alej9582 posted a topic in Fossil IDHi guys me again, Anyone knows of a turtle with spikes on the Miocene of Florida? Regards, Alex
Hello everyone! I found this one today, and I remember finding another similar years ago. Is this some kind of tooth? in the same place there are a lot of marine fossils, as far as I know it is not a tooth of shark. Maybe a cetacean? Not far away I have found a vertebra of a whale. The moment (epic) when I found it: The old one: Salutes from the south, below latitude - 45. Chao!
emc2 posted a topic in Fossil IDI purchased it from eBay. It's from the Lance Formation of Eastern, WY. The exterior surface of the bone is pitted and has grooves just like a Triceratops brow horn. However, all of the Triceratops horns I have seen are conical, meaning they are round in cross section which this fossil is not. The cross section looks more triangular or diamond-like. This fossil has no compression or cracks in it which leads me to believe that the true cross section is more triangular or diamond-like than round in shape. The only other horns/spikes that would have surface bone texture like this and have that shape would be a large Ankylosaur side/shoulder spike. The fossil is partial so I cannot make a 100% definite ID either way so it is possibly a strangely shaped Triceratops brow horn section or a partial Ankylosaur side spike.
