Melbournopterus is a genus of prehistoric chelicerate or brachiopod, known from the Upper Silurian of Australia. It is of uncertain taxonomic placement within the subphylum Chelicerata.[1] Lamsdell, Percival and Poschmann (2013) argued that Melbournopterus crossotus is not a chelicerate at all, and interpreted its type specimen as the dorsal valve of a craniate brachiopod.[2]
Description
If Melbournopterus is a chelicerate, it is distinguished by its prosoma (head), which is bell-shaped and emarginate in front, with subrectangular compound eyes located posteriorly on the prosoma, which strongly converge anteriorly. It was small in size, and its abdomen and appendages are unknown.[3]
