Last week, as if to reinforce Dougal Dixon's point, a team led by Harvard Paleontologist Parish Jenkins Jr. announced a rare discovery from northeastern Arizona: a fossil jaw from a tiny, shrewlike, insect-eating mammal that lived during the early Jurassic period, 180 million years ago. At that time the first small mammals evolved from a kind of mammalian reptile. In evolutionary terms, these creatures bided their time, for 115 million years, until the disappearance of dinosaurs and other reptiles allowed them to evolve thousands of different shapes and sizes. Significantly, the Arizona find adds a third major...
...Harvard professor of Biology announced last week that an expedition he led during the summer had found the fossil remains of what is now thought to be the oldest mammal specimen in North America, Farish A. Jenkins Jr., who is also curator of vertebrate paleontology at the Museum of Comparative Zoology, said the jaw-bone fossil belongs to a mouse-sized creature that lived about 180 million years ago. "This is the most exciting find of my career because it stimulates our research of the earliest stages of mammalian history," Jenkins said in announcing the discovery...
