Size of the Dinosaur
Efraasia was originally considered to be a small animal, based on fragmentary remains that could not be assembled extremely well, but it was later realized that the animal was much larger than believed. The estimated larger size is approximately 6.5m (21 ft). The dinosaur was still small for its size, but by small we mean gracile and lightly built rather than short or thin. The gracile hands and feet of the animal could be used to imply facultative quadrupedalism, though this is also implied by the fact that may other very early sauropodomorphs were known to be capable of moving bipedally and quadrupedally equally well. Poor pronation of the forearm, as some have hypothesized, may have limited Efraasia as an entirely bipedal dinosaur. Its gracile hands and digits were probably quite capable of grasping food items (and predatory animals and intraspecific competitors) which could then enable it to better survive its environment by adapting its diet (and defending itself more capably).
