Orthrozanclus (from Greek + ( + ), "dawn scythe") is a genus of sea creatures known from two species, O. reburrus from the Middle Cambrian (~) Burgess Shale and O. elongata from Early Cambrian (~) Maotianshan Shales. Animals in this genus were one to two centimeters long, with spikes protruding from their armored bodies. The placement of this genus into a specific family is not universally accepted.
==History of discovery== Jean-Bernard Caron and Donald A. Jackson found a specimen in the Burgess Shale and in 2006 referred to it as "scleritomorph C" without a detailed description. In 2007 Caron and Simon Conway Morris published a description and named the fossil Orthrozanclus reburrus. The genus name means "Dawn scythe" and derives from Greek, with the species name meaning "bristling hair" in Latin.
