Yorktown formation microfossils from Chippokes State Park in Virginia
MiguelM posted a topic in Micro-paleontology
Hello, Some friends and I went to Chippokes State Park in Virginia last week. The park is beautiful, and going down to the beach was very nice. We ended up settling at a sand bar formed at the mouth of the College Run creek. Although, we did not find anything too remarkable at first sight - other than lots of fossil oyster and clam shells - after sitting down for a bit we found our first shark tooth. With renewed hopes we kept scouring the area and found a couple more smaller ones - no meg big or small sadly... I did decide to bring with me a gallon Ziploc bag half full of material to look at under the microscope. So far, like halfway through the bag, this is what I've found that has called my attention. Smaller marks are mm on the scalebar. Just a couple of questions or observations: - I think the crab claws are not fossils, right? - Are these guys urchin spines? - What do you think this is? It has some symmetry, but I am not sure if fossil or fancy looking (little) rock. - Tiny tiny shark tooth, but what species? - I have no clue what these might be If there's anything else that catches your eye, let me know and I'll take better pics. I really want to start building a good knowledge of the fossils/micro-fossils of the Williamsburg-Norfolk area now that I live here and so far removed from my beloved Peace River. Thanks: Miguel M

Any idea what this tiny fragment could be? Found in a sample containing conodonts and other microfossils.

Very small Cladodont (Falcatidae?) Tooth in Phosphatic Nodule ( Missouri )
Samurai posted a topic in Fossil ID
Location: Missouri Period: Pennsylvanian Formation: Iola Limestone (Muncie Creek Shale Member) Hello once again! Today I have a fossil tooth that I happened to have seen while going through my old phosphatic nodules from Muncie Creek and was wondering if anyone could identify it further than a Cladodont tooth. I have googled images of Cladodont teeth and believe it to possible be a tooth belonging to Falcatidae, but what do you think? It resembles a few of these teeth on the chart below in size and form, hence why i'm making the guess of it being a Falcatid even though my tooth has very slight differences in lengths of each cusplet. I will note that my specimen seems to have 6 cusps total, while the specimens below that it most resembles has 5. Here is the size in mm. The last thing I wanted to note is that it might be next to possible coprolitic material, although it's hard to tell as coprolites in these nodules looks very similar to just a phosphate center, although if you find inclusions its almost guaranteed. Example of an obvious coprolite and a not so obvious coprolite from these nodules.

Small, freshwater shark teeth. -
I recently collected from the Drakes formation on the west side of the Jessamine dome. I've been dissolving rocks, rinsing and then baking for about ten minutes in an old toaster oven. This is my outdoor laboratory. Here are some fossils. Thanks for looking.

Dimetrodon spines have a unique shape: ^ Brink et al. (2019) Many bones in the matrix I have appear to have bite marks - parallel grooves in bone. My amateur guess is that these are scavenging marks from a Dimetrodon carcass that got washed into a river and got chomped by Xenacanthid sharks (there certainly are other possibilities).-

I'm convinced it's a tooth, but not sure what kind. More images here. -
Hi y'all, I was thinking again about some Permian reptile teeth, I've seen them referred to online as 'parareptile,' but would like collective and/or professional insight. They are pretty distinctive, with a smooth labial face, and a striated lingual face. These are all from Waurika, OK (Wellington fm, Lower Permian). I have several examples, but they're not much different from these two. @jdp @dinodigger 3.5 mm tall: 2 mm tall: They vaguely remind me of a Caseid tooth, which has the same character of the striations/no striations (or I at least think this one is Caseid...). ^ Reisz (2019)

Rhinobatos teeth are so small they make me angry Here you see a dozen guitar fish teeth sitting on the face of a dime! The largest is a bit under 1 mm tall. R. incertus has a pointed crown, R. caseiri has no point.-

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:
