This species was larger than the modern nilgai. Its horn cores are slightly closer to the orbits compared to its living relative, with their inner keel further inward and more to the front. Their teeth are
hypsodont, indicating that it was a grazer. Fossils of
B. namadicus are known from the
Siwaliks and are found in association with other large herbivores such as
Equus sivalensis,
Stegodon,
rhinoceroses, and the
straight-tusked elephant. The presence of
B. namadicus and these other large herbivores indicate that the environment of the area at the time was dominated by open grassland. ==References==
