Klettgau Formation (Switzerland)

The Klettgau Formation is a geological formation in Switzerland. It is Late Triassic in age, covering most of the mid to late Norian, the Carnian, and into the Rhaetian, spanning a period of 26-30 million years. [1]

Description

The primary depositional environment was that of a playa with marine and fluvial intercalations. The lithology is quite variable consisting primarily of fine grained rocks typically claystones and dolocretes, often with sandstone or carbonatic fluvial channel fills. [2]

Fossil content

Dinosaur fossils are known from the formation, including those of Plateosaurus, Notatesseraeraptor frickensis and Schleitheimia [3] [4]

The following other fossils were found in the formation: [1]

Prozostrodontia
Reptiles
Amphibians
Fish
Invertebrates

<i>Melanorosaurus</i> Sauropodomorph dinosaur genus from the Late Triassic period

Melanorosaurus is a genus of basal sauropodomorph dinosaur that lived during the Late Triassic period. An omnivore from South Africa, it had a large body and sturdy limbs, suggesting it moved quadrupedally. Its limb bones were massive and heavy like the limb bones of true sauropods.

<i>Procompsognathus</i> Extinct genus of dinosaurs

Procompsognathus is an extinct genus of coelophysid theropod dinosaur that lived approximately 210 million years ago during the later part of the Triassic Period, in what is now Germany. Procompsognathus was a small-sized, lightly built, ground-dwelling, bipedal carnivore, that could grow up to 1 m (3.3 ft) long.

<i>Isanosaurus</i> Genus of dinosaurs

Isanosaurus is an extinct genus of sauropod dinosaur from Thailand. It was originally dated to approximately 210 million years ago during the Late Triassic, which would make it one of the oldest known sauropods. Its age was later considered uncertain, and may be Early Jurassic or even as young as Late Jurassic. The only species is Isanosaurus attavipachi. Though important for the understanding of sauropod origin and early evolution, Isanosaurus is poorly known. Exact relationships to other early sauropods remain unresolved.

<i>Lessemsaurus</i> Sauropodomorph dinosaur genus from Late Triassic Argentina

Lessemsaurus is an extinct genus of sauropodiform dinosaur belonging to Lessemsauridae.

<i>Liliensternus</i> Extinct genus of dinosaurs

Liliensternus is an extinct genus of basal neotheropod dinosaur that lived approximately 210 million years ago during the latter part of the Triassic Period in what is now Germany. Liliensternus was a moderate-sized, bipedal, ground-dwelling carnivore, that could grow up to 5.15 m (16.9 ft) long. It is the best represented Triassic theropod from Europe and one of the largest known.

<i>Gresslyosaurus</i> Prosauropod dinosaur

Gresslyosaurus is a genus of plateosaurian sauropodomorph dinosaur that lived during the Late Triassic period, around 214 to 204 million years ago, in France, Germany, Norway, Greenland and Switzerland.

Zanclodon is an extinct genus of archosauriform from the Erfurt Formation in southern Germany. It was once a wastebasket taxon until a taxonomic revision by Schoch (2011) left only the paratype within Zanclodon laevis proper. The type species is Z. laevis.

<span class="mw-page-title-main">Plateosauridae</span> Extinct family of dinosaurs

Plateosauridae is a family of plateosaurian sauropodomorphs from the Late Triassic of Europe, Greenland, Africa and Asia. Although several dinosaurs have been classified as plateosaurids over the years, the family Plateosauridae is now restricted to Plateosaurus, Yimenosaurus, Euskelosaurus, and Issi. In another study, Yates (2003) sunk Sellosaurus into Plateosaurus. Gresslyosaurus is alternatively considered its own genus or a synonym of Plateosaurus.

<span class="mw-page-title-main">Massopoda</span> Extinct clade of dinosaurs

Massopoda is a clade of sauropodomorph dinosaurs which lived during the Late Triassic to Late Cretaceous epochs. It was named by paleontologist Adam M. Yates of the University of the Witwatersrand in 2007. Massopoda is a stem-based taxon, defined as all animals more closely related to Saltasaurus loricatus than to Plateosaurus engelhardti.

The Exter Formation is the only formation of the Upper Keuper or Rhätsandstein, and is a geologic formation in Germany. It preserves fossils dating back to the Rhaetian of the Triassic period.

Sefapanosaurus was an early, herbivorous sauropodomorph dinosaur occurring in the southern regions of Gondwana some 200 million years ago in the Late Triassic or Early Jurassic. The sauropodomorphs were the dominant terrestrial herbivores throughout much of the Mesozoic Era, from their origins in the mid-Triassic until their decline and fall at the end of the Cretaceous. A distinctive feature of this dinosaur is the cross-shaped astragalus or talus bone in its ankle. The generic name is derived from the Sesotho word sefapano, meaning ‘cross’ and the Greek word saurus, meaning 'lizard'. The specific name refers to Zastron, the type locality, where the specimen was discovered.

<i>Notatesseraeraptor</i> Genus of reptiles (fossil)

Notatesseraeraptor is a genus of carnivorous theropod dinosaur that lived during the Late Triassic of what is now Switzerland. It was found in the Gruhalde Member of the Klettgau Formation. It was an early member of Neotheropoda with affinities to Dilophosaurus and Averostra. The new genus and species Notatesseraeraptor frickensis was named by Marion Zahner and colleagues in 2019.

Schleitheimia, is an extinct genus of sauropodiform sauropodomorph dinosaur, from the Gruhalde Member of Klettgau Formation of Switzerland. The type species, Schleitheimia schutzi was formally described in 2020.

Bernhard Peyer was a Swiss paleontologist and anatomist who served as a professor at the University of Zurich. A major contribution was on the evolution of vertebrate teeth.

Deltadectes is an extinct genus of early rhynchocephalian from the Late Triassic Klettgau Formation of Switzerland. It contains a single species, Deltadectes elvetica.
