I did research on a dinosaur named Diplodocus. Its name means
“double beam”. A Diplodocus liked to eat plants. It weighed 11.7 U.S.
tons. It was 90 feet long. Paleontologists have found bones from my
dinosaur in Colorado, Montana, Utah, and Wyoming. A paleontologist
studies dinosaurs and digs up fossils. I also learned that it was from the
Jurassic period, about 156 million to 145 million years ago. Its
nostrils were at the top of its head. The first Diplodocus fossil was
found by Earl Douglass and Samuel W.Williston in 1878.
