From the album: Devonian
A Phoebodont shark tooth dwarfed by the head of a pin - they are very tiny and difficult to manipulate. From the Genundewa Limestone.-

From the Genundewa Limestone. These conodont elements seem to compare well with Polygnathus linguiformis. https://doi.org/10.1007/s12542-018-0408-6-

From the album: Devonian
These shark teeth are very brittle and fragile - finding a complete one seems very unlikely. From the Genundewa Limestone.-

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 wasn’t successful. I would call it an overwhelming victory for us. We didn’t find a lot but we nailed our three target morphologies plus we found an unexpected gem. The goal with the Neva material was simple Oceans of Kansas website provided the examples of a small unnamed Ctenacanthiformes/Cladodont tooth from this formation. That was it. I only needed one and we found 3. Unfortunately the first got crushed. The second found by our friend @Tay Francis but I lost it. It was on our third and final complete search that yielded one last Cladodont. This one survived and made to it’s final home in our display. Our youngest tooth in this order. Victory after a few defeats is no less a victory lol The Devonian Genudewa from New York yielded a half dozen partial Phoebodus type teeth. We also found 4 partial Omalodus teeth.Omalodus is also a relative of Doliodus. For me, this is so cool. We found a connection to a transitional shark ! The biggest surprise was a tooth that seemed a very close match to teeth I’ve seen described as Wellerodus, a relative of Antarticlamna. Devonian era New York does have some descriptions of these tooth morphologies and my tentative ID’s are based on publications so Im fairly confident in saying we found a couple of teeth from important early shark families. I’ll be starting another round of Paleozoic micro shark hunts including a return to both of these formations with new matrix. We will be better prepared with micro fossil slides and better handling. We are going to try a few different matrix samples including Maple Mill. I will get better pictures when I can but I’m just glad to have finally finished sorting and separating these tiny delicate teeth. First pic is the Kansas Cladodont Second pic on the left are Phoebodus, the right holds Omalodus and possible Wellerodus teeth.- 4 replies
