Description
Original diagnose after Claeson et al. (2013) p. 1023 [19627]: Platyrhinid batoid of moderate size. Unlike Platyrhina (Müller and Henle 1838) in possessing a more medially placed anterior horn on the nasal capsule and a longer chondrocranium between the nasal capsules and the otic capsules. Unlike Platyrhinoidis (Garman, 1881) in possessing a small, circular posterior dorsal roof foramen, instead of an anteroposteriorly broad and figure-eight-shaped fontanelle, and in possessing slender, laterally wide mandibular arch cartilages. Possesses short, tapered snout; plate-like antorbital cartilage; dorsal groundmass denticles are smooth and arrowhead-shaped; jaws gracile and straight; single anterior fontanelle; first complete vertebral centrum located extremely posterior along the length of the synarcual; and postpelvic processes present.
