Nanosaurus or Nanosaurus agilis is known from material from all parts of the body, including two good skeletons, although the skull is still poorly known. It was a small dinosaur, 6.6 ft. or less in length and 22 lbs. or less in weight.

Nanosaurus or Nanosaurus agilis was a bipedal dinosaur with short forelimbs and long hind limbs with large processes for muscle attachments. The hands were short and broad with short fingers.

The dinosaurs head was small. Nanosaurus or  Nanosaurus agilis had small leaf-shaped cheek teeth (triangular and with small ridges and denticles lining the front and back edges), and premaxillary teeth with less ornamentation.

Like several other neornithischian dinosaurs, such as Hypsilophodon, Thescelosaurus, and Talenkauen, Nanosaurus or Nanosaurus agilis had thin plates lying along the ribs. Called intercostal plates, these structures were cartilaginous in origin.

Nanosaurus or Nanosaurus agilis attracted little professional attention until the 1970s and 1980s, when Peter Galton reviewed many the “hypsilophodonts” in a series of papers. In 1973, he and Jim Jensen described a partial skeleton (BYU ESM 163 as of Galton, 2007) missing the head, hands, and tail as Nanosaurus?

Rex, which had been damaged by other collectors prior to description. By 1977, he had concluded that Nanosaurus or  Nanosaurus agilis was quite different from N. rex and the new skeleton, and coined Othnielia for the latter species.

The paper (primarily concerning the transcontinental nature of Dryosaurus) considered Laosaurus consors and L. gracilis synonyms of O. rex without elaboration, and considered L. celer an invalid nomen nudum.
