From the album: Permian
One of the most common fossils from the Permian (this locality in particular). Unfortunately, they are almost always broken. Of the hundreds of teeth I have, perhaps only a few larger than a couple of mm are mostly complete.-

Eryops teeth are conical (this one bears no carinae, though don't know if that's true for the whole dentition), and often have basal creases.-

From the album: Permian
It's remarkable how much of an ecosystem's diversity can be captured in a space smaller than a matchbox. In this case are the likes of Dimetrodon, Eryops, Archeria, Seymouria et al.-

Some of the famous Texas "red beds" deposited during the Early Permian in streams and rivers, seen near Seymour, TX (member of the Clear Fork Group). Iron in the sand oxidized, giving the stones their eponymous color.-

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).-

the incomplete ventral valve is rather large, about 5cm wide and 8 cm longe, convext, sulcus deep and thin for productus type. It has a kind of triangle shape, with the beak broken and bent down. The beak itself actually look like a normal shaped productus, with costae and concentric lines at right angles forming a grid like network. The concentric lines are missing in other part of the shell, though the tubercles seem to be scatterd every where. I have never seem any thibk like this. Could it just be a drastically deformed productus of some kind, or some individual that got some abnormal growth in its life?

form the late carb/early permian statum in Shanxi, China. The coil does remsemble an evolute nautilus, but it is only 6mm in diameter. I guess ome could not say it is a young nautilus or something, as the conch is hard material , and old part can could not change with growth. too big for fusulina. and not like a gastropod either.

I've been trying to narrow down the ID for bryozoans I've been finding. I'm not sure if they're weathering out of the Bennett shale or from further up. I have collected about 15 of these over the years and found a nice one several days ago. They are characterized by rounded form with flattish uneven bases. Spacing between monticules is about 1 cm regardless of specimen size. The below example is about 8 cm wide at base and 5 cm tall. I can't find it right now so can only show photos. I'll put a link below to my more recent find. All help appreciated!

I know figuring out the IDs of bug wings can be very difficult, but if anyone on here can help I'd greatly appreciate it! I've found these and some others (that I put somewhere I would definitely remember) near Humboldt, Nebraska in the Indian Cave sandstone member of the Towne Formation which puts their age late Pennsylvanian to early Permian. To be completely honest I've wondered if a couple of them might actually be leaf impressions, but I'll let y'all help me figure that out.
