Claims of a mammoth tusk...

Recommended Posts

Posting for an acquaintance. Someone claims this is a mammoth tusk, and they're 100% certain. I'm not so sure. I've seen mammoth tusks in museums, and up close and personal digging one out of the dirt. I don't remember longitudinal striations like this object has. Can anyone tell me what it might really be?  Or confirm if it's actually a segment of a mammoth tusk?  Best pictures I've got, 3rd party source.

I'll go along with rudist as well. Can you please give us a close-up of the striations and also a view from the side, I mean the end of the object at the right where it's broken off.

you are right; those striations are NOT mammothy.  

Thanks for the advice, folks.  I think you've got it with rudists, probably radiolites.  I'm always amazed at the breadth of knowledge here!  :-)

Great find. If you get a chance to look at is again. Look for what is called "Schreger Lines" int he cross section. The lines are a tell tail sign of ivory.
