maya14 Posted November 17, 2022 Share Posted November 17, 2022 Good morning everyone! I was hoping someone would be able to help me identify this weird looking fossil. I researched it for days and think it may be a really worn down sea robin skull! It is the size of a US quarter (24.257 mm in diameter) I found it while sifting for sharks teeth in Fernandina Beach, Florida (Nassau county). Anything helps! Thanks in advance!

Mark Kmiecik Posted November 17, 2022 Share Posted November 17, 2022 Tilly bone is what came to my mind as well. 1 1 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...

Harry Pristis Posted November 17, 2022 Share Posted November 17, 2022 I am skeptical that this is a Tilly bone; but, we need more views and better focus. 2 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
ClearLake Posted November 17, 2022 Share Posted November 17, 2022 This looks a lot like a broken vertebra, maybe turtle. I'll see if I can find an close analog to what I'm thinking. 1 Link to comment Share on other sites More sharing options...
ClearLake Posted November 17, 2022 Share Posted November 17, 2022 This is from a modern Snapping Turtle which may not be the same as yours but I'm just trying to demonstrate what I think I see. These are the neck vertebrae and yours would just be the upper part of the vert, the body of it is missing. The two "prongs" would be the articulating surfaces with the next vert. I'm certainly not positive, but that's what your find reminds me of. 1 Link to comment Share on other sites More sharing options...

Al Dente Posted November 17, 2022 Share Posted November 17, 2022 (edited) Looks like Fin Lover beat me to it. I think this is a hyperostosed fish neurocranium. Similar looking fossils are found at Ponte Vedra in Florida and Myrtle Beach SC. Here’s Ponte Vedra fossils from this thread-http://www.thefossilforum.com/index.php?/topic/74763-need-more-help-with-fossil-id/ And Myrtle Beach from this thread-http://www.thefossilforum.com/index.php?/topic/85616-found-at-myrtle-beach/ Edited November 17, 2022 by Al Dente 4 2 Link to comment Share on other sites More sharing options...

Why do you think the OP's find is hyperostosed? Looks to me to be a normal part of a neurocranium. http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...

Why do you think the OP's find is hyperostosed? Looks to me to be a normal part of a neurocranium. I said hyperostotic because I am a beginner and that is what the book I have says. I don't know enough to be able to tell the difference between regular and hyperostotic. I have no doubt that Al Dente can give you a reason, though.

Al Dente Posted November 19, 2022 Share Posted November 19, 2022 11 hours ago, Harry Pristis said: Why do you think the OP's find is hyperostosed? Because it is a noticeably thickened skull element. Bones of typical fish skulls are thin and flaky and normally won’t easily fossilize under most conditions. Thickened bones will more easily fossilize and in some deposits will be concentrated and readily found. I frequently collect in the Rushmere Member of the Yorktown Formation where fish bone is abundant but the vast majority is hyperostosed, normal thin flaky fish bone just doesn’t last long while thick bone becomes mineralized and concentrated in the deposit. 5 1 Link to comment Share on other sites More sharing options...
