Hopefully it still counts as it's in the time period.

How about this from the Eocene, it looks very similiar to the uk auriculatus teeth

Great tooth, Will.  Something is weird with that label.  The Nanjemoy Formation is Early Eocene age and it's part of the Pamunkey Group.  Otodus obliquus teeth are rare but you can also find weakly-serrated specimens.  I've never seen one as well-serrated as that specimen from the formation but then your specimen is from the upper part of the Nanjemoy from which something like that could be expected.  My most recent reference has the Woodstock as the upper member of the Nanjemoy.  Maybe @MarcoSr or one of the other Nanjemoy collectors can comment.

The Woodstock Member of the Nanjemoy Formation is Early Eocene as you stated and not Late Eocene as on the label.

 

The upper Woodstock Member (not Formation) of the Nanjemoy Formation at Popes Creek, Maryland, USA does have O. auriculatus.  From the specimens that I have from Popes Creek, I can believe that this specimen could definitely be from the Woodstock Member at Popes Creek.

Really nice tooth.
