Painten Formation
The Painten Formation is a geologic formation in Germany. It preserves fossils dating back to the Tithonian stage of the Late Jurassic period.Painten Formation at .org Description It is roughly contemporary with the Altmühltal Formation (which includes the true Solnhofen limestone), as they both underlay the |
Formation (stratigraphy)
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob We ...

Ostromia
''Ostromia'' (''Thick feet of John Ostrom'') 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. Discovery and naming The holotype was discovered near Riedenburg, Germany in 1855 and it was originally misidentified as a species of a pterodactyloid pterosaur and named ''Pterodactylus crassipes'' in 1857. In 1970 it was identified as an ''Archaeopteryx'' by paleontologist John Ostrom, who called it the "Haarlem specimen", since it was kept in the Teylers Museum in Haarlem.Ostrom JH. Archaeopteryx: notice of a “new” specimen. Science. 1970;170:537–8 In 2017 Christian Foth and Oliver Rauhut concluded it was more closely related to the Chinese ''Anchiornis'' and introduced the generic name ''Ostromia'', named after Ostrom. The only known specimen is fairly incomplete compared to most specimens of ''Archaeopteryx'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scheenstia
''Scheenstia'' is an extinct genus of neopterygian ray-finned fish from the Late Jurassic–Early Cretaceous of Europe. Fossils have been found in both marine and freshwater environments. Most species of the genus were previously referred to the related genus ''Lepidotes'', but all Late Jurassic–Early Cretaceous species of that genus have since been re-classified as ''Scheenstia'' following detailed phylogenetic analysis. It is a member of Lepisosteiformes meaning that is closest living relates are gars. The teeth of ''Scheenstia'' are low and rounded, and were likely used for crushing hard shelled organisms (durophagy). One species, the marine ''Scheenstia maximus'' from the Late Jurassic of Germany, could reach body lengths in excess of 1.5 metres. Classification ''Scheenstia'' is related to the genus ''Lepidotes''. The latter has been one of the greatest actinopterygian wastebasket taxa, with one 2012 study finding species referrable to a minimum of three different and dista ...

Paracestracion
''Paracestracion'' is an extinct genus of heterodontid sharks from Early Jurassic to Early Cretaceous-aged rocks of England, France, Germany and Luxembourg. The genus, first described in 1911 by Ernst Hermann Friedrich von Koken in Karl Alfred von Zittel, Zittel, K. A., (1911): ''Grundzüge der Paläontologie (Paläozoologie).'' Neubearbeitet von F. Broili, E. Koken, M. Schlosser. II. Abteilung. Vertebrata. Oldenbourg 1911. Zweite vermehrte und verbesserte Auflage. Gr.8°. VII, 598 S. contains five species: ''P. bellis'' from the Bathonian of England, the type species ''P. falcifer'' from the Tithonian and Kimmeridgian of Weymouth, England and Solnhofen, Germany, which was originally named as a species of ''Cestracion'' (now seen as a synonym of '' Heterodontus'') in 1857 by Johann Andreas Wagner, Wagner, J.

Pterodactyloidea
Pterodactyloidea (derived from the Greek words ''πτερόν'' (''pterón'', for usual ''ptéryx'') "wing", and ''δάκτυλος'' (''dáktylos'') "finger" meaning "winged finger", "wing-finger" or "finger-wing") is one of the two traditional suborders of pterosaurs ("wing lizards"), and contains the most derived members of this group of flying reptiles. They appeared during the middle Jurassic Period, and differ from the basal (though paraphyletic) rhamphorhynchoids by their short tails and long wing metacarpals (hand bones). The most advanced forms also lack teeth, and by the late Cretaceous, all known pterodactyloids were toothless. Many species had well-developed crests on the skull, a form of display taken to extremes in giant-crested forms like '' Nyctosaurus'' and '' Tupandactylus''. Pterodactyloids were the last surviving pterosaurs when the order became extinct at the end of the Cretaceous Period, together with the non-avian dinosaurs and most marine reptiles. " Pter ...

Ichthyosauria
Ichthyosaurs (Ancient Greek for "fish lizard" – and ) are large extinct marine reptiles. Ichthyosaurs belong to the order known as Ichthyosauria or Ichthyopterygia ('fish flippers' – a designation introduced by Sir Richard Owen in 1842, although the term is now used more for the parent clade of the Ichthyosauria). Ichthyosaurs thrived during much of the Mesozoic era; based on fossil evidence, they first appeared around 250 million years ago ( Ma) and at least one species survived until about 90 million years ago, into the Late Cretaceous. During the Early Triassic epoch, ichthyosaurs and other ichthyosauromorphs evolved from a group of unidentified land reptiles that returned to the sea, in a development similar to how the mammalian land-dwelling ancestors of modern-day dolphins and whales returned to the sea millions of years later, which they gradually came to resemble in a case of convergent evolution. Ichthyosaurs were particularly abundant in the Late Triassic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhamphorhynchus
''Rhamphorhynchus'' (, from Ancient Greek ''rhamphos'' meaning "beak" and ''rhynchus'' meaning "snout") is a genus of long-tailed pterosaurs in the Jurassic period. Less specialized than contemporary, short-tailed pterodactyloid pterosaurs such as ''Pterodactylus'', it had a long tail, stiffened with ligaments, which ended in a characteristic soft-tissue tail vane. The mouth of ''Rhamphorhynchus'' housed needle-like teeth, which were angled forward, with a curved, sharp, beak-like tip lacking teeth, indicating a diet mainly of fish; indeed, fish and cephalopod remains are frequently found in ''Rhamphorhynchus'' abdominal contents, as well as in their coprolites. Although fragmentary fossil remains possibly belonging to ''Rhamphorhynchus'' have been found in England, Tanzania, and Spain, the best preserved specimens come from the Solnhofen limestone of Bavaria, Germany. Many of these fossils preserve not only the bones but impressions of soft tissues, such as wing membranes. Scat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solnhofia
''Solnhofia'' is a genus of extinct thalassochelydian turtle from the Late Jurassic of Germany. The type species is ''Solnhofia parsonsi'', named by Gaffney in 1975 for a partial skull and jaw from the early Tithonian of the Solnhofen Formation in Bavaria. Additional material including a complete skeleton is known from the late Kimmeridgian of Switzerland and the Kimmeridgian/Tithonian of other deposits within Bavaria, and potentially also unprepared material from the Late Jurassic of France. The genus was referred to the family Eurysternidae by Anquetin and colleagues in 2017, which may represent an artificial grade of early thalassochelydians. In 2020 a new species ''Solnhofia brachyrhyncha'' was described from the Kimmeridigan aged Reuchenette Formation The Reuchenette Formation is a Jurassic geologic formation in Switzerland. It is Kimmeridgian in age and predominantly consists of well stratified limestone, with lithology variable both laterally and stratigraphically in ...
