375 million year old part fish/part four-legged walker found
From NYTimes, Scientists Call Fish Fossil the 'Missing Link':
Scientists have discovered fossils of a 375 million-year-old fish, a large scaly creature not seen before, that they say is a long-sought "missing link" in the evolution of some fishes from water to a life walking on four limbs on land...
The discovering scientists called the fossils the most compelling examples yet of an animal that was at the cusp of the fish-tetrapod transition. The fish has been named Tiktaalik roseae, at the suggestion of elders of Canada's Nunavut Territory. Tiktaalik (pronounced tic-TAH-lick) means "large shallow water fish."
Dr. Shubin, an evolutionary biologist, let himself go in an interview. "It's a really amazing remarkable intermediate fossil — it's like, holy cow," he enthused.
Michael J. Novacek, [a paleontologist at the American Museum of Natural History in Manhattan]: "...A good fossil cuts through a lot of scientific argument...We've got Archaeopteryx, an early whale that lived on land and now this animal showing the transition from fish to tetrapod. What more do we need from the fossil record to show that the creationists are flatly wrong?"
