Redeiscription and Phylogenetic Analysis of Materials Associated with “Captorhinikos” chozaensis

SMSU Event Center BC

“Captorhinikos” chozaensis is a multipletooth-rowed captorhinid reptile from the Lower Permian Clear Fork Group, undivided formation. Upon reexamination of the materials associated with the species from both the Chicago Field Museum of Natural History, and the Smithsonian United States National Museum, I reaffirm their affinity and collective identity as a valid taxon. “Captorhinikos” chozaensis does not, however, belong with either of the two members of its genus, C. valensis or “C.” parvus, instead occupying its own branch on the phylogenetic tree of the Captorhinidae. This conclusion is based in strong results from a combined phylogenetic parsimony analysis combined with an analytical apomorphy analysis. I then conclude the current designation “Captorhinikos” chozaensis to be a nomen ambiguum.
