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?
