Archaeopteryx, sometimes referred to by its German name, "Urvogel" is a genus of bird-like dinosaurs. The name derives from the ancient Greek ἀρχαῖος (archaīos), meaning "ancient", and πτέρυξ (ptéryx), meaning "feather" or "wing". Between the late 19th century and the early 21st century, Archaeopteryx was generally accepted by palaeontologists and popular reference books as the oldest known bird. Older potential avialans have since been identified, including Anchiornis, Xiaotingia, and Aurornis.
The Solnhofen Limestone or Solnhofen Plattenkalk, formally known as the Altmühltal Formation, is a Jurassic Konservat-Lagerstätte that preserves a rare assemblage of fossilized organisms, including highly detailed imprints of soft bodied organisms such as sea jellies. The most familiar fossils of the Solnhofen Plattenkalk include the early feathered theropod dinosaur Archaeopteryx preserved in such detail that they are among the most famous and most beautiful fossils in the world. The Solnhofen beds lie in the German state of Bavaria (Bayern), halfway between Nuremberg (Nürnberg) and Munich (München) and were originally quarried as a source of lithographic limestone. The Jura Museum situated in Eichstätt, Germany has an extensive exhibit of Jurassic fossils from the quarries of Solnhofen and surroundings, including marine reptiles, pterosaurs, and one specimen of the early bird Archaeopteryx.
Compsognathus is a genus of small, bipedal, carnivorous theropod dinosaur. Members of its single species Compsognathus longipes could grow to around the size of a chicken. They lived about 150 million years ago, during the Tithonian age of the late Jurassic period, in what is now Europe. Paleontologists have found two well-preserved fossils, one in Germany in the 1850s and the second in France more than a century later. Today, C. longipes is the only recognized species, although the larger specimen discovered in France in the 1970s was once thought to belong to a separate species and named C. corallestris.
Juravenator is a genus of small coelurosaurian theropod dinosaur, which lived in the area which would someday become the top of the Franconian Jura of Germany, about 151 or 152 million years ago. It is known from a single, juvenile specimen.
Compsognathidae is a family of coelurosaurian theropod dinosaurs. Compsognathids were small carnivores, generally conservative in form, hailing from the Jurassic and Cretaceous Periods. The bird-like features of these species, along with other dinosaurs such as Archaeopteryx inspired the idea for the connection between dinosaur reptiles and modern-day avian species. Compsognathid fossils preserve diverse integument — skin impressions are known from four genera commonly placed in the group, Compsognathus, Sinosauropteryx, Sinocalliopteryx, and Juravenator. While the latter three show evidence of a covering of some of the earliest primitive feathers over much of the body, Juravenator and Compsognathus also show evidence of scales on the tail or hind legs. "Ubirajara jubatus", informally described in 2020, had elaborate integumentary structures on its back and shoulders superficially similar to the display feathers of a standardwing bird-of-paradise, and unlike any other non-avian dinosaur currently described.
Mörnsheim, or Moernsheim, is a municipality in the district of Eichstätt in Bavaria in Germany. It lies on the river Gailach and the surrounding rocks date back to the Late Jurassic (Tithonian).
The Solnhofen Limestone or Solnhofen Plattenkalk is a collective term for multiple Late Jurassic lithographic limestones in southeastern Germany, which is famous for its well preserved fossil flora and fauna dating to the late Jurassic (Kimmeridgian-Tithonian). The paleoenvironment is also often referred to as the Solnhofen Archipelago. The Solnhofen Archipelago was located at the northern edge of the Tethys Ocean as part of a shallow epicontinental sea and is firmly a part of the Mediterranean realm.
Non-avian dinosaur and bird fossils are frequently found in a characteristic posture consisting of head thrown back, tail extended, and mouth wide open. The cause of this posture—often called a "death pose"—has been a matter of scientific debate. Traditional explanations ranged from strong ligaments in the animal's neck desiccating and contracting to draw the body into the pose, to water currents arranging the remains in the position.
The Vega Formation is a Late Jurassic (Kimmeridgian) geologic formation of the Ribadesella Group in Asturias, Spain. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. The formation is around 150 metres thick and consists of "alternating white, pale grey and reddish sandstones, and red mudstones with several sporadic conglomeratic beds typically arranged in minor finnig-upward cycles within a major cycle of the same character". An isolated caudal theropod vertebra and a partial tooth are known from the formation, belonging to large megalosaurids around 10 metres in length, comparable to Torvosaurus. Other remains known from the formation include fragmentary turtle remains, crocodylomorph teeth, as well as a sauropod caudal vertebra (MUJA-0650). Dinosaur tracks are also known from the formation, including large theropod footprints and poorly preserved quadrupedal dinosaur footprints.
The Tereñes Formation or Tereñes Marl is a Late Jurassic (Kimmeridgian) geologic formation in Asturias, Spain. The grey marls of the formation were deposited in a lagoonal environment at a muddy coast along a temporary inland sea. The lower section of the formation comprises silty and chalky sandstones with desiccation cracks and ripple marks, then becomes a bituminous, prominently ostracod-bearing, pelecypod shell chalk, lime chalk marl and marl. Fossil tracks have been reported from the formation.
Archaeopteryx fossils from the quarries of Solnhofen limestone represent the most famous and well-known fossils from this area. They are highly significant to paleontology and avian evolution in that they document the fossil record's oldest-known birds.
Sciurumimus is an extinct genus of tetanuran theropod from the Late Jurassic Torleite Formation of Germany. It is known from a single juvenile specimen representing the type species, Sciurumimus albersdoerferi, which was found in a limestone quarry close to Painten in Lower Bavaria. The specimen was preserved with traces of feather-like filaments.
The Mörnsheim Formation is a geologic formation in Germany, near Daiting and Mörnsheim, Bavaria. It preserves fossils dating back to the Jurassic period. It overlies the older Altmühltal Formation in its northwestern extent, and the Painten Formation to the east.
The Torleite Formation is a geologic formation and Lagerstätte in Germany. It preserves fossils dating to the Kimmeridgian stage of the Jurassic period. Animals recovered from the formation include the small theropod dinosaur Sciurumimus, the ctenochasmatid pterosaur Balaenognathus, and the extinct bony fish Anaethalion.
Ostromia is a genus of anchiornithid theropod dinosaur from the Late Jurassic Painten Formation of Germany. The genus contains a single species, O. crassipes, named by Christian Foth and Oliver Rauhut in 2017.
Anchiornithidae is a family of small paravian dinosaurs. Anchiornithids have been classified at varying positions in the paravian tree, with some scientists classifying them as a distinct family, a basal subfamily of Troodontidae, members of Archaeopterygidae, or an assemblage of dinosaurs that are an evolutionary grade within Avialae or Paraves.
Alcmonavis is a basal genus of avialan dinosaur that during the Late Jurassic lived in the area of present Germany. The only named species in the genus is Alcmonavis poeschli. Its only known fossil was originally reported as a specimen of Archaeopteryx.
Balaenognathus 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.
Schoenesmahl is an extinct genus of lizard from the Late Jurassic Painten Formation of Germany. It contains only a single species, S. dyspepsia.
