Summary- Scientist now believe that dinosaurs are taller because they had thick cartilage in their joints. Dinosaur bones are different from the bones of mammals. Dinosaur bones have rounded ends and no obvious way to connect to one another. The bones without the cartilage are 4 to 10 percent smaller. Aligators' and ostrichs' bones have 6 to 10 percent cartilage.
Opinion- I wonder how they didn't know this before. I hope that now that they now this that they will be able to make better perdictions. I think that they are ........um.......cool. My cousin was obsessed with dinosaurs when he was little. I hope they get it right this time.
