minnbuckeye Posted February 22 Share Posted February 22 Posts of my trip to Oklahoma this week had some unidentified fossils shown. Hope was that someone would mention the identity of the specimens. Since no one did, today I am attaching photos of unknowns from the Viola Formation, Ordovician found south of Sulphur, OK. Maybe @crinus is knowledgeable! Could they be something like Evactinopora? 4 Link to comment Share on other sites More sharing options...
Mochaccino Posted February 22 Share Posted February 22 This looks like a plate from a Rhombiferan cystoid. No idea on the spiky ones but probably some sort of echinoderm plate. Evactinopora is Mississippian I believe. 1 2 Link to comment Share on other sites More sharing options...
connorp Posted February 22 Share Posted February 22 Possibly plates from the crinoid Colpodecrinus. Below are examples from the Bromide Formation which underlies the Viola. Plate 22 from https://kuscholarworks.ku.edu/handle/1808/3841. 4 Link to comment Share on other sites More sharing options...
