The SHRIMP ion microprobe has been used to date zircons in a 1 cm thick bentonite located in the Hasselbachtal auxiliary global stratotype section through the Devonian-Carboniferous boundary in Germany, and a tuff located at a similar biostratigraphic level in Australia. Multiple replicate analyses have yielded indistinguishable ages, and indicate 353.2±4.0 Ma (2σ) as the age of the boundary. Obtaining an age for the boundary in the German reference section depended on the ability of SHRIMP to date a small sample and to target small areas of structurally complex zircons. Future refinements of the age of this boundary may depend on re-analysis of this uniquely placed bentonite, and this highlights the value of defining biostratigraphic stratotypes in the vicinity of known dateable horizons.

“…This peculiarity was already recognised and discussed by Vöhringer (1960: 188). His assumption that the "Stockum Fauna" is stratigraphically a little older than the assemblages from Oberrödinghausen was later confirmed by the examination of the conodonts (Ziegler 1969;Alberti et al 1974;Clausen et al 1994). The Stockum assemblage has not been recorded at Oberrödinghausen; the lowest part of the basal bed 6 at Oberrödinghausen already yielded specimens of Gattendorfia.…”

The railway cutting near Oberrödinghausen at the northern margin of the Rhenish Mountains is the cardinal section for the investigation of Early Tournaisian (Early Carboniferous; Mississippian) ammonoids. The ammonoids from the Hangenberg Limestone (= Gattendorfia Limestone) of this and neighbouring outcrops are revised here, using the historical collections as well as undescribed new material. The ammonoid assemblages are composed of a total of 67 species, which occur in four successive ammonoid zones. The assemblages are composed of predominant prionoceratids (Order Goniatitina) with the twenty genera Mimimitoceras (two species), Globimitoceras (one species), Paragattendorfia (two species), Kornia (three species), Stockumites (eleven species), Acutimitoceras (two species), Costimitoceras (one species), Nicimitoceras (four species), Imitoceras (one species), Voehringerites (one species), Gattendorfia (eight species), Zadelsdorfia (two species), Kazakhstania (one species), Gattenpleura (one species), Weyerella (three species), Hasselbachia (three species), Paprothites (five species), Pseudarietites (three species), Rodingites (two species), Paralytoceras (one species) as well as subordinate eocanitids (Order Prolecanitida) with the genera Eocanites (eight species) and Nomismocanites (one species). The new genera Rodingites gen. nov. and Nomismocanites gen. nov. as well as the new species Mimimitoceras perditum sp. nov., Kornia fibula sp. nov., Kornia acia sp. nov., Stockumites parallelus sp. nov., Stockumites voehringeri sp. nov., Acutimitoceras ucatum sp. nov., Acutimitoceras paracutum sp. nov., Imitoceras initium sp. nov., Gattendorfia rhenana sp. nov., Gattendorfia bella sp. nov., Gattendorfia valdevoluta sp. nov., Gattendorfia schmidti sp. nov., Gattendorfia corpulenta sp. nov., Gattendorfia immodica sp. nov., Zadelsdorfia oblita sp. nov., Weyerella lenis sp. nov., Hasselbachia erronea sp. nov., Paprothites beckeri sp. nov., Paprothites kullmanni sp. nov., Eocanites delicatus sp. nov. and Nomismocanites raritas gen. et sp. nov. are described from Oberrödinghausen. Mimimitoceras mina sp. nov., Stockumites marocensis sp. nov., Zadelsdorfia zana sp. nov. and Kazakhstania kana sp. nov. are newly named for material from the Anti-Atlas of Morocco.

“…This includes representatives of the genera A thin (7.62 cm) rottenstone, developed between 6.40 m and 6.47 m, yields .he proetid Drevermannia moravica minuta described from the Gattendorfia Stufe (Osmolska,962). This species is followed immediately by Archegonus {Phillibole) drewerensis, the earliest record of which is from the Stockum Limestone (Alberti et al 1974), associated with specifically unidentifiable protognathodids. Beneath this horizon, greyish green micaceous slates crowded with trilobite fragments and posidoniid bivalves persist to 10.41 m. The entomozoid Maternella clathrata first appears at 6.45 m and is associated after 6.54 m with Siphonodella sulcata, Pseudopolygnathus primus, Po.…”

“…Bioturbation is not marked and the impoverished benthos in the beds indicate an environment somewhat hostile to benthic life, but by no means truly basinal. The thickness of the Gattendorfia Stufe at Chillaton (5.4 m) is intermediate in thickness between the condensed Gattendorfia Limestone of the Honne Valley (1.5 m Paproth, 1971) and the 40 m of silty slates described from Stockum (Alberti et al 1974). No close comparison can be made with the shelf limestone developments of the Lower Carboniferous where siphonodellid conodonts appear to be rare (Rhodes, Austin & Druce, 1969), for these forms dominate the Chillaton fauna.…”

SummaryBoreholes penetrating the inverted limb of a major fold in an allochthonous thrust sheet at Chillaton, West Devon, revealed highly fossiliferous strata spanning the Devonian–Carboniferous boundary in continuous succession. Details of the fauna, which includes conodonts, trilobites and ostracods, are given. Abundant siphonodellid conodonts allow the boundary to be determined according to the recommendations of the working group on the Devonian–Carboniferous boundary of the IUGS Commission on Stratigraphy. The nature of the imbricate zone beneath the Main Thrust, in which the succession is situated, is described. In addition, the fabrics associated with thrusts which cut the olistostromic succession lower in the tectonic unit are discussed.
