Re: "Dinosaurs Died Within Hours After Asteroid Hit Earth..."
You know, I always thought that there might be
something to the idea that the KT impact(s) were so
catastrophic that the large animals were wiped out
To quote the Jeff Goldblum JP character "life will find
a way". Had there been significant number of dinosaur
survivors of those first weeks, would not at least some
of them had "found a way" like the surviving critters
did? Their size, and warm-bloodedness, appear to have
been the decisive factors in their extinction.
