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. <br><br>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. <br><br>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. <o:p></o:p></p></div><p class=MsoNormal style='margin-bottom:12.0pt'>Thanks!<o:p></o:p></p></div><p class=MsoNormal>Jennifer <o:p></o:p></p></div></div></body></html>
