So... which kind of dinosaur was the champion of the ancient world? Could Usain Bolt win against that one?

it could be the Gallimimus, which could run as fast as 70 miles per hour, definitely faster then Usain Bolt. the t-rex could only run about 15 mph, but since its huge size, it still could eat you

Who would win?Carcharodontosaurus,Tyrannosaurus Rex ,Spinosaurus,Giganotosaurus,Sinraptor,Allosaurus, or Saurophaganax?

I think it would be between Carcharodonasaurus, T. rex and Giganotosaurus, maybe Saurophagnax too. T. rex is the main unique one, the others are allosaurs and giganotosaurs, and mostly similar, although Carchar and Giga are bigger then the other two. Spino isn't built for hunting dinosaurs, its a fisher, so it has no chance, Allosaurus and Sinraptor are likely too small to last very long, although they might be agile enough to win but its doubtful.

How fast were dinosaurs?

Google Classroom

Trying to estimate the speed of animals dead for more than 65 million years is difficult, but some generalizations are rather clear from the shape and size of dinosaur skeletons. For example, immense sauropods, such as Apatosaurus and Diplodocus with their massive bodies and columnar leg structure, were probably not fast runners other than in short bursts. Conversely, lighter and relatively long-limbed theropods, such as Velociraptor and ornithomimids (or "ostrich-mimic dinosaurs) were probably capable of running at high, sustained speeds.

If a dinosaur's bone was fractured, what would most likely happen to it? Would the bone heal, or would it have to spend it's life hobbling around?

  The area around the bone would have been swollen, but it would most likely heal. This kind of happened to the allosaurus "Big Al"

Video transcript

When you say how fast dinosaurs were it depends on which dinosaur you're talking about. Just like, you know, mammals today go all the way from you know something like an armadillo or a sloth which, you know, we can outrun on a bad day to animals like cheetahs which can run in excess of a hundred kilometers an hour. Some of the most complete studies have been based on biomechanical models which people can actually construct models of these things using engineering programs and then run them in computers. And it's a lot of work to do this, so there haven't been a lot of animals which have been done, one animal which has been done is Tyrannosaurus Rex, and people have been able calculate from it that Tyrannosaurus Rex could run at a top speed of about eighteen miles an hour.
