For over 200 million years, mammals have inhabited the Earth. In this epic evolutionary journey, mammals lived with—and even ate—dinosaurs, swam in the ocean, flew in the air, and became the fastest land animals of all time!

This Summer, NHMLA brings you our temporary exhibition, Extreme Mammals: Odd Features. Unusual Creatures. Explore the evolutionary standouts and oddities from the largest to smallest, the speediest to sloth-like, and features such as over-sized claws, fangs, snouts, and horns. Get ready to marvel at the bizarre, amazing, and extraordinary world of extinct and living mammals.
