PSchleis Posted January 6, 2019 Share Posted January 6, 2019 (edited) Ok, found this one tonight walking Myrtle Beach. It kind of reminds me of a walnut shell. The center seems to be some kind of seam. I'm including a photo of the opposite side but it's not as great as I hoped. Hard to show detail, but it's concave as if it held something. Ideas? -- Paula Edited January 6, 2019 by PSchleis finetune title description Link to comment Share on other sites More sharing options...

I adjusted the title on this thread to reflect it. What a cool little piece. Amazing detail! Link to comment Share on other sites More sharing options...
PSchleis Posted January 6, 2019 Author Share Posted January 6, 2019 While looking up sea robin skulls, I couldn't find any that resembled what I had, but I came across this photo that was labeled "baby alligator head." Does this look closer to what I have? Link to comment Share on other sites More sharing options...
caldigger Posted January 6, 2019 Share Posted January 6, 2019 The picture you posted above is a Sea Robin skull. I think the object you have looks more like a "Tilly bone". 2 Link to comment Share on other sites More sharing options...

PSchleis Posted January 6, 2019 Author Share Posted January 6, 2019 Ok, I found another skull plate on the beach today (left). It matches images I've been finding that are identified on the Internet as a searobin skull plate. But I don't see any resemblance to that and the other fossil I found yesterday (right). Aren't these two different things? Also, I've looked up "tilly bone" images on the Internet. I can't find a tilly bone image that looks anything remotely like the photo in my original post. Still confused! 1 Link to comment Share on other sites More sharing options...

There are some extensive threads here dealing with Tilly Bones, with plenty of illustrations. I am of the Tilly bone persuasion for your find. 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...

A tilly bone is a deformation that can happen to any bone in a fish. Most are not from the skull elements of the skeleton, but some are. I agree that Your piece is a deformed (tilly) bone from the skull of a fish (sea robin or other.) 3 hours ago, PSchleis said: But I don't see any resemblance to that and the other fossil I found yesterday (right).

I've spent hours looking for a "tilly bone" or a "searobin skull plate" that looks anything like mine - to no avail. I'm going to give up and take y'alls word for it! Very much appreciate the help. -- Paula Link to comment Share on other sites More sharing options...

There are several threads about tilly bones and sea robin skulls. Keep in mind that Your piece has bulbous deformations compared to a normal piece of fish skull. Also "sea robin" is two words. 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Thanks again. I've been searching the fossil forum pages in complete awe of the wonderful resource collected here. I can't get enough of this site. There is so much to learn. I've wasted so many years just looking for shark's teeth when all these other wonderful things were right beneath my feet. Anyway, I've got more fossils to post but trying not to outstay my welcome so limiting them to one a day! Link to comment Share on other sites More sharing options...

Plax Posted January 7, 2019 Share Posted January 7, 2019 back in the day these particular "tilly bones" were called bony fish basi-occipitals. Am not up on the current Tilly Bone nomenclature though. I thought Tillys were hyperostosed verts etc. Just stating my ignorance not an opinion. Link to comment Share on other sites More sharing options...
Harry Pristis Posted January 7, 2019 Share Posted January 7, 2019 They were called "ballast bones" also, but that idea was discounted. This object doesn't much resemble any fish basioccipital that I could find in a google search. One important clue that this bone is not part of the axial skeleton is the lack of bilateral symmetry. A careful examination reveals that the lobes and other parts are not symmetrical. Slight to significant asymmetry is typical of Tilly bones.
