Ovatoryctocara granulata is a species of corynexochid trilobite from the Cambrian. Its first appearance is one of the proposals for the base of Wuliuan (The other proposal havign beenOryctocephalus indicus).[1] The species was first formally described by the Russian paleontologist N.Ye. Tchernysheva in 1962.[2]
