FloridaLemonShark13 Posted April 11, 2021 Share Posted April 11, 2021 Wading in one of the creeks in my neighborhood provided a few small fossils and I found a interesting looking mouth plate. This is a late Pleistocene area, and in the Tampa member of the Arcadia formation, and the other finds I’m wondering is are these alligator scutes or could I be wrong?

Al Dente Posted April 11, 2021 Share Posted April 11, 2021 It looks like a very worn burrfish or porcupine fish toothplate. 1 2 Link to comment Share on other sites More sharing options...
FloridaLemonShark13 Posted April 11, 2021 Author Share Posted April 11, 2021 I thought pufferfish or parrot fish, I’m gonna go with puffer fish on this Link to comment Share on other sites More sharing options...
digit Posted April 11, 2021 Share Posted April 11, 2021 Yup. Trust @Al Dente on this one. Pufferfish have these stacks of hardened plates behind their arc of teeth. Occasionally, you'll find them with the little teeth still attached along the edge. The last photo above seems to be a different (and larger) object with an interesting texture. We could use other views of that if you are seeking an ID on that one as well. Cheers. -Ken 1 1 Link to comment Share on other sites More sharing options...

jpc Posted April 13, 2021 Share Posted April 13, 2021 Raising my hand from deep within the Cretaceous and Eocene....I don't have the fish knowledge that these others folks have, but that is not an alligator/croc scute. Link to comment Share on other sites More sharing options...

Crocodilian osteoderms definitely have that pockmarked surface but in my limited experience there is more separation between the depressions. The more "orange peel" surface on the item in question reminds me very much of the texture of Holmesina osteoderms. Some of them have a bit of a keel to them which is also a characteristic of the crocodilian osteoderms. Another characteristic of most of the Holmesina plates is the narrow tapered edge around the osteoderm where it is thinner than the body of the osteoderm. This is not seen in crocodilian osteoderms which simply taper-off gradually from the thicker keep to quite often a knife-edge around the perimeter. Would be interesting to see this object in profile view to gauge the thickness and to see it from below. This object is interestingly oval (more crocodilian-like) which is less like the rectangular or hexagonal osteoderms usually found on the body but could be one of the more unusual shaped ones on the head or tail or other curved surfaces. Not stating that this is Holmesina but only raising the possibility. Cheers. -Ken 1 Link to comment Share on other sites More sharing options...
