Shellseeker Posted May 9, 2019 Share Posted May 9, 2019 I always have stuff that could be IDed because I am always imagining that it is something that it is not... may be true here also: Whenever I see the multiple holes in a line , I think tooth sockets and thus Jaw. But here I am pretty sure that is not what I have. So, if not jaw, it must be turtle scute, but this is ODD for turtle.. Anyone come across something similar? That for all comments and suggestions.

Mark Kmiecik Posted May 9, 2019 Share Posted May 9, 2019 I'm no expert, but could the first one be a sawfish rostrum? Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...

I have seen some Sawfish Rostrum, and I can see the similarities between them and this fossil. There is great diversity in rostrums, so I can not be sure that it is not one. This seems to be an osteoderm or scute that you might find from turtles, but it also has what seems to be tooth socket holes on each edge. I am sort of expecting someone to have seen it before or at least hope that happens.

MarcoSr Posted May 10, 2019 Share Posted May 10, 2019 The form of the first specimen does resemble a sawfish rostrum with rostral tooth holes on each side and canals running down the inside. However, rostrums are cartilage not bone, as Eric states above. You need to look at the specimen surface under magnification. If no prism pattern is seen, then the specimen isn't a rostrum. I really don't have any other id suggestions. Marco Sr. 1 "Any day that you can fossil hunt is a great day."

Carl Posted May 13, 2019 Share Posted May 13, 2019 Could it be a keeled sternum with the divots being were the ribs attached? 2 Link to comment Share on other sites More sharing options...

I suspect you mean "raptor" as in "bird of prey" rather than "dromaeosaur," but I guess either would work as sterna like this are present in both groups, and they are certainly more widespread than just those 2 groups. But as this was (I'm guessing) found in Florida, there's virtually no chance it's a dromaeosaur anyway. Link to comment Share on other sites More sharing options...
