Abstract	For the first time, fossils of unquestionable eurypterid origin are documented from the renowned Lower Devonian Hunsrück Slate Lagerstätte in southwestern Germany. The gnathobase of a coxal plate and a body segment can be attributed to pterygotid eurypterids, probably to Jaekelopterus rhenaniae. These body parts from the Hunsrück Slate once more confirm the extraordinary large size that could be attained by this Rhenish eurypterid. Based on the usual occurrence in marine–terrestrial transitional facies elsewhere in the Rhenish Devonian, rareness in the Hunsrück Slate, and poor preservation, the Hunsrück Slate pterygotid remains are most probably allochthonous, and eurypterids are considered nongenuine elements of the ‘Hunsrück Slate biota.Erstmals werden zweifelsfrei als Eurypteridenreste bestimmbare Fossilien aus dem unterdevonischen Hunsrückschiefer dokumentiert. Die Gnathobasis einer Coxalplatte und ein Körpersegment lassen sich den pterygotiden Eurypteriden zuschreiben, mit einiger Wahrscheinlichkeit der Art Jaekelopterus rhenaniae. Die Maße der vorliegenden Reste unterstreichen einmal mehr die außergewöhnliche Körpergröße, die ausgewachsene Exemplare dieser rheinischen Eurypteridenart erreichen konnten. Angesichts des weit häufigeren Auftretens rheinischer, pterygotider Eurypteriden in marin-terrestrischer Übergangsfazies, ihrer großen Seltenheit und relativ schlechten Erhaltung im Hunsrückschiefer sind diese Reste wahrscheinlich allochthon. Eurypteriden können deshalb nicht als originärer Bestandteil der ‚Hunsrückschiefer-Lebewelt‘ im engeren Sinne gelten.
