Masrasector is an extinct genus of hyainailouroid hyaenodont that lived in Afro-Arabia from the Bartonian to the Rupelian stages of the Eocene and Oligocene epochs.

Palaeobiology

Locomotion

Discriminant function analysis performed on the humeri of Masrasector nananubis and other hyaenodonts has found that M. nananubis was fully terrestrial and was likely a fast runner.
