Between 14 to 15 million year old fossilized Capros radobojanus I found in the sandstones of Sankt Margarethen (Burgenland/Austria). During this time period the tropical Paratethys covered the vast majority of the Vienna and Pannonian Basin. Repeated algea blooms in the shallow bay area of what is nowadays the Eisenstädter Basin led to mass fish dyings in this section of the ocean, resulting in the fossil rich layers you can find today.
