WAHAMA90 Posted February 25, 2017 Author Share Posted February 25, 2017 They were found at Brownies Beach,Md so they are Miocene teeth. The second one is about an inch wide and tall. Link to comment Share on other sites More sharing options...
NSRhunter Posted February 25, 2017 Share Posted February 25, 2017 Small lamnid shark from the older reworked layer of Paleocene material from Borwnies for the first maybe? And also probably retrolexus for the last? Link to comment Share on other sites More sharing options...

And also probably retrolexus for the last? That's what I thought for both, but when I asked a question before about an older tooth showing up there it was shot down. For the mako this is the only one that I have found that was this color that's why I had a question about it. Link to comment Share on other sites More sharing options...

MarcoSr Posted February 26, 2017 Share Posted February 26, 2017 There absolutely isn’t a reworked Paleocene layer at Brownies Beach. The base of the cliffs is Miocene Zone 3 Fairhaven Formation. Further north at Fairhaven the base of the cliffs is also Zone 3 Fairhaven Formation. There are places in MD like Popes Creek where Zone 3 Fairhaven Formation overlies a reworked Eocene layer. So it is possible that somewhere in the Chesapeake Bay teeth from this Eocene reworked layer are washing into Brownies Beach. However to me a more logical explanation is that it is a contaminant. Groups who sponsor children’s beach fossil hunts dump all kinds of stuff on the beaches for the kids to find. I’m strongly against this type of beach salting because it adds all kinds of contaminants but unfortunately it happens all the time. I can tell you that I collected Brownies beach in the 1970s and 1980s extensively and never found a single reworked Eocene or Paleocene tooth. However, I do find on rare occasion reworked Eocene teeth far down river on the beaches with Miocene cliff exposures along the Potomac River.
