''Sarotrocercus'' is a small Cambrian organism known from Burgess shale-type localities, reaching a centimetre or two in length. It was pelagic and swam on its back. It may lie in the arthropod crown group, and a recent study has revised some points of its original description. == Morphology == It had a head shield followed by a body of nine segments and a caudal tip featuring a series of spines on the end. A pair of big eyes at the end of stalks emerged from the front of the shield. The head bore a pair of sturdy appendages that ended in a bidentate segment. Ten pairs of appendages with an elongated structure of comb-shaped, probably gill branches, are attached to the at the head segment (one pair) and the body segments (nine pairs).
