Abstract
In the Komeuburg Basin echinoid remains are very rare; the specimens considered in this paper only come from the localities "Teiritzberg" and "Kamabrunn". The material consists of a single, fragmented corona, a cast of a spatangoid fragment, both of which could be only associated with the suborder Hemiasterina and a single spine, which possibly belongs to a spatangoid. These forms are deposit feeding endobionts, which are well adapted to clayey to sandy sediments and low water energy. In the Kreuzstetten Bay, however, echinoids are rather common; the material considered in this paper comes from temporary outcrops between Niederkreuzstetten and Neubau. In contrast to the Korneuburg Basin, in the Kreuzstetten Bay shallow burrowing sanddollars, namely Parascutella paulensis (AGASSIZ, 1841) and- less common - Amphiope, which are well adapted to sandy, high energy environments, are found.
