Shark, Ray, And Fish Micros From A Mosaic Mine In Florida


MarcoSr

Recommended Posts

I want to thank Bill for sending me almost a gallon of well washed matrix from a Mosaic Mine in Florida. A five gallon bucket of raw matrix taken directly from the mine washed down to one gallon using a .5mm sieve. I had asked Bill to use a .5mm sieve because I wanted to see if I could find several species which would fall through window screen. The matrix had a diversity of shark, ray and fish species from the Bone Valley Member of the Peace River Formation, Pliocene to the Miocene. The specimens that I found all had the really nice Bone Valley colors. There were, however, a lot of damaged specimens which could have been the result of the mining operations. This is the third post that I have made recently on micros from three different sites in Florida. The other two can be found at the below links:

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 including Carcharhinus, Rhizoprionodons etc.:

Marco, the broken specimen looks to be part of a Pristis lathami rostral tooth---Tom

Beautiful colors and pics as usual Marco!

Jeff

You need to find a spot in your Creek where the cookie cutters are red, yellow, green, blue, gray, black............ That would be totally awesome.

I do find some teeth in there that would be considered "bone valley" colors but I'd say it's maybe 1-2%

Every once in a great while it's not just a big rock down there!
