Pleuropholidae is an extinct family of stem-teleost fish that lived from the Middle Jurassic to the Early Cretaceous. It is one of several families that were historically placed in the paraphyletic order Pholidophoriformes. [1] [2] Pleuropholids can be distinguished from other "pholidophoriforms" by the elongated scales on the sides of their bodies. [1]
The Jurassic is a geologic period and stratigraphic system that spanned from the end of the Triassic Period 201.4 million years ago (Mya) to the beginning of the Cretaceous Period, approximately 145 Mya. The Jurassic constitutes the middle period of the Mesozoic Era as well as the eighth period of the Phanerozoic Eon and is named after the Jura Mountains, where limestone strata from the period were first identified.
The insect order Neuroptera, or net-winged insects, includes the lacewings, mantidflies, antlions, and their relatives. The order consists of some 6,000 species. Neuroptera is grouped together with the Megaloptera and Raphidioptera (snakeflies) in the unranked taxon Neuropterida.
Ichthyodectiformes is an extinct order of marine stem-teleost ray-finned fish. The order is named after the genus Ichthyodectes, established by Edward Drinker Cope in 1870. Ichthyodectiforms are usually considered to be some of the closest relatives of the teleost crown group.
Pleuropholis is an extinct genus of prehistoric ray-finned fish.
The Speeton Clay Formation (SpC) is a Lower Cretaceous geological formation in Yorkshire, northern England. Unlike the contemporaneous terrestrial Wealden Group to the south, the Speeton Clay was deposited in marine conditions. The most common fossils in the unit are belemnites, followed by ammonites and the lobster Meyeria ornata. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
Crossognathiformes is an extinct order of ray-finned fish that lived from the Late Jurassic to the Eocene. Its phylogenetic placement is disputed; some authors have recovered it as part of the teleost stem group, while others place it in a basal position within crown group Teleostei. Other placements have found it to be paraphyletic, with the Varasichthyidae being stem-group teleosts whereas the other, "true" crossognathiforms are crown-group teleosts within the Teleocephala.
