Balaenognathus Maeuseri
''Balaenognathus'' (meaning "bowhead whale jaw") is an extinct genus of ctenochasmatid pterosaurs from the Late Jurassic Torleite Formation of Bavaria, Germany. The genus contains a single species, ''B. maeuseri'', known from a nearly-complete, articulated skeleton. Discovery and naming The ''Balaenognathus'' holotype specimen, NKMB P2011-633, was discovered in sediments of the Torleite Formation, dated to the upper Kimmeridgian–Tithonian ages of the late Jurassic period, near Wattendorf, Bavaria, in southern Germany. The fossil was accidentally discovered in September 2011 while crocodylomorph bones were being collected. The specimen consists of a well-preserved, nearly-complete, Joint, articulated individual. Patagium#Pterosaurs, Wing membrane soft tissue is preserved in a small part of the specimen. The specimen is preserved on a Compression fossil, slab consisting of 17 pieces, lacking only part of the left wing-finger metacarpal, the articular area of a wing-finger Phala ...

Late Jurassic
The Late Jurassic is the third Epoch (geology), epoch of the Jurassic Period, and it spans the geologic time scale, geologic time from 161.5 ± 1.0 to 143.1 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic stratum, strata.Owen 1987. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age. In the past, ''Malm'' was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units. Subdivisions The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock: Paleogeography During the Late Jurassic Epoch, Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south. The result of this break-up was the emergence of the Atlantic Ocean, which initially was relatively narrow. Life forms This epoch is well known for many famous types of d ...
