Dinosaur Unit Study
This extinct species continues to fascinate us millions of years later
They roamed the earth 65 million years ago, being the size of small buildings, teeth sharp enough to go through concrete, and running at speeds that could be considered fast enough for some freeways, Dinosaurs are quite an interesting creature to study and attempt to understand. Presently, scientists are still attempting to figure out how these huge creatures once roamed the earth, what their daily routines were like, and how come these animals are extinct?
The term dinosaur (terrible lizard) was coined by the English anatomist Sir Richard Owen in 1842.
There are three geologic time periods that dinosaurs lived: Triassic, Jurassic, and Cretaceous
The largest complete dinosaur we know of was Brachiosaurus ("arm lizard"); it reached 23 m in length and 12 m in height (about the length of two large school buses and the height of a four-story building
There are approximately 700 different types of dinosaurs.

2) How old do dinosaurs generally get?
