hokietech96 Posted October 28, 2020 Share Posted October 28, 2020 I took a break from Lee Creek and Bone Valley matrix and worked on some Waurika matrix. This matrix was so much fun to go through. Every was a first for my collection! I believe that I identified everything correctly but if you see anything that is wrong please let me know. I will be adding more to this post in the near future.... @sharkdoctor Thought you would enjoy the pictures! Dimetrodon limbatus claw 5MM: @Bobby Rico @dinodigger From previous posts I have read, this is right up your alley. Diplocaulus Jaw 2MM: Shark tooth I have not found anything that shows this type of tooth for this location. I think it might be a contaminant? @Al Dente How cool is this 2MM piece of matrix with a Barbclabornia luederensis tooth in it: Orthocanthus platypternus: Tons of different shaped Orthocanth shark denticles: This one looks like two that are still attached together More variety of teeth pictures to come! 8 Link to comment Share on other sites More sharing options...
sharkdoctor Posted October 28, 2020 Share Posted October 28, 2020 Great finds! Looks like you've been having a blast with that material. Those denticles are gnarly! 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted October 28, 2020 Share Posted October 28, 2020 Excellent stuff here! Permian material is so intriguing!

The delicate fluting on the teeth looks a lot like acleistorhinid parareptiles, perhaps something like Delorhynchus. 3 Link to comment Share on other sites More sharing options...

This is new material for me so thank you so much with the ID help! What should I being looking for in the characteristics for Diplocaulus? Link to comment Share on other sites More sharing options...
jdp Posted October 28, 2020 Share Posted October 28, 2020 Diplocaulus has small simple conical teeth that are all the same size, a jaw that is extremely deep compared to the tiny teeth, and the surface of the bone has a really conspicuous golf ball texture. Most of the stuff called "Diplocaulus" on the internet just isn't, which is strange given how common Diplocaulus is at many Permian sites. Link to comment Share on other sites More sharing options...

I have more matrix to go through so hopefully I find one. Link to comment Share on other sites More sharing options...

I picked up some Ryan formation Permian microfossil gravel a little while back and started to dig in and wondered if you had a link to a website, paper or even a good old fashioned book that helps with IDs with this material. @hokietech96 great pictures.

jdp Posted November 6, 2020 Share Posted November 6, 2020 I don't, sorry. My experience comes from working with research collections of early Permian vertebrate fossils for several decades. 1 Link to comment Share on other sites More sharing options...

hokietech96 Posted November 24, 2020 Author Share Posted November 24, 2020 It has been a bit of time since I posted. Just wanted to add some additional teeth that I have found in the matrix. Everything is 3-5MM. Any corrections with my ID is much appreciated! @jdp #1 Trimerorachis insignis #2 Trimerorachis insignis (front) #2 Trimerorachis insignis (back) #3 Ophiacodon retroversa tooth?? #4 Eryops megacephalus (front) #4 Eryops megacephalus (back) #5 Beat up Dimetrodon tooth (front) #5 Beat up Dimetrodon tooth (back) 3 Link to comment Share on other sites More sharing options...

ThePhysicist Posted November 24, 2020 Share Posted November 24, 2020 I'm still learning to id permian material, so these may not be accurate. Regardless, very cool teeth! Some of the teeth that look like 1,2 found in this matrix may actually be fish. See this thread: 3,4 look like xenacanthid/orthacanthid shark cusps. I think eryops and ophiacodon don't have ziphodont teeth. 2 "Argumentation cannot suffice for the discovery of new work, since the subtlety of Nature is greater many times than the subtlety of argument." - Carl Sagan "I was born not knowing and have had only a little time to change that here and there." - Richard Feynman Collections: Hell Creek Microsite | Hell Creek/Lance | Dinosaurs | Sharks | Squamates | Post Oak Creek | North Sulphur River | Lee Creek | Aguja | Permian | Devonian | Triassic | Harding Sandstone Instagram: @thephysicist_tff Link to comment Share on other sites More sharing options...
