I am rather surprised at all the attention the find mentioned in this article is getting. Some would think that these mammals caused the downfall of the dinosaurs, but the fossil record suggests a very different scenario. There is no evidence of possum-to-coyote–size mammals for the 70-odd million years that the dinosaurs ruled the planet. The only mammals able to remain uneaten were no larger than a rat, almost too small to be noticed.
