Fun Facts: 

Apatosaurus is one of the largest land animals ever to walk on Earth.

Everyone knows the dinosaur “Brontosaurus,” right? Actually, “Brontosaurus” doesn’t
exist, and hasn’t since 1903! Scientists discovered that “Brontosaurus” is actually the same
dinosaur as Apatosaurus, and since Apatosaurus was discovered first, the rules of science
say we have to use that name.

Apatosaurus may have grown very fast – reaching adult size in only 1 or 11 years!

“Gertie the Dinosaur,” an Apatosaurus, was the first ever cartoon character in 1914.


When

When did the dinosaurs live?

The Mesozoic Era (251- 65.5 million years ago) is often referred to as the Age of Reptiles, and encompasses all of the time in which dinosaurs lived.

The Mesozoic Era is separated in to three geological Periods:
1. Triassic Period (251-200 million years ago)
2. Jurassic Period (200-145.5 million years ago)
3. Cretaceous Period (145.5 - 65.5 million years ago)

Apatosaurus lived during the Late Jurassic Period in what is now the western United States, and lived alongside several other dinosaurs, including Camarasaurus, Allosaurus, Stegosaurus, and Ornitholestes.
