trilobites in NE OK

[Knowles]

stumbled onto a bed of these tihs week. brought a few of the complete ones out for show. Do they have much value? From what ive read online, their a rare trilobite and even more so due to lacation. 2guys fossils list some from kansas that are the same. any input is appreciated, im a head hunter, therse were an accident....

Hi Rick
I assume those are Ditomopyge decurata from Permian deposits. If so, you're correct that Permian trilobites are kinda' scarce. Proetida (of which Ditomopyge was part) was the only order of trilobites to survive into the Permian before these animals became extinct. I think you could expect nice intact specimens, in or out of matrix, to realise about 60 Dollars. About half that for negative impressions or partials. Multiples on plates with nice geometry would fetch much higher prices. Size doesn't matter that much... this was a small species anyway.
In general, these days the market doesn't really reflect additional rarity arising from an unusual location. Unless you happen to find a buyer who specialises in collecting Oklahoma material.
Hope that helps, but please treat this as guidance.

I do believe they are Ditomopyge Scitula and they are from the Pennsylvanian.
Much older than Permian and not so rare. The area around NE Ok is Missipian and Pennsylvanian.
With just the pygidium as a specimen it's just an educated guess. Need a complete specimen to be sure.
The Delaria antigua is the specimen Roger is thinking of, it is from the Permian and yes it is rare.
The ones you have are not Delaria.
Sorry but your specimens are worth about 2-4 dollars at the fossil shows.  
The Ditomopyge are commonly found in the immediate area where the Paladin Marrowensis "My Avitar" are found.
