Eostyloceros hezhengensis

Diagnosis. A large-sized muntjak with pedicles in parallel with the sagittal axis of the skull. Between the two frontal ridges, the front bone is strongly concave and the sagittal suture forms a robust ridge. The lacrymal fossae are very large. The anterior orbital rim is above the M 2 / M 3 boundary. The pedicle is short, cylindrical, robust, and extends posteriorly from the rear of the orbit. The shedding plane of the burr forms an angle of about 70 ° medially with the longitudinal axis of the pedicle. The burr consists of a series of knobby tubercles. The anterior and posterior branches arise and diverge at an angle of 30 ° from the burr, with a U-shaped fork. Both of them have many deep furrows and high edges on their surfaces. The posterior branch is relatively long, and its tip is strongly curved posteriorly and medially. The anterior branch is straight and long, about half as long as the posterior branch, and it is situated anteromedially from the posterior branch. The posterior branch is lateromedially compressed, and the anterior branch has a circular cross section.
