Hi y'all, I found this strange micro Permian tooth. I haven't seen anything like it. It's from Waurika, OK (Wellington Fm.?, Early Permian), has textured enamel, has a broad crown but is VERY thin/compressed, and shows slight crenelations/serrations? on the edges. It's about 2 mm in height. It's not a fish tooth or scale (otherwise there'd be enameloid on only one side were it a scale), not Orthacanthid "shark" (textured enamel, broad, compressed crown), not amphibian (not conical or labyrinthodont), which leaves reptile or synapsid. Any help to narrow it down further would be very much appreciated. @jdp@dinodigger Side profile: Basal view:

Made a trip to the upper Pennsylvanian Bond formation today. I hadn't been to this locality in probably three years or so. I don't recommend hunting in 90+ degrees Fahrenheit. Ameura I made some slices from the top of the cut which is filled with microfossils, foraminifera. These aren't the best pics ,however, just using my cellphone so clarity isn't that great; there are some interesting little organisms hiding in there.. 40x magnification 100x Thanks for reading.

To find denticles, you need to go to the finest grain size. This beautiful one could be shark, but I'm not certain.-

Rhinobatos teeth are probably the smallest teeth you can hope to find here - they are about as small as grains of sand.-

I grew up in Austin, going to Shoal Creek and Barton Creek and my local backyard creek, picking up the odd fossil or rock and stashing it away. It has only been recently (within the last 8 years) that I really got interested in Paleontology and finding out about the formations and proper fossil names etc....so it's been fun to revisit a lot of the places I went as a kid and see them in a whole new light. When the Paleontological Society of Austin used to hold meetings in person, I'd go up to Austin early and go fossil hunting in Shoal Creek - it has easy access and is a hop skip and a jump from the meeting house. And I've found a lot of great stuff there - ammonites, echinoids, etc.. But....now I have discovered the world of Microfossils! So I got myself a gallon baggie of creek matrix, not really knowing what to expect aside from the ever present Ram's Horn Oysters (Illymatogyra arietina) which are found in the millions there. And WOW.....I was astounded! Lots of great stuff from the various formations that make up Shoal Creek - Buda, Georgetown, Eagle Ford and Del Rio/Grayson. Some of the fossils I can pinpoint to specific formations, others, not so much. So here are my favorite Shoal Creek Micro Fossil Finds! First up- The Crab Claws! So many little tiny crab claws of all kind of species. These are all 3-5 mm And the Brittlestar arm segments! Ophiuria sp. I found the first one and was so excited...and then I found an even longer segment! 6mm The first segment I found (thanks to @erose for the ID) Next favorite - Floating Crinoids! Roveacrinus signatus 3mm Another one, but with more goblet shape : Roveacrinus signatus 3mm Plotocrinus spiculatus 2mm Not completely sure about the ID on this one. I think it's Drepanocrinus paroculus 3mm Some little tiny teeth. I did find ONE broken shark tooth, just the blade, but it's my first Shark Tooth from Shoal Creek! My most exciting tooth find - Ray Pseudohypolophus ellipsis 3mm A couple of unknown Fish Teeth 2mm Not sure if this is a denticle or tooth: 3mm A couple of little vertebrae: 4mm Some funky little Foraminifera: Nodosaria sp. Size 4mm 3mm An interesting chunk of what I think is Bryozoan. Size 2mm And finally, some little gastropods. 6mm I can't wait to go back and get another baggie full of matrix!

What hand tools are used to separate Sub MM (even UM) fossils....
OregonFossil posted a topic in Micro-paleontology
So how do you "capture the UM size fossils and place them on another slide"? I am thinking of micro fossils less than 1mm. I would like isolate and move to another slide specific specimens. Dental tools are way too big. Do you make your own out of extremly fine wire or what? Sources? -
Took a little trip to Lake Jacksboro spillway and concentrated on the microzone hoping to find some of the little goniatites and nautiloids. Only found a couple that were "big enough" to see , but once I went through my bag of matrix, I was happy to have found quite a few of the microfauna! A few I am not sure of the ID so any help is appreciated! All of these are 1/8 to 1/16 inch Goniatite Peritrochia sp. Nautiloid Gastrioceras listeri same as above, I think Goniatite Prouddenites bosei Goniatite Cardiella ganti Goniatite Pronorites sp. Not sure what this one is: Nor this one. A few other nice little finds I think this is a shark spine: A scaphopod Plagioglypta sp. a tiny whole Rostroconch (had only found half ones prior) and a Trilobite spine!
