They lived a really long time
ago. All the dinosaurs surveyed said they wouldn't leave the Jurassic
period if you paid them, and that you would have to dig up their bones to
bring them into the 21 century ! |

The apatosaurus was their best
friend, and by the way, handy to have on your basketball team. (although the
T-Rex was better on the fast break) |
| They prefer their salad fresh,
without any dressing ( a herbivore, they eat plants not meat). |
| They wouldn't tell us what
those 17 bony plates on their backs are for, but with all that laying around
that they do, we think they act like radiators and help cool 'em off. |
| It's a good idea to stay away
from their tail when they're in a bad mood; otherwise they'll show what
those pointy things are used for. |
| They were about 20 feet long
and weighed about 10 tons. |
| Their brain weighed about 2 1/2
oz, about the size of a walnut. (their embarrassed to talk about this
fact) Paleontologists used to think that Stegosaurus had two
brains. Now they think the second brain is really only a blob of
nerves cells that may have controlled the hind legs. |
| You pronounce their name 'STEG-uh-sawr-us' |
| They are the Colorado state
fossil. |
| The first Stegosaurus fossil was found in 1876 by M. P.
Felch. Paleontologist Othniel C. Marsh gave Stegosaurus their name in
1877. |
| Stegosaurus means 'Covered
Lizard' or 'Roof Lizard'. |
| Different species of Stegosaurus
had different numbers of tail spikes. Stegosaurus ungulatis had 8
spikes and Stegosaurus stenops had 4 spikes.
