Heteromorph ammonite Parapatoceras from the Lower Callovian of Villány, South Hungary

In the rich Middle Jurassic ammonite fauna of the famous ammonitic bank of Villány, South Hungary, recently a Parapatoceras specimen was found. This ammonite, a Callovian heteromorph, usually occurs in Callovian assemblages in Europe and elsewhere, however, the appearance in the Villány fauna, known on the basis of thousands of specimens and worked out in two classic monographs, seems to be a true rarity. The specimen is formally described, and previous records of Middle Jurassic heteromorph ammonites from Hungary are briefly summarized.
