Permian Reptile Vertebra ID


BigJim2500

Recommended Posts

Hi, looking for some thoughts on identification of a fossil I bought a while ago. 

This is a fairly well preserved vertebra from an early reptile of some kind. Unfortunately I lost the original label for it so all I can say is that it’s from 300-250 mya, and from a formation in Oklahoma or Texas. I’m not very experienced with Permian stuff, so I’m not sure where to begin. Thanks for any help!

Trilobites do not have jawbones. They are arthropods. Invertebrates do not have bones.

Yes I hate it when this happens. It has happened to me too a couple of time . I now add the info in a notebook too. Because of my dyslexia labelling is very hard work.  @Uncle Siphuncle He maybe able to help as he has collected at Richards Spur quarry.

I collected that quarry one whole day 15 years ago, haha.  With a vert that big, I’d start w comparing to Eryops and Dimetrodon.

Yes, which is why your declarative statement that it was obviously a "trilobite jawbone" made no sense. When uncertain, you may wish to use hedging words. For example: "it may be a trilobite", "it looks like a trilobite", or "might it be a trilobite?" Words such as clearly, evidently, and obviously signify absolute certainty.

Or, if joking, at least make sure to use the emoticons to express your humor more openly.

I think even a 3 year old would know that was not a trilobite. Its bigger on its own than most trilobites. But yes, by saying obviously I was being sarcastic. Everyone knows trilobites don't even have bones.

Yeah, I thought we were all on the same page about that one. I guess it might not be as funny as I thought it was. Sorry guys.

Don’t worry about the joke, it’s all good. To get back on the subject, I have some beers that have been confirmed as dimetrodon milleri, and they aren’t very similar. It looks sort of like eryops, but not enough for me t confirm (although I’m not very experienced with that material). It is fairly well preserved, so I feel like a genus identification is possible, but I’m a bit stuck. Hmm...

VERTS, not beers, that was autocorrect.

Nah it was a decent joke, but Tim is right in saying that the emoticons should be used when making a joke like this. If you had written "Obviously a trilobite jawbone :P" it would've been much clearer. And not everyone knows that trilobites don't have bones; most people on the planet have never heard of trilobites, and many others simply deny they ever existed. ;)

This is definitely not Dimetrodon or Eryops. The swollen neural arch and relatively small vertebral centrum fits pretty well with either a seymouriid (maybe Seymouria) or diadectid (Maybe Diadectes). I think the limnoscelid Limnoscelis might be a good match, actually.

 

Any idea on the locality?

Unfortunately even with the label I couldn’t give you a locality down to formation. The dealer wasn’t too sure himself. Now that I recall, I’m pretty sure it is from somewhere specifically in Oklahoma. I’ll definitely check on the species you suggested for comparisons. Hopefully knowing the state can do something to narrow the time frame.

Unfortunately the sequence in Oklahoma contains much of the Late Carboniferous and nearly the entire Early Permian sequence right up through the earliest parts of the Middle Permian.

 

Preservation seems consistent with Waurika but it could also potentially be Fort Sill. There's a few other places it could be from.

Ok, serious new development on this, I found the label! The sight is still left only as Oklahoma, but the date is 225 mya. So that sort of changes things. With this in mind, any new thoughts from anyone?
