Lithacoceras is an extinct Ammonite cephalopod genus included in the superfamily Perisphinctoidea. These fast-moving nektonic carnivores lived during the Jurassic period, from the Oxfordian age to the Tithonian age. [1]
Fossils of species within this genus have been found in the Jurassic sediments of Antarctica, Argentina, Canada, Cuba, France, Germany, Madagascar, Somalia, Spain, United States and Yemen. [2]
Metriacanthosaurus is a genus of metriacanthosaurid dinosaur from the upper Oxford Clay of England, dating to the Late Jurassic period, about 160 million years ago.
Archaeidae, also known as assassin spiders and pelican spiders, is a spider family with about ninety described species in five genera. It contains small spiders, ranging from 2 to 8 millimetres long, that prey exclusively on other spiders. They are unusual in that they have "necks", ranging from long and slender to short and fat. The name "pelican spider" refers to these elongated jaws and necks used to catch their prey. Living species of Archaeidae occur in South Africa, Madagascar and Australia, with the sister family Mecysmaucheniidae occurring in southern South America and New Zealand.
Cacibupteryx is a genus of rhamphorhynchid pterosaur from the middle-late Oxfordian-age Upper Jurassic Jagua Formation of Pinar del Río, Cuba.
Nesodactylus was a genus of rhamphorhynchid pterosaur from the middle-late Oxfordian age Upper Jurassic Jagua Formation of Pinar del Río, western Cuba.
Aspidoceras is an extinct ammonoid cephalopod genus belonging to the family Aspidoceratidae.
Nemestrinidae, or tangle-veined flies is a family of flies in the superfamily Nemestrinoidea, closely related to Acroceridae. The family is small but distributed worldwide, with about 300 species in 34 genera. Larvae are endoparasitoids of either grasshoppers (Trichopsideinae) or scarab beetles (Hirmoneurinae). Some are considered important in the control of grasshopper populations. Adults are often observed on flowers.
The Berothidae are a family of winged insects of the order Neuroptera. They are known commonly as the beaded lacewings. The family was first named by Anton Handlirsch in 1906.
Steneosaurus is a dubious genus of teleosaurid crocodyliform from the Middle or Late Jurassic of France. The genus has been used as a wastebasket taxon for thalattosuchian fossils for over two centuries, and almost all known historical species of teleosauroid have been included within it at one point. The genus has remained a wastebasket, with numerous species still included under the label ‘Steneosaurus’, many of which are unrelated to each other.
Vinialesaurus is a genus of plesiosaur from the Late Jurassic (Oxfordian) Jagua Formation of Pinar del Río, Cuba. The type species is Vinialesaurus caroli, first described as Cryptocleidus caroli by De la Torre and Rojas in 1949, and redescribed by Gasparini, Bardet and Iturralde in 2002. The authors of the 2002 paper considered Vinialesaurus distinct enough from Cryptocleidus to warrant its own genus, but it was broadly similar to Cryptocleidus.
Bobbichthys is an extinct genus of ray-finned fish that lived in what is now Chile during the Oxfordian stage of the Late Jurassic epoch.
Varasichthys is an extinct genus of prehistoric bony fish that lived during the Oxfordian stage of the Late Jurassic epoch. Fossils have been found in the Domeyko Range of Antofagasta Region, northern Chile. The genus has been compared with other South American fishes as Luisiella and Protoclupea.
Chongichthys is an extinct genus of prehistoric bony fish that lived during the Oxfordian stage of the Late Jurassic epoch. Fossils of the genus have been found in the Quebrada El Profeta of Chile.
Protoclupea is an extinct genus of prehistoric bony fish that lived from the Oxfordian to the early Tithonian stage of the Late Jurassic epoch. Fossils have been found in the Domeyko Range of Antofagasta Region, northern Chile. The genus has been compared with other South American fishes as Luisiella and Varasichthys.
Eugnathides is an extinct genus of prehistoric bony fish that lived from the Oxfordian to the early Tithonian stage of the Late Jurassic epoch.
Ithonidae, commonly called moth lacewings and giant lacewings, is a small family of winged insects of the insect order Neuroptera. The family contains a total of ten living genera, and twelve extinct genera described from fossils. The modern Ithonids have a notably disjunct distribution, while the extinct genera had a more global range. The family is considered one of the most primitive living neuropteran families. Ithonids may be phytophagous. The family has been expanded twice, first to include the genus Rapisma, formerly placed in the monotypic family Rapismatidae, and then in 2010 to include the genera that had been placed into the family Polystoechotidae. Both Rapismatidae and Polystoechotidae have been shown to nest into Ithonidae sensu lato.
Hecticoceras is an ammonite genus belonging to the haploceratoid family Oppeliidae, that lived during the Middle and Late Jurassic, from the Callovian. Hecticoceras may be seen as a series of some nine subgenera, beginning with the lower Callovian H. (Hecticoceras) and H. (Hecticoceratoides) and ending with the lower Oxfordian H. (Pseudobrightia) and H. (Eochetoceras). Hecticocerassensu lato and Prohecticoceras from the underlying Bathonian form the oppeliid subfamily, Hecticoceratinae.
Cardioceras is an extinct ammonite genus belonging to the family Cardioceratidae. These fast-moving nektonic carnivores lived during the Jurassic period, Oxfordian age.
Ochetoceras is a genus of ammonites, belonging to the Oppeliidae, that lived during the Late Jurassic from the early Oxfordian to the early Tithonian, and type for the subfamily Ochetoceratinae.
Maiopatagium is an extinct genus of euharamiyids which existed in Asia during the Jurassic period. The type species is Maiopatagium furculiferum, which was described from the Tiaojishan Formation by Zhe-Xi Luo in 2017; it lived in what is now the Liaoning region of China during the late Jurassic. It possessed a patagium between its limbs and presumably had similar lifestyle to living flying squirrels and colugos. Maiopatagium and Vilevolodon, described concurrently, offer clues to the ways various synapsids have taken to the skies over evolutionary time scales. A second species, M. sibiricum, was described from the Bathonian aged Itat Formation in 2019
Archisargidae is an extinct family of brachyceran flies known from the Jurassic and Cretaceous periods. It is part of the extinct superfamily Archisargoidea. Most members of the family are known from the Callovian-Oxfordian Daohugou biota of Inner Mongolia, China, and the equivalently aged Karabastau Formation of Kazakhstan. The family has been found to be paraphyletic with respect to Eremochaetidae in a cladistic analysis.
