Homalostylops parvus Ameghino (1897)

A mandibular fragment with m1–2 of a small notostylopid was collected in La Barda (LIEB-PV 1621). By its size and the presence of an accessory cusp in the middle of the metalophid, it is certainly referred to Homalostylops parvus , one of the few species recorded for both the Vacan and Barrancan subages. A left mandibular fragment with m2 (LIEB-PV 1622), also collected in La Barda, is referable to this species.
