During field and laboratory investigation of the phosphate nodules that are eroding from the Excello Shale of the Senora Formation, Cabaniss Group, Desmoinesian, of Middle Pennsylvanian age of Rogers County in northeastern Oklahoma has produced numerous vertebrate, invertebrate, and plant fossils. The vertebrate material recovered include the dermal denticles of Petrodus patelliformis and Listracanthus hystrix, along with teeth of Cladodus occidentals, Caseodus eatoni, Edestus sp, Lisgodus serratus, and a spine from the spine-brush complex of Stethacanthus sp. Previously, the only known vertebrates reported from the Excello Shale of Oklahoma were Edestus and Petrodus. This report thus increases the number of known vertebrates from the Excello Shale of northeastern Oklahoma.
