I just found this 17mm tooth today (see the below pictures) in matrix that I collected from the Eocene, Nanjemoy Formation, of Virginia awhile back. I thought that the tooth was an Otodus obliquus symphyseal tooth and sent a PM to Lutz Andres to get his opinion of the tooth. He responded back:
“Hi, it's a lower symphyseal Otodus or Parotodus, and 17 mm is a bit large for Parotodus.”
Because of the 17mm size and the fact that Parotodus is not reported from this Formation, I’m going with the Otodus ID. I have a number of Otodus obliquus symphyseals from Morocco but this is the first one that I have personally collected from Virginia. My friend Mike F. has collected two Otodus obliquus symphyseals from the same formation.
