At first glance, on the beach, I thought this was a pink Petoskey stone / Hexagonaria, but there are no visible bands or gills. Any thoughts?

I want to thank John S. for sending me three gallons of well washed gravel from Joshua Creek in Florida. Joshua Creek has species from recent to the Miocene. The fossil density was not as high as the Peace River but there were some nicely persevered specimens. I found shark, ray and fish fossils, a small mammal tooth, several crustacean specimens and maybe a Native American bead. I am posting some of the nicer and more unusual specimens which I found which range in size from 2mm to 13mm. There are specimens that I do need id help with. If you place your cursor on a JPEG image you will see the file name which will have the specimen id as best that I can determine and the specimen size. If you can identify the specimens further please do so. Each matrix that I search makes me more of an avid micro tooth collector. If anyone has or can collect good matrix with shark, ray, and fish micros please send me a PM. Some of the shark teeth which I found. Note there were a large number of Rhizoprionodon teeth in this matrix.: Carcharhinus: Rhizoprionodon including a slightly pathological tooth: A shark tooth that I would like id help for. Maybe just another Rhizoprionodon: Some of the ray teeth, a ray barb and a ray dermal element which I found: Dasyatis: Rhynchobatus: Ray Barb: Dermal element: Several partial fish mouth plates, a very nice Gar scale and some of the fish teeth which I found: Continued in the next reply.

I want to thank John S. for sending me three gallons of well washed Peace River gravel from Florida that was ready to search. The Peace River has a very large diversity of species from recent to the Miocene. There were a lot of specimens in the gravel but a lot were damaged and/or water worn which is typical with river gravel. I found a large number of shark, ray and fish fossils, several mammal fossils, several alligator teeth, and a good number of snake vertebrae. There are specimens that I need id help with. I am posting some of the nicer and more unusual specimens which I found which range in size from 2mm to 13mm. This is my second Post of micros from the Peace River. My first Post can be found at the below link: http://www.thefossilforum.com/index.php?/topic/42036-shark-ray-fish-and-other-micros-from-the-peace-river-of-florida/ If you place your cursor on a JPEG image you will see the file name which will have the specimen id as best that I can determine and the specimen size. If you can identify the specimens further please do so. Each matrix that I search makes me more of an avid micro tooth collector. If anyone has or can collect good matrix with shark, ray, and fish micros please send me a PM. Some of the shark teeth and a shark vertebra which I found: Carcharhinus, There were multiple species: Hemipristis: Isogomphodon: Ginglymostoma, I don’t know what they ate, but they always seem to have feeding damage to the crowns: Sphyrna: Continued in the next reply.
