Fitting two halves
What at first appeared to be an oddly placed stone, found in 2012 by amateur fossil hunter Gregory Harpel, turned out to be half of a fossilized sea turtle bone. The most amazing part: The other half was found more than 160 years ago. Here, David Parris (shown here), curator of natural history at the New Jersey State Museum, examines the two casts of fossils that came from the same ancient turtle bone. [Read full story]
2 Halves
Together, the two halves reveal one of the largest sea turtles ever to have lived. [Read full story]
3D Scan
A 3-D scan of the two broken turtle limb fossils from Atlantocheyls mortoni shows a detailed view of their surfaces. Paleontologists from the Academy of Natural Sciences of Drexel University and from the New Jersey State Museum concluded these two fossils came from the same animal, despite being discovered separately at least 163 years apart.

Fitting bones
The two partial limb fossils from the ancient sea turtle Atlantocheyls mortoni fit together perfectly, leaving little room for doubt that they are from the same bone. The distal half (shown on the left) was discovered in 2012; the proximal half (at right) has been in the collections of the Academy of Natural Sciences of Drexel University for more than a century and is shown with its original labels. It was first described in 1849. [Read full story]
Hefty bones

A Giant
Now that paleontologists have assembled a complete humerus bone from the sea turtle Atlantocheyls mortoni, they have more information about the species and its overall size. Based on the complete limb, the researchers calculated the animal's overall size to be about 10 feet from tip to tail, making it one of the largest sea turtles ever known. [Read full story]
A loggerhead sea turtle with a tag. A new, less expensive technique can be used to track turtles just as accurately, according to a new study.
The ancient sea turtle may have resembled modern loggerhead turtles (shown here). In this illustration, it is depicted with the outline of a human diver to indicate scale. The turtle lived 70 million to 75 million years ago. [Read full story]
