Myledaphus araucanus sp. nov., SGO.PV.6600, holotype. Pelluhue, central Chile. Quiriquina Formation, lower upper Maastrichtian. A, Partial, articulated tooth pavement. Diaclases are indicated for teeth which were naturally broken during the burial; B, sectioned tooth sample. SGO.PV.6598. Two associated teeth. Algarrobo, central Chile. Estratos de Quebrada Municipalidad unit, lower Maastrichtian. C, E, teeth in lateral view; D, F, teeth in occlusal view. SGO.PV.6732. One isolated tooth associated with two dermal denticles, likely referable to the same specimen. G, lateral view of the tooth; H, I, dorsal view of the dermal denticles; J, lateral view of one of the dermal denticles. Scale bar equals 5 mm in all cases except B, equals 1 mm. © Otero (2019)
