The Day The Mesozoic Died Video Recollection

In science class over the period of about two days, we've been watching a 34-minute video about the day the Mesozoic died. It talked about these scientists who investigate this asteroids crater. When it hit it displaced a lot of laters of ground material and left a big "dent" in the earth. When it hit a lot of dinosaurs were "broiled" alive within an hour of impact. This caused big fires. These fires launched dangerous substances into the air and completely whipped out the dinosaurs ability to breathe as well as obliterated the sun! Without the sun the plants couldn't complete their photosynthesis processes and everything dependent of that was lost.
