the final results of our first two Paleozoic micro shark hunts
fossilsonwheels posted a topic in General Fossil Discussion
We started working on two early forays into micro fossils over a year ago when we cracked open the vile of Permian matrix from Kansas. Those tiny Neva Formation formation fossils and the even older and smaller Genundewa Limestone fossils proved to be extremely challenging, sometimes very frustrating and all kinds of fun. The results were few shark fossils that made it from matrix to the safety of the display cases lol There were several lost or broken shark teeth and one pulverized to dust by a millimeter worth of thumb slippage. If we judged this by volume, one could say this was- 4 replies

We have recently picked up some rather interesting micro shark teeth from the Paleozoic. Originally this was our way to get some older shark fossils to show students but I am actually pretty interested in continuing to collect micros from this period. First up, the oldest Chondrichthyes fossils we have and as I understand it, the second oldest yet found. Denticles Upper Ordovician Harding Sandstone Colorado I read that these had been given a name, Tezakia. Not sure if that is still valid or if these denticles match those described.

I was going over some of bits of Permian micro mix from the Neva Formation in Kansas and I found a fossil I had come across in my initial search months ago. I recently looked at a publication on Permian sharks from Russia. I remembered seeing something similar in that publication. It was a monocuspid denticle attributed to Cobelodus and I can not help but wonder if our mystery fossil is chondrichthyes denticle of some sort. Any thoughts ?

Micro Fossil Report- Our first foray into the world of micros
fossilsonwheels posted a topic in General Fossil Discussion
I thought it would be fun and possibly helpful to other collectors to discuss the results of my first foray into the world of micro fossil exploration. I had purchased some quantities of micro matrix from two different formations and they provided vastly different experiences for me as a collector. I got a vial of micro fossils from the Neva formation which is from Kansas and is Permian. This stuff really proved to be quite a challenge and was not ideal to start with. These are TINY fossils and I was not equipped to handle such small fossils. Identifying the shark material was chal- 9 replies
