I was going through my old fossil collection with my 4 year old and I came across a bone that potentially has something, tooth?, embedded into it. The piece of fossilized bone is ~6x3 cm. About 2cm thick. Looks like any old fragment one might find laying around. When viewed from the side the periosteum? appears to be deformed and crushed. Embedded into crushed portion of bone is a fragment that looks like it could be a tooth or a piece of a tooth?
The embedded fragment is symmetrical, flat (~4mm thick) and is curved. Width is ~17mm. I can only see about 7mm of it before it is obscured by the bone so i don't know how long it is. I cant make out any serrations. There are 3 small protrusions on the visible edge that are 4x2 mm. These protrusions are comprised of one in the middle and one on each side. The photos make it look more irregular than it is.
It was decades ago when I found this but I would guess it was in and around Drumheller Alberta Canada. Doesn't help much but any more detail and I'd be guessing.
Probably just a concretion or nodule that caught my eye when I was a kid but I figured no harm in asking.
Cheers
