Temporal range: Jurassic
The Kimmeridge Clay is a sedimentary deposit of fossiliferous marine clay which is of Late Jurassic to lowermost Cretaceous age and occurs in southern and eastern England and in the North Sea. This rock formation is the major source rock for North Sea oil. The fossil fauna of the Kimmeridge Clay includes turtles, crocodiles, sauropods, plesiosaurs, pliosaurs and ichthyosaurs, as well as a number of invertebrate species.Leptolepidae
Leptolepidae ("Delicate Scales") is an extinct family of herring-like Mesozoic teleosts found throughout the world. They were among the first teleosts to have fully ossified vertebrae.List of prehistoric bony fish genera
This List of prehistoric bony fish is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be bony fish (class osteichthyes), excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (nomina dubia), or were not formally published (nomina nuda), as well as junior synonyms of more established names, and genera that are no longer considered members of osteichthyes.
This list includes 1,386 generic names.
Extinct genera are marked with a dagger (†).
Extant genera are bolded.Osteoglossomorpha
The Osteoglossomorpha are a group of bony fish in the Teleostei.Paleobiota of the Solnhofen Formation
The Solnhofen Plattenkalk, or Solnhofen Limestone Formation, is famous for its well preserved fossil flora and fauna.Wessex Formation
The Wessex Formation is a fossil-rich English geological formation that dates from the Berriasian to Barremian stages (about 145–125 million years ago) of the Early Cretaceous. It forms part of the Wealden Group and underlies the younger Vectis Formation and overlies the Durlston Formation. The dominant lithology of this unit is mudstone with some interbedded sandstones.
