The type species, B. beaumonti, has been found in Samos and Pikermi, both in Greece, and in Çobanpinar, Turkey. Juvenile specimens of B. beaumonti are similar in size to modern adultstriped hyenas, and adults may have been larger. The weight of B. beaumonti has been roughly estimated at around 40 kilograms (88 pounds).
Belbus djurabensis
B. djurabensis was discovered in Toros-Menalla in the Djurab desert of Chad. It is smaller than B. beaumonti. B. djurabensis has a smaller talonid on its m1 molar and a smaller M1 relative to the size of its P4 premolar than the type species. The premolars of B. djurabensis, especially the p3, are larger than those of B. beaumonti. The specific name of B. djurabensis is derived from the name of the Djurab desert.
