Scientific synonyms

Cervus obscurus Azzaroli, 1953 o
Megaloceros obscurus (Azzaroli, 1953)

Temporal range:Middle Pleistocene
Diagnosis (Croitor, 2006): The body size is very large. The antler base is set obliquely with respect to the burr plane. The subbasal tine is long, strong, cylindrical, and situated very close to the burr. The dorsal tine is situated on the upper (medial) side of the beam, very long and compressed in the dorso-ventral direction in its distal part. The middle tine appears in fully mature individuals and is set on the anterior side of the beam. The posterior tine is developed in adult individuals. Antler beam is sharply bent in the area of posterior tine. Distal portion of antlers is not palmed. Pedicles are cylindrical, with normal orientation. The praeorbital fossae are large and deep. The ethmoidal openings are large. The anterior part of maxillary bones is moderately extended. The lingual wall of P2 is cleft. Lower fourth premolar (P4) is molarised.
AZZAROLI (1953) described “Cervus” obscurus as a species with uncertain systematical position. The species description was based on a series of syntypes: a fragment of antler M2321 (NHML) (AZZAROLI 1953: 74, fig. 42), an antler tine M6421(NHML) (ibidem, fig. 43); a basal fragment of antler with pedicle and frontal bone M18482 (NHML) (ibidem: 75, fig. 44a-b). The original description of species did not provide an explicitly designated diagnosis.
