bthemoose Posted April 30, 2020 Share Posted April 30, 2020 Hi, I made a few visits earlier this spring to the Potomac (Aquia formation) in Maryland and collected a bunch of shark teeth, most of which look like Striatolamia striata with quite a few likely Hypotodus verticalis as well. I'm hoping to confirm my IDs of a few potential Otodus obliquus and Cretalamna appendiculata teeth as well as get help identifying some others. The teeth in question are below--I'll include composite photos from different angles in reply posts. I've currently categorized teeth #1-3 as Otodus obliquus, #4-6 as Cretalamna appendiculata, and #9-14 as Hypotodus verticalis (based in part on the absence of striations). Teeth #7-8 look like something else to me--could they be Brachycarcharias lerichei? Thanks in advance for your help! Link to comment Share on other sites More sharing options...

bthemoose Posted April 30, 2020 Author Share Posted April 30, 2020 And here are the rest (#9-14), which I'm currently calling Hypotodus verticalis. Thanks for looking! Link to comment Share on other sites More sharing options...
FossilsAnonymous Posted April 30, 2020 Share Posted April 30, 2020 Your Otodus are correct. So are your Cretalamna. However, once you try to get into distinguishing the multitude of sand tigers from each other, things become a lot harder to identify. 1 On The Hunt For The Trophy Otodus!
