PolskiByk Posted February 14, 2018 Share Posted February 14, 2018 These teeth were found along the Potomac River in Western MD, in the Aquia formation. I am having a tough time finding information on teeth from this location but I believe these are possibly Pigmy White teeth (Palaeocarcharodon orientalis). All six show signs of serrations, but there are other teeth from the Paleocene that might look similar? I need help identify them and don't want to mislabel them in my collection. Also I found these two smaller teeth with serrations on one side but they seem unlikely to be Pigmy Whites. Any idea what they are? 1 Link to comment Share on other sites More sharing options...
Darktooth Posted February 14, 2018 Share Posted February 14, 2018 In the first pic some are definitely pygmy white shark though I hesitate to say they all are. The two teeth in last two pics are a type of tiger shark. 1 I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
FossilDAWG Posted February 14, 2018 Share Posted February 14, 2018 Elasmo is a great resource that will tell you what you need to know to ID your teeth. Click on "Faunas" at the top, then on "Aquia". Your last two teeth are likely Pachygaleus lefevrei. I'm comfortable with Paleocarcharodon for the rest. Some of those are really beautiful!
