Brontosaurus- ApatosaurusIt has also been called Brontosaurus (thunder reptile) but the name Apatosaurus was given first. When fully grown it weighed about 30 tons! It therefore spent a great deal of time in the water which helped support its immense weight. They could live to be about 200 years old.

Brachiosaurus• Brachiosaurus was one

of the tallest and largest dinosaurs yet found. It had a long neck, small head, and relatively short, thick tail. Brachiosaurus walked on four legs. Its front legs were longer than its hind legs. These unusual front legs together with its very long neck gave Brachiosaurus a giraffe-like stance and great height, up to 40-50 feet tall.

armored dinosaur, measuring about 25-35 feet long, and 4 feet tall; it weighed roughly 3-4 tons. Its entire top side was heavily protected from carnivores with thick, oval plates embedded (fused) in its leathery skin, 2 rows of spikes along its body, large horns that projected from the back of the head, and a club-like tail.

Shouting out a roar;

Poem from: www.Preschoolfunzone

PowerPoint by Jeanne Guichard

Along came an alligator

Then there were four.

Four enormous dinosaurs

sitting in a tree;

‘Til the wind blew by,

Then there were three.

Three enormous dinosaurs

were taken to the zoo;

‘Til one got away,

Then there were two.

Two enormous dinosaurs were having such fun;

‘Til a volcano blew up,

Then there was one.

One enormous dinosaur,He must of weighed a ton;

‘Til the lakes dried up

Then there were none.
