Like all sauropods, Nigersaurus was a quadruped with a small head, thick hind legs, and a prominent tail. Among that clade, Nigersaurus was fairly small, with a body length of only 9 m (30 ft) and a femur reaching only 1 m (3 ft 3 in); it may have weighed around 1.9–4 t (2.1–4.4 short tons), comparable to a modern elephant.

Ornithischia (/ ˌ ɔːr n ə ˈ θ ɪ s k i. ə /) is an extinct clade of mainly herbivorous dinosaurs characterized by a pelvic structure superficially similar to that of birds. [6] The name Ornithischia, or "bird-hipped", reflects this similarity and is derived from the Greek stem ornith-(ὀρνιθ-), meaning "bird", and ischion (ἴσχιον), [a] meaning "hip". [7]
