ted coulianos Posted March 23, 2014 Share Posted March 23, 2014 1. Thought this was an oddly curved posterior Meg, but maybe Thresher Alopias?? Calvert Fm, Westmoreland St.Pk, Virginia. 2. Posterior Meg or Thresher?? Calvert Fm, Chesapeak Beach, MD; more worn than #1 above, but very similar. 3. Notorhinchus (Notidanus) upper or Echinorhincus blakei?? Calvert Fm, Chesapeake Beach, Maryland Any help making a positive id would be appreciated. Thanks in advance. Link to comment Share on other sites More sharing options...

Auspex Posted March 24, 2014 Share Posted March 24, 2014 1. looks like a serrated Alopias Grandis... I was hoping that was the case!

MarcoSr Posted March 24, 2014 Share Posted March 24, 2014 I was hoping that was the case! What an awesome tooth Although extremely rare, Westmoreland is a good location for nice, serrated giant threshers. However, with the cliff areas now closed to collecting there, they would be even rarer from the small beach collecting area. Marco Sr. "Any day that you can fossil hunt is a great day."
