Camarillasaurus
''Camarillasaurus'' (meaning " Camarillas lizard") is a genus of spinosaurid dinosaur from the Early Cretaceous period (Barremian) of Camarillas, Teruel Province, in what is now northeastern Spain. Described in 2014, it was originally identified as a ceratosaurian theropod, before being referred to the Spinosauridae in 2021. History of research Fossils of ''Camarillasaurus'' were discovered in the Camarillas Formation. The type species, ''Camarillasaurus cirugedae'', was described by palaeontologists Bárbara Sánchez-Hernández and Michael J. Benton. The describers considered it to be a basal ceratosaur, somewhat unusual given its young age. However, in an abstract given at the EAVP 2019 conference, Oliver Rauhut and colleagues suggested it is a member of the Spinosauridae rather than a ceratosaur, based on characters of the posterior caudal vertebrae and newly excavated material at the type locality; a chapter of a 2019 dissertation by Adun Samathi concurred with that conclu ...

Camarillas Formation
The Camarillas Formation is a geological formation in the Teruel Province of Aragón, Spain whose strata date back to the Early Cretaceous (Barremian stage). The sandstones, mudstones and conglomerates of the formation, that due to syn-sedimentary faulting varies greatly in thickness from , were deposited in fluvial, deltaic and lacustrine environments. The formation was deposited in the Galve Sub-basin of the Maestrazgo Basin in central-eastern Spain. During deposition, Iberia was an island, separated by seas from North Africa and France. Underlying the Camarillas Formation is the also highly fossiliferous El Castellar Formation and the Artoles Formation rests on top of the formation.Herrero Gascón & Pérez Lorente, 2009, p.68 The Camarillas Formation has provided a rich fossil assemblage of fossils of mammals, snakes, turtles, crocodylians, fish, dinosaurs and their eggs. Various tracksites of families of dinosaurs exist in the formation. Dinosaur remains have been rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baryonyx
''Baryonyx'' () is a genus of theropod dinosaur which lived in the Barremian stage of the Early Cretaceous period, about 130–125 million years ago. The first skeleton was discovered in 1983 in the Smokejack Clay Pit, of Surrey, England, in sediments of the Weald Clay Formation, and became the holotype specimen of ''Baryonyx walkeri'', named by palaeontologists Alan J. Charig and Angela C. Milner in 1986. The generic name, ''Baryonyx'', means "heavy claw" and alludes to the animal's very large claw on the first finger; the specific name, ''walkeri'', refers to its discoverer, amateur fossil collector William J. Walker. The holotype specimen is one of the most complete theropod skeletons from the UK (and remains the most complete Spinosaurid), and its discovery attracted media attention. Specimens later discovered in other parts of the United Kingdom and Iberia have also been assigned to the genus, though many have since been moved to new genera. The holotype specimen, whic ...

Vallibonavenatrix
''Vallibonavenatrix'' (meaning "Vallibona huntress" after the town near where its remains were found) is a genus of spinosaurid dinosaur from the Early Cretaceous (Barremian) Arcillas de Morella Formation of Castellón, Spain. The type and only species is ''Vallibonavenatrix cani'', known from a partial skeleton. Discovery and naming During the late 1980s and early 1990s, amateur fossil collector Juan Cano Forner was recovering bones from various localities in Els Ports Natural Park, located in the Province of Castellón, Spain. In one of these—the Santa Águeda locality in the town of Vallibona—he excavated numerous vertebrate remains dating to the Mesozoic era, among which were dinosaur fossils. Forner housed these fossils in a private collection at Sant Mateu, which the Generalitat Valenciana acknowledged as a museographic collection in 1994. In 2007, the Spanish palaeontologist Fernando Gómez-Fernández and colleagues published a provisional description on the pel ...

Iberospinus
''Iberospinus'' or (meaning " Iberian spine") is an extinct genus of spinosaurid dinosaur from the Early Cretaceous (Barremian) Papo Seco Formation of Portugal. The genus contains a single species, ''I. natarioi'', known from several assorted bones belonging to one individual. ''Iberospinus'' represents one of three known spinosaurid taxa from the Iberian Peninsula, the others being ''Vallibonavenatrix'', and ''Camarillasaurus''. It is important for its implications of the geographical origin of Spinosauridae and the suggested presence of an at least semi-aquatic lifestyle early in the evolution of this clade. Discovery and naming The first fossil material was discovered in 1999, with additional expeditions from 2004 to 2008. After being described as a specimen of ''Baryonyx'' in 2011, it was realised to have been a unique species in 2019. Additional material was discovered in a June 2020 expedition, after which ''Iberospinus'' was described as a new genus and species in 2022 ...

Taxon
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
