Newbie needs fossil ID

[Kat7]

Hello, I am a newbie writing from Florida, USA. However I’m inquiring about a fossil I discovered on a beach on Long Island, New York. I found it several decades ago. It was intact when I found it, however it was dropped by a child, damaging its integrity. I have retained the large pieces I could recover. In the meantime I’ve taken advantage of the ability to peek inside, in the hopes that will assist in identifying this object. Thank you for any information you can provide!

Not quite the same size,but down in Florida Peace River,  I would call this a Tilly bone. They come in all shapes and sizes

This appears to me to be the internal cast (steinkern) of a bivalve.

Thank you very much for your feedback! I think I will post this in the fossil ID section for any additional info. At first I thought it could be a Tilly bone, but that doesn’t quite fit. It does seem more likely to be a steinkern after further consideration. I will suggest that in the fossil ID post and see what others think. Thanks again!

Hello, I am absolutely new to this forum and fossil identification. I am located in South Florida. However, I am looking for identification for a fossil I found on the beach on Long Island, New York several decades ago. The fossil was intact when I found it, but unfortunately was damaged when dropped a few years later. I concur with one guess that it is a bivalve steinkern, but I am eager to have further feedback. If it is a steinkern, any ideas on the specific bivalve? Thoughts on the era it came from? If not a steinkern, what else might it be…bone? seed?

I don't think this is a steinkern. It has the shape of a hyperostosed fish pterigiophore, and it looks like bony structure on the inside. Here is a similar one-http://www.thefossilforum.com/index.php?/topic/41199-triangular-tapering-bone/

Please forgive me if this is a duplicate posting. I tried before but it seems it did not post. Wondering if I can get some input on a fossil I found on a beach on Long Island Sound. Is it a Steinkern? If so, any guess which bivalve? Is it a seed? Or a bone? Any thoughts on its age? Thank you for your feedback in advance.

Your previous effort did post but has been merged with the original post that you made. 

This one will likely go the same way.

I apologize. Is there a way to delete duplicate posts?

Thank you! It does appear to be similar. What do differences in coloration indicate, if anything?

Thanks, Coco.

I'm torn between saying yes and saying no depending on which section of the specimen I'm looking at. Also, it appears (if it is biological in nature) to be from a recent deceased organism. Let's let a few others chime in with their takes on this specimen.
