Ostracodes from the Devonian-Carboniferous boundary beds in Thuringia (Germany)
83 species of ostracodes belonging to faunas of the Thuringian and of the Entomozoe Ökotype are known from the uppermost limestone layers of the Wocklumeria Stage and the lowermost layers of the Gattendorfia Stage in the Thuringian Slate Mountains (Schwarzburg Anticline). 35 species and 6 genera died out at the Devonian-Carboniferous boundary; only 18 range across the boundary and 44 new species appeared in the lower part of the Gattendorfia Stage. There is a break in ostracode assemblages at the Devonian-Carboniferous boundary, which is particularly noticeable among the highly specialised and short ranging taxa of the Thuringian Ökotype. The changes must be related to a super-regional global event.
