Abstract
The new larger benthic foraminifer Robustoconus tisljari n. gen., n. sp. is described from Middle Jurassic (Early Bajocian) high-energy shallow-water limestones of the Dubrovnik area in the south-eastern part of the Adriatic Carbonate Platform. Robustoconus represents a large dimorphic agglutinated foraminiferan with a coarse exoskeleton typical of representatives of the Family Hauraniidae. Differences to the allied genera Spiraloconulus ALLEMANN & SCHROEDER and Bostia BASSOULLET are discussed. The occurrence of a further new genus of larger foraminifera provides additional evidence for a high origination rate in the Middle Jurassic. The restriction of Robustoconus tisljari to the Timodonella sarda taxon-range zone highlights its biostratigraphic interest.
