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 including wackestones , packstones and grainstones , as well as mudstone .[1] 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.[2] teleosaurid crocodyliformes are also known, including Sericodon , Proexochokefalos and Machimosaurus .[3] The metriorhynchid thalatosuchians Torvoneustes [4] and Dakosaurus . The hybodontid shark Asteracanthus .[5] The thalassochelydian turtle Thalassemys [6] and Solnhofia is known from the formation,[7] as is the platychelyid turtles Platychelys ,[8] and the plesiochelyid turtle Plesiochelys .[9]
