Callichirus is a genus of crustaceans belonging to the family Callianassidae. [1] It was circumscribed by William Stimpson in 1866.
The genus includes the following species:
Aepisaurus was a genus of sauropod dinosaur from the Albian-age Lower Cretaceous Grès vert of Départment du Vaucluse, France, around 100.5 million years ago. It is an obscure genus from an unknown family, represented by a single humerus, now partly lost. Despite its lack of popularity, or perhaps because of it, it has been misspelled several ways in the scientific literature, with multiple dates given to the year of description as well.
Tarascosaurus is a genus of abelisaurid, theropod dinosaur from Late Cretaceous of France.
Hypselosaurus is a dubious genus of titanosaurian sauropod that lived in southern France during the Late Cretaceous, approximately 70 million years ago in the early Maastrichtian. Hypselosaurus was first described in 1846, but was not formally named until 1869, when Phillip Matheron named it under the binomial Hypselosaurus priscus. The holotype specimen includes a partial hindlimb and a pair of caudal vertebrae, and two eggshell fragments were found alongside these bones. Because of the proximity of these eggshells to the fossil remains, many later authors, including Matheron and Paul Gervais, have assigned several eggs from the same region of France all to Hypselosaurus, although the variation and differences between these eggs suggest that they do not all belong to the same taxon. Hypselosaurus has been found in the same formation as the dromaeosaurids Variraptor and Pyroraptor, the ornithopod Rhabdodon, and the ankylosaurian Rhodanosaurus, as well as indeterminate bones from other groups.
Betasuchus is a genus of theropod dinosaur which lived during the Late Cretaceous Period. Betasuchus is, besides Orthomerus, the only dinosaur genus named from remains found in the Netherlands and the only non-avian theropod found in the Maastrichtian Beds.
Bradycneme is a genus of theropod dinosaur from the Maastrichtian-age Upper Cretaceous Sânpetru Formation of the Hațeg Basin, Transylvania, Romania. It is known only from a partial right lower leg, which its original describers believed came from a giant owl.
Elopteryx is a genus of, perhaps troodontid, maniraptoran theropod dinosaur based on fragmentary fossils found in late Cretaceous Period rocks of Romania. The single species, Elopteryx nopcsai, is known only from very incomplete material, and therefore is considered a nomen dubium by most paleontologists.
Neosodon was a genus of sauropod dinosaur from the Late Tithonian-age Upper Jurassic Sables et Gres a Trigonia gibbosa of Départment du Pas-de-Calais, France. It has never been formally given a species name, but is often seen as N. praecursor, which actually comes from a different animal. Often in the past, it had been assigned to the wastebasket taxon Pelorosaurus, but restudy has suggested that it could be related to Turiasaurus, a roughly-contemporaneous giant Spanish sauropod. It is only known from six teeth.
Variraptor is a genus of coelurosaurian theropod dinosaur from the Late Cretaceous of France.
Heptasteornis is the name given to a dubious genus of small dinosaur from the Late Cretaceous. The type species is Heptasteornis andrewsi, described as a presumed gigantic prehistoric owl in 1975. It was previously included in Elopteryx nopcsai and indeed the holotypes of both were believed to be from the same individual as they were discovered, and initially were assigned the same specimen number. This appears to be in error however.
Iuticosaurus is a genus of titanosaur sauropod dinosaur from the Early Cretaceous of the Isle of Wight. Two species have been named: I. valdensis and I. lydekkeri. I. valdensis was found in the Wessex Formation and I. lydekkeri in the younger Upper Greensand.
Lirainosaurus is a genus of titanosaur sauropod which lived in what is now Spain. The type species, Lirainosaurus astibiae, was described by Sanz, Powell, Le Loeuff, Martinez, and Pereda-Suberbiola in 1999.
Upogebia is a genus of mud shrimp, in the family Upogebiidae, containing the following species:
Callianassidae is a family of ghost shrimp of the order Decapoda.
Callianassa is a genus of mud shrimps, in the family Callianassidae. Three of the species in this genus have been split off into a new genus, Pestarella, while others such as Callianassa filholi have been moved to Biffarius.
Basilochelys is an extinct genus of land turtle which existed during the early Cretaceous period (Berriasian). Containing the sole species Basilochelys macrobios, its fossils have been found in the Phu Kradung Formation of Northeast Thailand. It is considered to be the most basal member of the group Trionychoidae.
The Calcaire de Valognes is an Early Jurassic (Hettangian) geologic formation in France. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
Tsintaosaurini is a tribe of basal lambeosaurine hadrosaurs native to Eurasia. It currently contains only Tsintaosaurus and Pararhabdodon . Koutalisaurus, also known from late Cretaceous Spain and formerly referred to Pararhabdodon, may also be a tsintaosaurin because of its association with the latter genus; some recent work also suggests it may indeed be referrable to Pararhabdodon.
Normanniasaurus is an extinct genus of basal titanosaur sauropod known from the Early Cretaceous Poudingue Ferrugineux of Seine-Maritime, northwestern France.
Clausidium dissimile is a species of copepod that has been found along the Atlantic and Gulf Coasts from Massachusetts to Florida. They are found on the bodies of mud shrimp of the family Callianassidae, or from water collected from mud shrimp burrows.
Callichirus major sensu lato is a monophyletic species complex of ghost shrimp in the infraorder Axiidea, found in flat sandy beaches across the Pan-American coastline.
