Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L. Pinder and A. P. Grosse 1991 | Blastocerus dichotomus (Fig. 1) is the largest of the South American deer (Cabrera and Yepes, 1940). A straight basicranium and the antlers distinguish Blastocerus from the other Odocoileini. Antlers of adult marsh deer have four tines, which are never pointed inward as in Odocoileus (Fig. 2). The main beam bifurcates near the base, and each prong is again bifurcated, a condition rarely seen in Ozotoceros (Groves and Grubb, 1987; Jack- son, 1987). The legs of adult Blastocerus are black up to the radius or tibia and pelage of the young is unspotted. The two toes of the hoof are bound by a strong membrane, and can be spread up to 10 cm apart. No other South American deer attains such interdigital amplitude (Hofman et al., 1976). |
