Abstract: The syntype specimens of the aetosaur Episcoposaurus horridus Cope, 1887, are from the type locality of Typothorax coccinarum Cope, 1875, in the Painted Desert Member of the Petrified Forest Formation, Chinle Group at Cerro Blanco, Rio Arriba County, New Mexico. The syntypes of E. horridus are topotypes of T. coccinarum, and some probably represent the same individual as the lectotype of T. coccinarum. E. horridus is a junior subjective synonym of T. coccinarum, and we restrict the lectotype of E. horridus to a single caudal dorsal paramedian osteoderm. The topotypes of T. coccinarum provide a more complete picture of the anatomy of the species and further confirm its distinctiveness from T. antiquum.
