Description
Thin bivalve shell with slight umbo, concentrically striate, ?ribeiroiid or Bivalvia. [Refers to type-species and Modialocaris only. Other Lower Ordovician species referred to this genus are based on elongate carapaces resembling Hymenocaris. Further knowledge of these is needed before establishing a separate genus. The body segments shown on PEACH'S restoration of M odioloearis are imaginary; the holotype shows only a fracture plane.]
