Hi sopioalya, I have honestly no idea. There were three periods (Triassic, Jurassic, Cretaceous) in which dinosaurs lived during the Mesozoic era (which lasted 185 million years). In each of these periods the species of dinosaurs were different; some species would die out, others evolved to be a bit different.
So there would have been a lot! but I can’t tell you how many.

I’m guessing. No idea. Maybe it was 3,279.
I Googled it. http://pubs.usgs.gov/gip/dinosaurs/types.html
It’s about 1000. I was amazingly close and am going to give myself a prize.
