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??
