Neobeyrichia from the Silurian of Bjärsjölagård, Scania, Sweden
In Bjärsjölagård layer 1b the genus Neobeyrichia is represented by Neobeyrichia spinulosa (Boll) and Neobeyrichia regnans Martinsson. N. spinulosa dominates strongly. It is here redescribed and the appearence of the last moulting stage is described. N. spinulosa was a marine, benthic species. Previous reports of N. spinulosa from Gotland (Sweden) and Denny's Formation (eastern USA) are wrong.
