Species of Nannirhynchia Buckman, 1918 are particularly abundant in the stratigraphic record of Early Jurassic age outcropping in the Lusitanian Basin, where they represent important biostratigraphic tools, especially where ammonites are missing or are not well preserved. An attempt of a correlation scheme of ammonite and brachiopod zones from the Mediterranean and the northern European provinc...

New fossil collections from two Callovian (Middle Jurassic) localities of the South Hungarian Villány Hills (Villány, Templom Hill Quarry and Siklós, Rózsa Quarry) include specimens rare ammonite genus Phlycticeras sporadic Oecoptychius. A review is given herein on previously published newly found specimens. Dimorphism, as well palaeogeographical distribution genera, also briefly discussed.

A new genus and species of pycnodontiform fishes, Grimmenodon aureum, from marginal marine, marine-brackish lower Toarcian (Harpoceras exaratum ammonite subzone) clay deposits of Grimmen in northeastern Germany is described.
