The number of teeth dinosaurs had varied dramatically, depending on the type of dinosaur. Some dinosaurs, like Ornithomimus and Gallimimus, did not have teeth. On the other end of the spectrum, Tyrannosaurus rex had 50 to 60 solid cone-shaped teeth as big as bananas. Hadrosaurs, or duck-billed dinosaurs, had the most teeth: up to 960 cheek teeth! Dinosaur teeth were replaceable. If a dinosaur broke or lost a tooth, another grew in to take the place, behaving much like sharks teeth do today.
The Brachiosaurus was the largest, heaviest, and among the least inteligent dinosaurs found to date. This massive dinosaur could weigh anywhere between a staggering 60 thousand to an unbelievable over 170 thousand pounds (That is roughly 48 mid sized cars). The Brachiosaurus walked on four legs and oddly enough the front legs were actually longer than the back. This is a rare exception in the dinosaur kingdom.
