TL;DR: It is shown that structures retrieved from between the prosomal‐opisthosomal juncture comprise polygonal tubes 30–40 μm in diameter, which are interpreted as sarcomeral sheaths of muscular tissue.
Abstract: A new eurypterid, Rhenopterus waterstoni sp. nov., is described from the Gogo Formation (Frasnian, Upper Devonian) of Western Australia. This species is distinguished from related forms by the tuberculation of the anteriormost tergite and crenulated posterior margins of the carapace and opisthosomal segments. It is the only eurypterid specimen known from the Gogo Formation, the most complete eurypterid from Australia, and also the youngest representative of Rhenopterus in the fossil record. Structures retrieved from between the prosomal-opisthosomal juncture comprise polygonal tubes 30–40 μm in diameter, which are interpreted as sarcomeral sheaths of muscular tissue. Rhenopterus is reviewed: R. latus Stormer, 1936 is synonymized with R. diensti Stormer, 1936 as it is here recognized as a female sexual dimorph; R. maccarthyi (Kjellesvig-Waering, 1934) is an orthocone nautiloid.

TL;DR: The eurypterid Rhenopterus sievertsi Størmer from the Lower Devonian of Germany is redescribed and is transferred to Adelophthalmus Jordan, in Jordan and von Meyer and thus is the oldest representative of this geographically and stratigraphically widespread genus.
Abstract: The eurypterid Rhenopterus sievertsi Stormer from the Lower Devonian of Germany is redescribed. Based on new morphological data, including the possession of prosomal limbs of Adelophthalmus-type and spatulae on the genital operculum, the species is transferred to Adelophthalmus Jordan, in Jordan and von Meyer and thus is the oldest representative of this geographically and stratigraphically widespread genus. Eurypterus? trapezoides Stormer is recognized as a junior synonym of A. sievertsi.

TL;DR: In this paper, fossil associations as well as morphological details of some arthropod remains are briefly described, including the scorpionlike postabdomen of the eurypterid Rhenopterus diensti and the type B genital appendage of a Parahughmilleria hefteri specimen.
Abstract: Summary: Fossil-Lagerstatten in Lower Devonian marine to nonmarine deltaic transitional facies from the ArdennoRhenish Massif are presented. Some fossil associations as well as morphological details of some arthropod remains are briefly described, including the scorpionlike postabdomen of the eurypterid Rhenopterus diensti and the type B genital appendage of a Parahughmilleria hefteri specimen. The latter is the first eurypterid from the Grand Duchy of Luxembourg. A centipede myriapod, the arthropod trackway Diplichnites gouldi, and the “fish” swimming trail Undichna isp. are for the first time recorded from the Lower Devonian of the Ardenno-Rhenish Massif and the possible producers of the trace fossils are discussed.
