The Habitats

What is a habitat? The areas or biomes of our planet are homes to different plants and animals. The landscape, temperature, amount of rainfall, and many other factors make each habitat unique.

Click on the gallery pictures below to see the biomes of North America (Tundra, Boreal Forest, Alpine/Montane, Eastern Deciduous Forest, Grassland, Desert) and one from Central America (Tropical Rainforest) featured in Habitat Hall. What similarities do you see in the habitats? What differences?

The Dinosaurs

Habitat Hall features complete, mounted articulated skeleton casts of two of the great Jurassic dinosaurs, Allosaurus and Stegosaurus; a Tyrannosaurus rex skull cast; and several casts of smaller dinosaur skulls and bones. Click on the pictures below to get up close!


Allosaurus is a meat-eating dinosaur from the Jurassic period (200 million years ago). Allosaurus means “different lizard,” because its backbones (vertebrae) were unlike anything paleontologists had seen at the time. Allosaurus had long claws and sharp teeth to help it catch and kill its prey.  Ours is a copy of a dinosaur found at the Cleveland-Lloyd Dinosaur Quarry in Utah.

Stegosaurus is a plant-eating dinosaur from the Jurassic period (200 million years ago). Its long tail was covered in spikes, which helped protect it from predators like Allosaurus. Stegosaurus means “roof-lizard,” because scientists used to think that the bony plates along its back laid down flat, like shingles on a roof. Today we know the plates stood upright and were used for display or may even helped keep Stegosaurus cool. (Copy of dinosaur found at Cleveland-Lloyd Dinosaur Quarry in Utah)

Tyrannosaurus rex

Tyrannosaurus rex is a meat-eating dinosaur from the Cretaceous period (68 million years ago). T rex’s name means “tyrant lizard king,” and it was one of the largest predators to ever walk on land. (Copy of dinosaur on display at the Carnegie Museum of Natural History)
