Supersized Tilly Bone? Looks like a Large Gummy Bear. Do you agree on the fossil? Not dense at all. Looks like a sample I have collected already...but this one is very large. 7 cm long, 4.2 cm wide This is a good reference piece. -Michael

I've bought this as a coprolite a long time ago. I don't have an exact location, but the person I bought it from dives costal rivers in the Southeast United States. Something about this one always seemed a little weird. As I have been re-photographing my coprolites, I discovered one specimen in my collection that was actually a tilly bone. It had been mounted in a plastic display case, so I had never looked at the bottom. The composition of this seems similar to that specimen. But I do have true coprolites that also have that surface texture. I know at one time I thought this might be a cololite or a steinkern of some sort, but that didn't seem quite right either. What do you all think? The bottom view is the one that I thought might be diagnostic. Thanks for looking!

Hello all! Sorry for the not-so-great photos here. My phone camera is... kind of a fossil. I found this mystery fossil on the beach in North Carolina, USA, somewhere near Emerald Isle if I'm recalling correctly. My best guess is that it's a periotic bone from a dolphin, porpoise, or something of the like, but it doesn't totally match up with images I've seen. I've also considered that it could be a ballast bone, but again, hard to confirm via Google search. Any thoughts would be appreciated!

Would these be tilly bones of some sort? I have found the heart shaped tilly bone but never this shape. Thank you so much

As I have investigated many unidentified and differently formed fossils, Tilly bones, almost always comes up. Is "Tilly Bone" a catch-all term?

Here's another interesting fossil that turned up in my storage . . . a Tilly bone that has been sawed in half. I took some close-ups with my camera (unhappily, my microscope camera software is not compatible with my new Intel Core i5 processor). But, I think you can see the gross structure and identify the bone, a pterygiophora ("ter-RIJ-ee-AH-for-ah", I think). Tilly bones are bone overgrowths of unknown etiology. This one is from a fish axial skeleton with bilateral symmetry. A pterygiophora is the basal spine (within the fish body) which supports and articulates with the dorsal fin spine on the body exterior. Show us some more Tilly bones.
