The discovery of the remains of a furry, beaver-like animal that lived at the time of dinosaurs has overturned more than a century of scientific thinking about Jurassic mammals.
The find shows that the role of mammals in the time of dinosaurs was greater than previously thought, said Zhe-Xi Luo, curator of vertebrate paleontology at Carnegie Museum of Natural History in Pittsburgh.
The animal is the earliest swimming mammal to have been found and was the most primitive mammal to be preserved with fur, which is important to helping keep a constant body temperature, Luo said.
Until I reached the ripe old age of 40, I pretty much thought that science ruled. You would have had a hard time convincing me that Darwinian Evolution had any major holes in it. I am still not among the "so called" fringe who believe that men walked with dinosaurs 6000 years ago. But now that science believes large mammels lived at the time of the really big reptiles, we might not be arguing about that much.
