The Day The Mesozoic Died

           It explains a lot in which the dinosaurs died, because of a giant meteor shower, and they got burnt into a crispy potato chip. Now lets say if they were baked with the heat of a meteor shower, than how would that impact the dinosaurs in the water very far away from where the meteors struck. Also if there was a giant water and sediment movement then wouldn't it affect where the dead dinosaur bones were laid? I understood that there was a giant meteor and it crashed into the earth making a giant tsunami, and later a death of all the dinosaurs.
