Scleromochlus taylori was a small, slender animal, graceful on long hind legs, possibly capable of both bipedal and quadrupedal locomotion; it was fairly small, measuring about 186 mm in length, or about 4.3 inches, of which 34.4 mm was head (about 1/5 body length), and hailed from the Upper Triassic (upper Carnian) Lossiemouth Formation in Lossiemouth, just north of Elgin in northern Morayshire, Scotland (UK). The holotype is BMNH R3556, a partial skeleton preserved in negative form (only as impressions) on sandstone, with a partial, damaged skull and missing distal tail.
