This one of the things that makes fossil-hunting interesting and fun. Here is the remains of a Megalodon's meal that I found on our most recent fossil-hunting expedition to Bone Valley.

Exact species unknown.
Miocene (5 to 23 million years)
Sarasota County, Florida
Bone Valley Formation
Hawthorn Group

This is the proximal end of a thoracic rib from an unknown species of Cetacean. Of note, one end has clear predation marks in the form a series of evenly-spaced, parallel gouges into the surface of the bone. This was likely caused by a shark and possibly a small Megalodon.

Note, the photo of the guy holding an intact rib is shown for comparison. The portion circled in black is the part of the rib I found. Obviously the man in the photo is not me, because I am far sexier than that poor fellow. It's not his fault. LOL. (Image credit : Wikimedia Commons)
