I found this unknown fossil specimen several years ago along Calvert Cliffs, MD.  I have two of them now and don't know what they are from.  They are definitely fossils, and for some reason I think they are some sort of fish fossil?  They feel quite solid, not hollow.  Anyone out there know what this thing is or have one like it?  I posted a larger pic in the Maryland trips section.

I was doing search earlier today for a possible tusk and saw a mammoth tooth that looked very similar to this picture.  I think the long skinny part is the root and the picture on the bottom right looks like the chewing surface.

I'll post pics as soon as I can retrieve the specimens from storage.  I'm also hoping to get some ID help from the Calvert Marine museum, or the NMNH in DC.

thanks,

Thanks for the ID info Xiphodan.  I hope to get a confirmation on that from the museum soon.  I've always suspected it was some sort of fish fossil, but could never figure out what part.  I did a quick search on fish brain cases but didn't turn up anything that looks quite like my specimen yet.  One reason for thinking that this specimen was a fish fossil of some sort is because if the blackish colored patina covering it.  I have some large fish vertebra I believe that have this same coloring.  The verts might be Tuna but I'm not sure.  I'll have to dig them out to look at them again.
