Dasyatis sp.  - Male                       

This catalog contains other difficult to find shark and ray species of the Temblor Fm. of the Sharktooth Hill area  (mid Miocene -  15 million years old). Sharktooth Hill produces gorgeous and well preserved shark teeth. These teeth have excellent preservation and are great collector's teeth. New material from the Bob Ernst estate sale. Have a look at this rare offering from the Bob Ernst collection. It is very unlikely that you have a Heterodontus fin in your Sharktooth Hill collection! These are some of Bob Ernst's best!
