Willwerathia is a genus of Devonian arthropod. It is sometimes classified as synziphosurine,[1][2] a paraphyletic group of horseshoe crab-like fossil chelicerate arthropods,[2] while some studies compare its morphology to an artiopod.[3][4] Willwerathia known only by one species, Willwerathia laticeps, discovered in deposits of the Devonian period from the Klerf Formation, in the Rhenish Slate Mountains of Germany.[1][5]
