Myledaphus bipartitus

Myledaphus is an extinct genus of guitarfish. It currently contains four valid species found in North America, South America, and Central Asia. It is confirmed to have lived during the Late Cretaceous, with possible occurrences in the Paleocene and early Eocene. While the genus is mostly known from teeth, two partial skeletons of M. bipartitus have been found in the Dinosaur Park Formation of Alberta.
