Reuchenette Formation
jurassic-era geologic formation in Switzerland
The Reuchenette Formation is a Jurassic geologic formation in Switzerland. It is Kimmeridgian in age,precisely dated through ammonites between 152.7 to 152 mya. It predominantly consists of well stratified limestone, with lithology variable both laterally and stratigraphically including wackestones, packstones and grainstones, as well as mudstone. Dinosaur remains are among the fossils that have been recovered from the formation, including the Turiasaurian sauropod Amanzia greppini, alongside a theropod tooth belonging to Ceratosauria indet, originally assigned to Megalosaurus meriani. teleosaurid crocodyliformes are also known, including Sericodon, Proexochokefalos and Machimosaurus. The metriorhynchid thalatosuchians Torvoneustes and Dakosaurus. The hybodontid shark Asteracanthus. The thalassochelydian turtle Thalassemys and Solnhofia is known from the formation, as is the platychelyid turtles Platychelys, and the plesiochelyid turtle Plesiochelys.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Reuchenette Formation”, the useful work is to connect “jurassic-era geologic formation in Switzerland” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 7, 2026. The linked authority identifier is Q7317542. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
