It's a common misconception that all of the "well known dinosaur types" were around at the same time, when many of them were separated by millions of years. You commonly see depictions of T-rex fighting Stegasaurus, Velociraptors jumping on a Brachiosaurus... tens of millions of years between them!

Also most of the dinosaurs in "Jurassic Park" are not Jurassic at all. It should be called "Cretaceous Park"... in fact the Brachiosaurs are the only ones in the first film I can think of that are actually Jurassic.

I guess it should be called "Mesozoic Park" most accurately. Not very catchy though
