Ordovizische Seeigel aus Geschieben

Sclerites of three of the four species of Bothriocidaris known from outcrops in Estonia are found as microfossils in Ordovician erratic boulders, among them B. parvus which was known until now by one specimen only. Furthermore Neobothriocidaris is reported for the first time from the Baltic region by a species known until now only from Scotland (AP. minor).
