The Jersey Devil Posted May 1, 2020 Share Posted May 1, 2020 Hi everyone, I would like to ask about these ray teeth from Calvert Cliffs. All I know is that some of them are Aetobatos I think.

MarcoSr Posted May 1, 2020 Share Posted May 1, 2020 The below table from Godfrey 2018 The Geology and Vertebrate Paleontology of Calvert Cliffs Maryland USA lists batoid genera from Calvert Cliffs. So from your pictures, your specimens could be Aetobatus, Pteromylaeus, Rhinoptera or Plinthicus. Marco Sr. 5 "Any day that you can fossil hunt is a great day."

sixgill pete Posted May 1, 2020 Share Posted May 1, 2020 I agree with @MarcoSr. The one on the far right bottom does appear to be Plinthicus to me. 2 Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...

The Jersey Devil Posted May 2, 2020 Author Share Posted May 2, 2020 @sixgill pete @MarcoSr Are these possibly identifiable? I think they are dolphin/porpoise ribs, 2 ear bones, maybe a ratfish chunk (probably just an odd bone piece), and some other type of bone. “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...

Those look like rib bones but cetacean rib bones aren't really diagnostic. Your two specimens don't look like any ear bones that I'm familiar with. I agree on an odd bone piece. The last specimen looks more like an internal shell cast to me. Marco Sr. 1 "Any day that you can fossil hunt is a great day."
