About 160 years ago, a fossil was found in New Jersey that scientists were able to use to describe the sea turtle Atlantochelys mortoni. The fossil fragments are a perfect match and now give scientists more information about one of the largest sea turtles that ever lived. The original fossil was found in 1849 and was identified to be part of the sea turtles broken arm bone. Since then its been sitting in the Academy of Natural Sciences of Drexel University — until recently, when amateur fossil paleontologist Gregory Harpel presented a fossil he discovered on an embankment in Monmouth County. According to BBC News, Harpel thought it was a rock at first, but then noticed marks he believed to be shark bites and knew he had stumbled upon something more significant.
