- Title
The new early Palaeozoic rugose coral genera Eurogrewingkia gen. nov. and Fosselasma gen. nov.
- Authors
Neuman, Björn E. E.
- Abstract
The new genus Eurogrewingkia gen. nov. (type species selected here is Grewingkia bilateralis Neuman, 1969) is erected for streptelasmatid rugose corals with Grewingkia-like ontogeny lacking a cardinal fossula sensu stricto. In addition, the new genus Fosselasma gen. nov. (type species selected here is Streptelasma unicum Neuman, 1975) is erected for species with a Streptelasma-like ontogeny but provided with a cardinal septofossula. Species of Eurogrewingkia are currently recognized from the Upper Ordovician, Rawtheyan--Hirnantian strata in Europe and North America. Species of Fosselasma are found only in Hirnantian strata in Sweden and Norway.
