What do you know about Pangaea?

Did you know that Pangaea started 225 million years ago. In my science text book for seventh grade i learned something really amazing. They have images of pangaea drifting apart. I noticed that it drifts apart each 45 million years. The weird thing is that the Mesozoic Era the period of the dinosaurs began 245 million years ago and lasted 180 years. The second drift is when dinosaurs roamed the earth, the meteor that ended dinosaurs hit earth 65 million years ago which hit the coast of New Mexico. Which the thrid drift is when the northern cracked and left eastern part of Asia and Europe. Hope this helps!!
