The Gosau Group is a geological stratigraphic group in Austria, Germany and western Slovakia whose strata date back to the Late Cretaceous to Eocene. It is exposed in numerous sporadic isolated basins within the Northern Calcareous Alps. It is divided into two subgroups, the Lower Gosau Subgroup which dates from the Turonian to Campanian, approximately 90 to 75 Ma and the Upper Gosau Subgroup which dates to the Santonian to Eocene, about 83.5 to 50 Ma. The formations within each subunit vary significantly between basins. The sequence is largely marine, but the Grünbach Formation represents a terrestrial deposit. Many of the units of the group are fossiliferous, typically providing marine fossils such as ammonites, though terrestrial remains including those of dinosaurs are known from the Grünbach Formation and Schönleiten Formation.
The Hensel Formation or Hensel Sand is a Mesozoic geologic formation in Texas. Fossil ornithopod tracks have been reported from the formation.
The Schrattenkalk Formation is a Barremian to Aptian geologic formation in the Alps. The limestone is highly karstified. Fossil ornithopod tracks have been reported from the formation. Iguanodont tracks have been registered in the Swiss portion of the formation. The famous north face of the Eiger is partly composed of Schrattenkalk, as well as the Sturmannshöhle in southernmost Bavaria, Germany, and the Hölloch and Silberen system karst caves in Switzerland.
Pygope is an extinct genus of brachiopods belonging to the family Pygopidae. These brachiopods lived in open sea from the Jurassic Period, Kimmeridgian age up to Cretaceous Period, Barremian age. Some of the species are characterised by a smaller or larger perforation through the entire shell in older specimens, while others just have a depression somewhere on the midline. Younger specimens of the perforated species develop a heart-shape and subsequently both extensions merge, thus encircling a central passage which is in fact entirely outside the shell.
The Del Rio Clay is a geologic formation in Texas. It preserves fossils dating back to the Cretaceous period.
The Hammett Shale is a geologic formation in Texas. It preserves fossils dating back to the Cretaceous period.
The Ferron Sandstone Member of the Mancos Shale is a geologic unit in Utah. It preserves fossils dating back to the Cretaceous period; and more specifically the middle Turonian.
The Georgetown Formation is a geologic formation in Mexico and the United States. It preserves fossils dating back to the Cretaceous period.
The Söhlde Formation is a geologic formation located in the federal states of Lower Saxony and Saxony-Anhalt in Germany. It preserves fossils from the Upper Cenomanian–lower Upper Turonian period.
The Strubberg Formation is a geologic formation in Germany. It preserves fossils dating back to the Jurassic period.
The Wetterstein Formation is a regional geologic formation of the Northern Limestone Alps and Western Carpathians extending from southern Bavaria, Germany in the west, through northern Austria to northern Hungary and western Slovakia in the east. The formation dates back to the Ladinian to Carnian stages of the Late Triassic. The formation is named after the Wetterstein Mountains in southern Germany and northwestern Austria. The center of its distribution, however, is in the Karwendel Mountains. It occurs in the Northern and Southern Limestone Alps and in the Western Carpathians.
The Kössen Formation is a Late Triassic (Rhaetian-age) geological formation in the Northern Calcareous Alps of Austria and Germany, in the Tiroler-Lech Nature Park. During the Late Triassic, the area now occupied by the Northern Calcareous Alps was instead a long, passive coastline at the western tip of the Neotethys Ocean. The environment was initially dominated by a wide and shallow carbonate platform within a lagoon between the shore and a string of reefs. This carbonate platform is nowadays preserved as the Carnian to Norian-age Hauptdolomit and Dachstein Formation. The Kössen Formation represents a period of increased siliciclastic clay input into the lagoon, covering up the carbonate platform with marls and marly limestones instead of pure limestone or dolomite. The Eiberg Member of the Kössen Formation was deposited in the Eiberg basin, a narrow strip of deeper water which developed between the carbonate platform and the shoreline in the later part of the Rhaetian.
The Garschella Formation is an early Aptian to early Cenomanian geologic formation in the Alps of Austria, France, Germany and Switzerland. It preserves fossils dated to the Cretaceous period.
The Trogkofel Formation is a geologic formation in Austria, Slovenia and Italy. It preserves fossils dating back to the Sakmarian to Artinskian stages of the Permian period.
The Steinalm Formation is a geologic formation in the Northern Limestone Alps, in Austria.
The Raibl Formation is an Upper Triassic geologic formation in the Northern and Southern Limestone mountain ranges of the Eastern Alps, in Central Europe.
The Oberrhaet Formation, also known as the Oberrhaet Limestone, is a Late Triassic (Rhaetian-age) geological formation in Austria. It is a unit of massive dark grey bioclastic limestones, found within the Northern Calcareous Alps. The Oberrhaet Limestone was originally a series of reefs which developed on the northwest edge of the Eiberg Basin, a narrow marine waterway extending along the northwestern tip of the Neotethys Ocean. The center of the Eiberg Basin is nowadays preserved as the Eiberg Member of the Kössen Formation, which was deposited southeast of the Oberrhaet Limestone and interfingers with it in many areas. The Oberrhaet Limestone was very similar to the Dachstein Limestone, which represented carbonate platforms and reefs on the southeast edge of the Eiberg Basin. The most prominent components of the reefs were giant frond-like colonies of Retiophyllia, a scleractinian coral.
Leyvachelys is an extinct genus of turtles in the family Sandownidae from the Early Cretaceous of the present-day Altiplano Cundiboyacense, Eastern Ranges, Colombian Andes. The genus is known only from its type species, Leyvachelys cipadi, described in 2015 by Colombian paleontologist Edwin Cadena. Fossils of Leyvachelys have been found in the fossiliferous Paja Formation, close to Villa de Leyva, Boyacá, after which the genus is named. The holotype specimen is the oldest and most complete sandownid turtle found to date.
