Corcorania has a semioval head shield with rounded
posterolateral corners and a somewhat truncated appearance from lateral view. Three slightly curved anterior spines extend from the margin of this shield, with the more lateral two being longest. The posterior ventral part of the shield has strong projections, likely for anchoring soft tissue. The trunk consists of seven segments decreasing in size posteriorly. The posterior shield is slightly smaller than the anterior with a subtriangular shape. Appendages are rarely preserved, with only a few known. Possible
furcal rami are known from some specimens however these are unclear. A spine protruding from beneath the right side of the first trunk segment is the only evidence of appendages, however several disassociated ones are known. The most common type of appendage is semicircular with three curved spines on its rounded margin, although a spinier and more rectangular type is also known. == Etymology ==
