Our friend @sharkdoctor sent us some micro matrix from the Old Church Formation in Virginia. This is our second batch and the first was fairly sparse but we did find some cool stuff. I haven’t searched much of this matrix but it’s already produced some nice teeth and has a better density too. There isnt, to my knowledge, any descriptions of Old Church material so my ID’s are just best guess. First pic- a beautiful little Galeorhinus tooth. Second pic- a really awesome Sphyrna tooth, maybe S. media. Third pic- a colorful Galeocerdo, I’d guess G. aduncas.

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

Hi everyone, Some time ago I was doing some prep on a block from the Phospate mines of Khouribga in Morocco (Cretaceous, Maastrichtian, 70 mya) with some Idgamanosaurus teeth in it. There were a lot of goodies in the block besides the two rooted Igdamanosaurus teeth like some coprolites, fish verts, a mosasaur tooth, Cretalamna tooth & Enchodus tooth. But I also found this little shark tooth which is around 2 mm in length, but I can't seem find a proper ID for it. So I was hoping that there might be someone here on the forum with some knowlegde on micro teeth from Khour

We recently acquired some micro matrix from the Cretaceous of Texas courtesy of our friend @Captcrunch227. I had a fun time searching the Post Oak Creek stuff and we crossed some stuff our want list. There are still several teeth that need id’s but I’ll have to wait a week or two before I can get pics to help that process. In the meantime, I do know some of what I found. We found several Nurse Shark teeth. I am relatively sure 2 are Cantioscyllium. I think 2 are Plicatoscyllium. Super excited to find a few Nurse Sharks. We found a couple of Rhinobatos tee

We got a very small amount of Lee Creek micro mix and it didn’t yield much in terms of volume but we did get a couple of excellent Hammerhead teeth, a Galeorhinus, and a few others. There are a couple of unsolved mysteries though. Up first is a 3mm mystery partial tooth. Under the scope this tooth bore no similarity to any other found. I looked through EVERY shark and batoid tooth picture for Lee Creek on Elasmo. The tooth that came the closest was actually Megachasma but I’m convinced that can’t be correct. The root is not intact and I can’t do any better on the pictures for now

That little vial of micros from the Mesaverde formation is the gift that keeps on giving. I dissolved some of small bits of matrix in vinegar. Still no batoid teeth but a couple of shark teeth did emerge. Mesaverde Formation, Rollins Member Colorado The first is a candidate for the smallest shark tooth in my collection. At most it is 1mm and I think it is another possible Cat Shark tooth. Quite similar to some NJ teeth I found on line. I am open to other possibilities as far as an ID goes. Regardless, it is one very cool looking micro tooth

I have been slowly going through both the Cretaceous micro matrix from the Mesaverde formation and the Permian micro from the Council Grove Group of Kansas. I have found quite a bit of partial shark and ray teeth from the Mesaverde stuff but have not photographed it. So far the Permian mix has been a different story. The fossils are much smaller and there has been little shark material. I am not too upset though as I have only been through about 1/3 of it. The fossils are so small it takes quite a bit of time to go through. We did have a little success though and I am quite thrille

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
