Fossil Fragment Found by Student Could Hint Origins of Vertebrates
A 1.25 inch fossil fragment found by David Corley, 19, of Leeds, at a Birmingham quarry may identify a new species and shed light on the origin of bone and vertebrates. UAB geologist George Brockman dates the Devonian limestone at 435 million years old and calls the specimen a primitive chordate with a spinal cord but no backbone. If confirmed, the find could position Corley in the Smithsonian Institute as the finder and inspire naming of the fossil after him.
