Hans-Volker K., Groening E., Brauckmann C., Schwarz D., Knoetschkje N. (2006) The Late Jurassic crocodiles of the Langenberg near Oker, Lower Saxony (Germany), and description of related materials (with remarks on the history of quarrying the “Langenberg Limestone” and “Obernkirchen Sandstone”) // Clausthaler Geowissenschaften. Bd.5. S.59-77.
The present article mainly deals with the description of remains of different species of crocodiles from the Late Jurassic (Kimmeridgian) of Oker (close to the northern slope of the Harz Mountains in Lower Saxony/Germany). These include the following species: Theriosuchus pusillus OWEN, 1878, Goniopholis simus OWEN, 1878, Machimosaurus hugii (H. V. MEYER, 1837), Steneosaurus aff. brevirostris OWEN, 1842, gen. et sp. indet. 1, and gen. et sp. indet. 2. Additionally, closely related crocodilian species from the late Jurassic as well as from the early Cretaceous (Berriasian, Bückeberg Member, “German Wealden”) in other regions of Lower Saxony are discussed. Phylogenetically, the crocodile fauna from Oker consists of different basal neosuchians crocodylomorphs.
