Eucamerotus (meaning "well-chambered" in reference to the hollows of the vertebrae) was a genus of sauropod dinosaur from the Barremian-age Lower Cretaceous Wessex Formation (Wealden) of the Isle of Wight, England.
Temporal range: Lower Cretaceous
John Hulke erected the genus in 1872 for NHMUK R.2522, a neural arch found by William D. Fox near Brighstone Bay, but provided no species name. He considered the Ornithopsis hulkei lectotype referable to the genus. He later referred NMHUK R.2522 to Ornithopsis, synonymizing Eucamerotus with Seeley's name based on the discovery of additional vertebrae from the Isle of Wight. Later authors treated Eucamerotus as a synonym of Pelorosaurus.
William T. Blows resurrected the genus in 1995 as a valid brachiosaurid, added the specific name and added the species epithet foxi, designating the various vertebrae that Hulke (1879, 1880) had referred to Ornithopsis as paratypes, while referring additional vertebrae and partial skeleton MIWG-BP001 to it. This last point has not been generally accepted; unfortunately, this skeleton has never been officially described.
Naish and Martill (2001) suggested Eucamerotus was a dubious brachiosaurid, and did not find Blows' characters convincing. Upchurch et al. (2004) considered it to be a dubious sauropod. However, a more recent review of Wealden sauropods from England places Eucamerotus as a valid genus of Titanosauriformes incertae sedis.
The vertebrae are around twenty centimetres long. If a brachiosaurid, Eucamerotus may have been around 15 m (49.2 ft) long, small for a sauropod. As any kind of sauropod, it would have been a quadrupedal herbivore.
Apatosaurinae is the name of a subfamily of diplodocid sauropods that existed between 157 and 150 million years ago in North America. The group includes two genera for certain, Apatosaurus and Brontosaurus, with at least five species. Atlantosaurus and Amphicoelias might also belong to this group.Below is a cladogram of apatosaurinae interrelationships based on Tschopp et al., 2015.Argyrosauridae
Argyrosauridae is a family of large titanosaurian dinosaurs known from the late Cretaceous period of Argentina and Egypt. The group has been recovered as monophyletic, including the type genus Argyrosaurus as well as Paralititan.Astrophocaudia
Astrophocaudia is a genus of somphospondylan sauropod known from the late Early Cretaceous (Albian stage) of Texas, United States. Its remains were discovered in the Trinity Group. The type species is Astrophocaudia slaughteri, described in 2012 by Michael D. D’Emic while a doctoral student at the Museum of Paleontology of the University of Michigan, USA.Brasilotitan
Brasilotitan is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous (early Maastrichtian) Adamantina Formation of Brazil. The type species is Brasilotitan nemophagus.Cedarosaurus
Cedarosaurus (meaning "Cedar lizard" - named after the Cedar Mountain Formation, in which it was discovered) was a nasal-crested macronarian dinosaur genus from the Early Cretaceous Period (Barremian). It was a sauropod which lived in what is now Utah. It was first described by Tidwell, Carpenter and Brooks in 1999.It shows similarities to the brachiosaurid Eucamerotus from the Wessex Formation of southern England, as well as to Brachiosaurus from the Morrison Formation.Cetiosauridae
Cetiosauridae is a family of sauropod dinosaurs. While traditionally a wastebasket taxon containing various unrelated species, some recent studies have found that it may represent a natural clade. Additionally, at least one study has suggested that the mamenchisaurids may represent a sub-group of the cetiosaurids, which would be termed Mamenchisaurinae.Daxiatitan
Daxiatitan is a genus of titanosaur dinosaur from the Lower Cretaceous of Lanzhou Basin, Gansu Province, northwestern China. It is known from fossils including several neck vertebrae, a shoulder blade, and a thigh bone.It was a very large dinosaur, estimated at 23–30 meters (75–98 feet). Like both Euhelopus and Huanghetitan, it had an enormously long neck.Diplodocinae
