karenilm Posted January 31, 2018 Posted January 31, 2018 I may be completely off track but could this be a small partial molar? Also including 2 teeth I found close by.. Thank you for taking the time to look!!!!!
digit Posted January 31, 2018 Posted January 31, 2018 Where were these found? Your odd little specimen has the familiar look of a Tilly Bone (hyperostotic fish bone). Do a search on this forum for "tilly bone" or "hyperostotic". For even more images do a google image search for the same and you'll see lots of photos similar to your find. They are unusual bones and their purpose seems to be a bit of a mystery though I've seen various papers suggestion anything from a calcium "reserve" to effectively a bone tumor. Your other finds do seem to have an enamel surface and seem to be worn shards of larger (shark?) teeth. More information on where these came from would help to be more certain. Cheers. -Ken 6
caldigger Posted January 31, 2018 Posted January 31, 2018 I believe the first one is a "tilly" bone from a fish. Second, chunks of unidentifiable bone? **Oops, Ken beat me to it! 2

I'm no expert in fossil ID but for items I see a lot of first hand (like Tillys) I do develop a bit of a search image so it is nice to be able to contribute when possible. Cheers. -Ken 1
Tidgy's Dad Posted January 31, 2018 Posted January 31, 2018 That tilly bone is lovely! Good find! 1 Life's Good! Tortoise Friend.
abyssunder Posted January 31, 2018 Posted January 31, 2018 The first specimen might be a sea robin hyperostosed skull roof, close to Prionotus. 3 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

karenilm Posted February 1, 2018 Author Posted February 1, 2018 digit - Thank you!! I seem to have a knack of finding the tilly bone! Thank you for your help in identifying. I found these in North Carolina @ Wrightsville Beach. I've found 3-5 different looking types which has thrown me off ID'ing them. THANK YOU! caldigger - Thank you! doushantuo - Thank you! Why thank you Tidgy's Dad!!!! abyssunder - Thank you!
sixgill pete Posted February 1, 2018 Posted February 1, 2018 I believe @abyssunder got this one right. I believe also it is a sea robin skull.

karenilm Posted February 1, 2018 Author Posted February 1, 2018 Sixgill Pete-- I thought @abyssunder was suggesting that it's a sea robin skull but the skull roof is a Tilly (hyperostosed) skull roof??
abyssunder Posted February 1, 2018 Posted February 1, 2018 There are usually three types of hyperostosed fish bones: vertebrae, vertebral spines and skull elements. They all are known as "Tilly bones". Don is referring to the latter, not to the most common one (vertebral spine). Your specimen, as I think, is a deformed sea robin skull roof with hyperostosis. hyperostosed vertebrae picture from L. L. Capasso. 2005. Antiquity of cancer.
