Moselopterus is a genus of prehistoric eurypterid from the Devonian period in Europe. The genus contains two species, M. ancylotelson from Germany and M. lancmani from Latvia.
A third species, M. elongatus, from the same deposits as M. ancylotelson, was previously recognized.Dunlop, J. A., Penney, D. & Jekel, D. 2015. A summary list of fossil spiders and their relatives. In World Spider Catalog. Natural History Museum Bern, online at http://wsc.nmbe.ch, version 16.0 http://www.wsc.nmbe.ch/resources/fossils/Fossils16.0.pdf (PDF). M. elongatus differs from M. ancylotelson only in its larger size and more elongated body, and likely represents an older ontogenetic stage of the same species.
