Remember this? When I posted it I thought it might be a dinosaur tooth, but several commentators (Petern, Avalus, kestrel, Jazzlet) suggested it might be coral of some sort. It was Oggie, though, who took the time to look it up and told me it was
think it is a rugose coral. Middle Ordovician to late Permian. Yet another victim of the PT extinction event – comment section Is this a Dinosaur Tooth?
Well, Oggie was absolutely right. I sent the photos off to The Royal Ontario Museum and they concur. Although they can’t say with certainty without seeing the piece in person, they suggest that it is horn coral, of the order rugosa from the Ordovician period. Mystery solved!
Thanks to everyone for your help and suggestions.

Great that they got back to you, along with a little smuggness at being right ;-)

That’s really cool, thanks for the update! I remember and I was also curious to know what it was.

Yay for science!
Thanks for the update, it’s such a beautiful piece and it got even better, now that we now what it is. :)
