Dinosaurs

By: Bridget DeLaurentis & Katie Colletti

Do you know where Dinosaurs came from??? The word Dinosaur comes from the Greek

language and it means “terrible lizard”. The First Dinosaurs evolved in the middle to

late Triassic period. Dinosaurs lived on earth until 65 million years

ago when mass extinction occurred. The only dinosaurs we know about are the

ones that left fossil remains. A person that studies dinosaurs in known as a

Palentologist.

Tyrannosaurus Rex The abbreviation for Tyrannosaurus Rex is T-

Rex. The T-Rex lived in the area of the Earth that

now makes up western north America. T-Rex walked on two legs. The T-Rex had very small arms, but they were

extremley powerful. They lived around 66 million years ago. The skull of a T-Rex measured up to five feet

long!

Is this what you pictured a T-Rex to look like??

Spinosaurus The name Spinosaurus means “spine

lizard” The first fossils of the Spinosaurus were

found in Egypt around 1910. The Spinosaurus was larger than the T-

Rex. The Spinosaurus had a long thin skull. The Spinosaurus had a spine that grew

over five feet tall!

Can you imagine having a spine five feet tall??

Carnotaurus Carnotaurus means “meat eating bull”. Carnotaurus lived around 66 million

years ago. Carnotaurus lived in an area of south

America. Unlike other dinosaurs, Carnoraurus’

eyes faced forward. Carnotaurus had very small arms and

fingers that did not move.

Can you find the eyes that face forward??

Velociraptor Velociraptor means “swift seizer”. Velociraptor lived around 73 million

years ago. The Velociraptors were around the size

of a turkey. A fully grown one was 6 feet in length and weighted up to 33 pounds.

The first Velociraptor fossil was found in the Mongolian Gobi Desert in 1922.

Can you believe this only weighs 33 pounds??
