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.
