And, as far as we can tell, it makes sense that mammals took advantages of these opportunities, on land certainly, and even in the sea, in the form of great whales. So the fossil record, I think, shows a fairly dynamic pattern: that following the Cretaceous extinction event, the K-T extinction event, there’s a little lag time for a million or two years, but then we get a tremendous radiation of forms, and those forms become more specialized, they get bigger, so that within about a period of 10 million years, most of the modern groups of mammals have em
