Any thoughts appreciated on the following. I've been working with some material from the Old Church Formation, including previously undescribed sites. The following tooth is from that work. It has most of the characteristics of an early Hemipristis curvatus (Or Hemipristis serra, if you follow Muller). Muller reports two possible teeth that are close to this shape from the Old Church: early Hemipristis serra and Galeorhinus aff galeus. What follows are three photos. 1) The tooth I found and am hoping to identify, 2) a Hemipristis serra from Muller, 1999 and 3) a Galeorhinus aff galeus from Muller, 1999. I lean strongly towards H. serra, but the tooth lacks serrations on the mesial edge. This makes me think that it may be a very early transitional or that there are some positional distinctions that I've not picked up on. The root and distal edge are much more consistent with H. serra. 1) The tooth I found and am hoping to identify (scale box=5mm): 2) a Hemipristis serra from Muller, 1999 3) a Galeorhinus aff galeus from Muller, 1999 (teeth labelled 1a, 2 and 1b) Full citation for photos 2 and 3: Müller, A. (1999). Ichthyofaunen aus dem atlantischen Tertiär der USA. Institut für Geophysik und Geologie. @Gizmo
