It was about a metre long. Its back was [[armour]]ed, and it is placed in the [[Thyreophora]] with the other armoured dinosaurs. It was one of the earliest members of this group, and the most [[basal]] (primitive) form so far known. Its closest relatives may have been ''[[Emausaurus]]'' and ''[[Scelidosaurus]]''. These, and the larger armoured dinosaurs ''[[Ankylosaurus]]'', ''[[Stegosaurus]]'' and ''[[Huayangosaurus]]'', were all quadrupedal. The lightly built bipedal ''Scutellosaurus'' is similar in form to the ancestral dinosaurs, which were bipedal.<ref>The dinosaurs were ancestrally bipedal: all the earliest ones known were bipedal. That means the transition from a quadrupedal [[archosaur]] reptile to a bipedal form took place before the dinosaurs evolved. The heavier dinosaurs later became quadrupedal again. This was, for them, a secondary or [[derived (biology)|derived]] condition.</ref> ==Description== ''Scutellosaurus'' was around {{convert|1.2|m|ft}} long,<ref name=EoDP>{{cite book |editor=Palmer, D.|year=1999 |title= The Marshall Illustrated Encyclopedia of Dinosaurs and Prehistoric Animals|url=https://archive.org/details/illustratedencyc0000unse_y8e7|publisher= Marshall Editions|location=London|pages= 134–135|isbn= 1-84028-152-9}}</ref> {{convert|50|cm|in}} tall at the hips, and weighed {{convert|10|kg|lb}}.
