Vertebrate fossils of the Middle Devonian (Eifelian) Mühlenberg Formation in the Bergisches Land, northwestern Germany

Abstract

Vertebrate fossils of the lower Middle Devonian Mühlenberg Formation from the western Bergisches Land (eastern Rhenish Massif) are described. The placoderms are represented by disarticulated plates of coccosteid arthrodires and the acanthodians by several ischnacanthid jaw bones and aMachaeracanthus finspine. The arthrodires are assigned to a new species; a new genus has to be erected if remains of trunk and head shield remains are conspecific.

Kurzfassung

Wirbeltierreste aus dem unteren Mitteldevon des westlichen Bergischen Landes (Rheinisches Schiefergebirge) werden beschrieben. Es handelt sich um disartikulierte Platten von coccosteiden Arthrodiren und um Acanthodierreste. Die Coccosteiden müssen in eine neue Art und — falls eine Zusammengehörigkeit der Schädelreste mit den Rumpfpanzerplatten besteht — sogar in eine neue Gattung gestellt werden. Die Acanthodier sind durch mehrere Kieferknochen von Ischnacanthidae indet. und einenMachaeracanthus-Flossenstachel vertreten.
