Those look like sea urchin 'spines'.

Subject: [Nhcoll-l] Possible dinosaur teeth ID

Hello!

I have two pendants in the collection where I work and we are trying to figure out what material they are made of. These pendants were found in Eastern Washington as part of an archaeological survey. The records indicate that they were identified as dinosaur teeth, specifically Diplodocus.

As I'm not an expert in the identification of dinosaur specific materials, I was wondering if someone could shed some light on these mystery pendants.

Each piece has smooth micro grooves running longitudinally along the surface, three pinched ridges at the crown, and a circular groove at the root. I am not sure if the groove is natural or man-made. They are over 2 inches in length (6.5 cm). I have attached a few pictures as examples.

Thanks!

Jennifer
