Is Spinosaurus the biggest dinosaur? How many teeth does it have?
Answer 1:

The sauropod dinosaurs are actually the biggest. The largest complete dinosaur we know of was Brachiosaurus, which has 52 teeth. It was about as long as two large school buses and as tall as a four-story building! Some other sauropod dinosaurs may be a little bigger but we do not know for sure because we do not have a full skeleton to measure. But blue whales are still bigger than any of the dinosaurs
