Eocursor parvus

(Little dawn runner)Etymology
Eocursor is derived from the Greek "eos" (dawn) and the Latin "cursor" (runner), referring to its early occurrence and apparent locomotory abilities.
The species epithet, parvus, means "little" in Latin.
Discovery
The remains of Eocursor were discovered in the Upper Elliot Formation in a "donga" (gully) at Damplaats Farm, Ladybrand District, Free State, Republic of South Africa, in 1993. The holotype (SAM-PK-K8025, housed at Iziko South African Museum) is a partial skeleton including material from the lower jaw, arms, hands, pelvis, legs and feet, and vertebrae from the neck, back, hip and tail. All in all, it's around 25% complete.
