained subdued by the reign of the dinosaurs.
The lineages of many varieties continued through the Tertiary period where they reached incredible dinosaur-like sizes. Most became extinct in the last ice age.
Popular prehistoric mammals include:
- Basilosaurus
- Brontotherium
- Eohippus

- Irish elk
- Mammoths
