All dinosaurs did not die. They are even still all around us, you see them every day, in fact.
I ate some slow smoked dinosaur for lunch just now we commonly call it chicken. Anyone who is in NYS should go to the natural history museum next to central park they have the best dinosaurs to birds lineage display I have seen. Better than the Smithsonian in D.C. I went to both in November 19 so they should still be exhibited.
