Short summary
Here we describe a large specimen of the Paleozoic dissorophid amphibian Cacops woehri from the Fort Sill locality in Oklahoma, which was previously only known from a partial juvenile skull. The new data show that, in contrast to the closely related species C. morrisi, C. woehri underwent only subtle changes in skull morphology in late ontogeny, which indicates different functional demands possibly associated with a different ecology.