Diplodocinae is an extinct subfamily of diplodocid sauropods that existed from the Late Jurassic to Early Cretaceous of North America, Europe and South America, about 161.2 to 136.4 million years ago. Genera within the subfamily include Tornieria, Supersaurus, Leinkupal, Galeamopus, Diplodocus, Kaatedocus and Barosaurus.Cladogram of the Diplodocidae after Tschopp, Mateus, and Benson (2015).Eomamenchisaurus
Eomamenchisaurus (meaning "dawn Mamenchisaurus") is a genus of mamenchisaurid sauropod dinosaur from the Middle Jurassic of Yuanmou, Yunnan, China. The type species is E. yuanmouensis, described by Lü Junchang et al. in 2008.Ferganasaurus
Ferganasaurus was a genus of dinosaur first formally described in 2003 by Alifanov and Averianov. The type species is Ferganasaurus verzilini. It was a sauropod similar to Rhoetosaurus. The fossils were discovered in 1966 in Kyrgyzstan from the Balabansai Formation and date to the Callovian stage of the Middle Jurassic.Flagellicaudata
Flagellicaudata is a clade of Dinosauria. It belongs to Sauropoda and includes two families, the Dicraeosauridae and the Diplodocidae.Gravisauria
Gravisauria is a clade of sauropod dinosaurs consisting of some genera, Vulcanodontidae and Eusauropoda.Huangshanlong
Huangshanlong is a genus of mamenchisaurid dinosaurs native to the Anhui province of China. It contains a single species, Huangshanlong anhuiensis. H. anhuiensis represents, along with Anhuilong and Wannanosaurus, one of three dinosaurs fround in Anhui province.Kaijutitan
Kaijutitan (meaning "Kaiju titan" after the type of Japanese movie monsters) is a genus of basal titanosaur dinosaur from the Sierra Barrosa Formation from Neuquén Province in Argentina. The type and only species is Kaijutitan maui.Ornithopsis
Ornithopsis (meaning "bird-likeness") was a medium-sized Early Cretaceous sauropod dinosaur, from England.Tambatitanis
Tambatitanis is an extinct genus of titanosauriform dinosaur from the Early Cretaceous (probably early Albian) of Japan. It is known from a single type species, Tambatitanis amicitiae. It was probably around 14 meters long and its mass was estimated at some 4 tonnes. It was a basal titanosauriform and possibly belonged to the Euhelopodidae.Tastavinsaurus
Tastavinsaurus is a genus of sauropod dinosaur belonging to the Titanosauriformes. It is based on a partial skeleton from the Early Cretaceous of Spain. The type species is Tastavinsaurus sanzi, named in honor of the Rio Tastavins in Spain and Spanish paleontologist José Luis Sanz.Tengrisaurus
Tengrisaurus (meaning "Tengri lizard") is a genus of lithostrotian sauropod, from the Early Cretaceous (Barremian-Aptian), of the Murtoi Formation, Russia. It was described in 2017 by Averianov & Skutschas. The type species is T. starkovi.William Fox (palaeontologist)
William D. Fox (9 August 1813 – 1881) was an English clergyman and palaeontologist who worked on the Isle of Wight and made some significant discoveries of dinosaur fossils.
The Reverend William D. Fox was born in Cumberland. He moved to the Isle of Wight in 1862 to take up the post of curate at the Parish church of St Mary the Virgin in Brixton (now known as Brighstone). He resigned his post in 1867 but continued to live in the area to carry on his collecting. In 1875, he became curate of nearby Kingston, near Shorwell.Although lacking formal scientific training Fox was remarkably astute and discussed his findings with eminent palaeontologists of the day including John Hulke (1830-1895) and Sir Richard Owen. Fox had easy access to Brighstone Bay from his home, Myrtle Cottage in Brighstone, and so spent many an hour collecting fossils, much to the detriment of his pastoral work; in fact, it was said of him at the time, by the wife of the vicar, that it was "always bones first and the parish next". He is also quoted as having written in a letter to Owen "I cannot leave this place while I have any money left to live on, I take such deep [sic] in hunting for old dragons".In 1882 Fox's collection of more than 500 specimens was acquired by the Natural History Museum after his death.Fox is credited with the finding of several species, most described by his friend Owen, and named by him after their finder. These include Polacanthus foxii, Hypsilophodon foxii, Eucamerotus foxi, Iguanodon foxii, Calamosaurus foxii (formerly Calamospondylus) and Aristosuchus.
