Abstract Details

2019, Master of Sciences, Case Western Reserve University, Biology.
Hemihegetotherium trilobus is a hegetotheriine notoungulate from the middle Miocene (13-12 Ma) Quebrada Honda Fauna of Southern Bolivia. H. trilobus is a herbivore common at Quebrada Honda with hypselodont cheek teeth suited to consuming abrasive plant material either graze or browse. Herein, I describe the fore- and hindlimb osteology of H. trilobus based on a number of well preserved specimens from Quebrada Honda. H. trilobus exhibits digitigrade limbs similar to other typotheres with tetradactyl manus and pes including the absence of digit I and reduction of digit V typical of hegetotheriids. The ungual phalanges, however are more similar to Mesotheriidae than pachyrukhine hegetotheriids. With a mass estimated 10kg, H. trilobus exhibits postcranial features consistent with both cursorial and fossorial capabilities.
