bthemoose Posted July 8, 2021 Share Posted July 8, 2021 The two shark teeth below are recent personal finds from the Nanjemoy Formation (early Eocene) in Maryland. I'd appreciate any help in ID'ing them. #1: Jaekelotodus robustus? I've been calling this one Jaekelotodus robustus and am curious if that's correct. This tooth measures 27 mm on the slant. #2: Brachycarcharias lerichei? This second tooth has me stumped. I'm leaning toward Brachycarcharias lerichei, but would not be surprised to find out it's something else! This tooth measures a little over 22 mm on the slant. Thanks in advance for any help you can provide! Link to comment Share on other sites More sharing options...

bthemoose Posted July 10, 2021 Author Share Posted July 10, 2021 @hemipristis, I think you might be right about that one--the cusplets seemed too triangular to me, but I'm more familiar with S. striata than macrota and from the Elasmo dentition it looks like a pretty good match.
