Earlier this month I got the opportunity to return to one of my Permian fossil sites that I haven't visited since around April. The site is located in McClain County in central Oklahoma south of OKC. According to a geological map the majority of the area consists of the Wellington Formation, however the bottom of the exposed area is shown to be apart of the Stillwater Formation. According to scientific publications the only fossil producing layer is mentioned as belonging to the Wolfcamp (296.4 to 268 Ma) particularly the Gearyan strata. I've spent multiple trips earlier this year searching th

Identification: This tooth was found in processed microfossil matrix from Waurika, OK, USA. Reptile remains in general are very uncommon, so if you think you've found many pieces of Dimetrodon teeth, you're likely mistaking many Orthacanth shark cusps. Orthacanth shark enamel is smooth, and the serrations are quite prominent compared to those on Dimetrodon which are finer. Dimetrodon enamel is not smooth, as seen on this one. Dimetrodon crowns are also broader. Shark cusps broken at the foot of the crown also flare out, where reptile teeth do not. Were this crown complete, you would also not

From the album: Permian
Dimetrodon sp. Wellington/Ryan Fm., Waurika, OK, USA Post-canine/posterior tooth This tooth is likely from D. limbatus, given the locality and presence of serrations: https://www.nature.com/articles/ncomms4269 The same paper also rules out other serrated Sphenacodonts by the enamel ornamentation. Its smaller size could indicate that it's from a juvenile. It differs from the comparatively abundant broken Orthacanth shark tooth cusps in the microfossil matrix (what most people are likely to confuse with): the enamel texture is not smooth, the c -
I’ve just recently sifted through some permian micro matrix from Oklahoma and I came across this and wasn’t sure if it was anything at all, it was very uniform and sleek so I didn’t immediately assume it was a pebble, it also had that strange split on one end. I’m not even sure if it’s a fossil.

I’ve just found this tooth in some Permian micro matrix from the Wellington formation, it is serrated and around a centimeter long. I’m thinking It’s dimetrodon or some sort of other basal synapsid

I’m sorting through some micro-matrix that is said to be from the “Ryan Formation” however I’m pretty sure that’s just the Wellington formation. I’m looking for some sort of ID on this, It’s about a half centimeter long. My apologies for the poor photo quality, It’s just so tiny and my equipment isn’t good enough

This little bone is around 2 cm long and I’d like to know if this specimen shows any indication towards a species. It was found in a set of micro matrix from the Wellington formation, Oklahoma

This claw was found in some micro-matrix I recently ordered, and I need help with a possible ID, I was thinking possibly Varanops or Edaphosaurus. It is advertised to be from the Ryan formation, now called the Wellington formation. The claw is just shy of one centimeter long

Hi all, I have been going through some of the coprolites in my collection in order to catalog them. I have two different specimens that have fish spine and scale inclusions. They are from Waurika, Oklahoma (Permian). 1. I want to verify that this is a fish spine. If so, could it be from a Xenacanthus?. Does anyone know if Xenacanthus had scales? The coprolite contains numerous scales. Of those that are visible, this is the best preserved. 2. This coprolite has a different type of fish spine. Any idea what type of fish it is from? T

My friend from Florida is a major gourd collector and has items on display in several museums. He cannot resist anything gourd-related so he was compelled to buy this item with a label identifying it as a "petrified gourd" from Ponce City Oklahoma. I see where there are some Permian and Pennsylvanian formations near there so that would eliminate those areas if it were a gourd. I doubt we will be able to know whether it came from the Pleistocene terrace deposits to the east but gourd seems very unlikely anyway. This has a very distinctive look and the preservation seem fairly good s

Had to work a few days in Oklahoma City this week and decided to make a detour on the way home and check out a site that has been mentioned here on the forum. The directions lead you down a dirt road just west of Waurika. It doesn't appear to be an overly visited site just judging by the amount of grass that has been trampled to get in. You could hardly make out the path in the grass. It was mentioned in previous posts that it is not believed to be private but judging that you have to go over an old barbed wire fence and under a new one, my guess is that it is probably private. Seeing no "post

Permian Microfossils from the Wellington Formation
PA Fossil Finder posted a topic in Micro-paleontology
I got some Permian-age microfossil matrix a while ago, and I finished going through the larger stuff a couple days ago. I finally got some good pictures up, so here they are! These are from the Wellington Formation, Jackson County, Oklahoma. Most of the fossils I found were Orthocanthus, but I found a few that may be from amphibians or reptiles. Feel free to correct me in my identifications! I am often wrong, and I would like to be able to label these fossils with confidence and certainty. These, I believe, are Orthocanthus compressus: I think this is an Eryops sp. or similar amphibian t
