About Bunobrontops
Bunobrontops (lit. 'mound thunder face') is an extinct genus of brontothere that lived in Southeast Asia during the Middle Eocene, in the Sharamurunian land mammal age. The genus contains a single species, B. savagei, known from isolated molars found in the Pondaung Formation of Myanmar.
Bunobrontops has been estimated to have reached a weight of about half a tonne (1,100 lbs). Despite the poor fossil material, Bunobrontops is easily distinguished from other brontotheres by a unique combination of primitive and advanced characteristics in the molars. This unique combination represents an important morphological link between early brontotheres such as Eotitanops and Palaeosyops, and more derived forms.
