Meyasaurus
''Meyasaurus'' is an extinct genus of Teiid lizard known from the Barremian of Spain and the Isle of Wight, UK. Four species are known from Spain, from the La Huérguina, Camarillas, and La Pedrera de Rúbies Formations while an indeterminate taxon is known from the Wessex Formation of Isle of Wight. It is a possible close relative of ''Barbatteius ''Barbatteius'' is an extinct genus of teiid lizard represented by the type species ''Barbatteius vremiri'' from the Late Cretaceous of Romania.

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 ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Huérguina Formation
The La Huérguina Formation (also known as the Calizas de La Huérguina Formation, La Huérguina Limestone Formation or as the Una Formation) is a geological formation in Spain whose strata date back to the Barremian stage of the Early Cretaceous.Martínez et al., 2017 Las Hoyas is a Konservat-Lagerstätte within the formation, located near the city of Cuenca, Spain. The site is mostly known for its exquisitely preserved dinosaurs, especially enantiornithines.Weishampel et al., 2004, pp.556-563 The lithology of the formation mostly consists of lacustarine limestone deposited in a freshwater wetland environment. Las Hoyas Taphonomy As a Konservat-Lagerstätten, the preservation is exceptional. This may be a result of three factors: Microbial mats, Obruption and Stagnation. Microbial mats may be responsible for the preservation of soft tissue in many fossils from Las Hoyas, like ''Pelecanimimus''' crest. The iron carbonate depositions, a result from bacterial metabolism which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wessex Formation
The Wessex Formation is a fossil-rich English geological formation that dates from the Berriasian to Barremian stages (about 145–125 million years ago) of the Early Cretaceous. It forms part of the Wealden Group and underlies the younger Vectis Formation and overlies the Durlston Formation. The dominant lithology of this unit is mudstone with some interbedded sandstones. It is part of the strata of the Wessex Basin, exposed in both the Isle of Purbeck and the Isle of Wight. While the Purbeck sections are largely barren of vertebrate remains, the Isle of Wight sections are well known for producing the richest and most diverse fauna in Early Cretaceous Europe. Nomenclatural History The Wessex Formation has historically alternately been called the "Variegated Marls And Sandstones", a name used by W. J. Arkell in his 1947 map of the Isle of Purbeck as well as the "Wealden Marls" It was given its current formal name by Daley and Stewart in 1979 Stratigraphy and Lithology ...

Barbatteiidae
Barbatteiidae is an extinct family of lizards, endemic to the paleoisland Hațeg Island in the Tethys Ocean during the final stages of the Cretaceous, In what is now Romania.

Barremian
The Barremian is an age in the geologic timescale (or a chronostratigraphic stage) between 129.4 ± 1.5 Ma ( million years ago) and 121.4 ± 1.0 Ma). It is a subdivision of the Early Cretaceous Epoch (or Lower Cretaceous Series). It is preceded by the Hauterivian and followed by the Aptian Stage.See Gradstein ''et al.'' (2004) or the online geowhen database (link below) Stratigraphic definitions The original type locality for the Barremian Stage is in the vicinity of the village of Barrême, Alpes-de-Haute-Provence, France. Henri Coquand defined the stage and named it in 1873. The base of the Barremian is determined by the first appearance of the ammonites ''Spitidiscus hugii'' and ''Spitidiscus vandeckii''. The end of the Barremian is determined by the geomagnetic reversal at the start of the M0r chronozone, which is biologically near the first appearance of the ammonite '' Paradeshayesites oglanlensis''.

Teiidae
Teiidae is a family of autarchoglossan lizards native to the Americas. Members of this family are generally known as whiptails or racerunners; however, tegus also belong to this family. Teiidae is sister to the Gymnopthalmidae, and both families comprise the Teiioidea. The Teiidae includes several parthenogenic species – a mode of clonal reproduction. Presently, the Teiidae consists of approximately 150 species in eighteen genera. Morphology and behavior Teiids can be distinguished from other lizards by the following characteristics: they have large rectangular scales that form distinct transverse rows ventrally and generally small granular scales dorsally, they have head scales that are separate from the skull bones, and the teiid teeth are solid at the base and "glued" to the jaw bones. Additionally, all teiids have a forked, snake-like tongue. They all possess well-developed limbs. Teiids are all terrestrial (few are semi-aquatic) and diurnal, and are primarily carni ...

Barbatteius
''Barbatteius'' is an extinct genus of teiid lizard represented by the type species ''Barbatteius vremiri'' from the Late Cretaceous of Romania. ''B. vremiri'' was named in 2016 on the basis of a well preserved skull from the Haţeg Basin and differs from other teiids in having more prominent osteoderms covering the skull roof. It is also large for a teiid, with an estimated total body length of . ''Barbatteius'' lived on Haţeg Island during the early Maastrichtian stage and was part of an isolated island fauna. However, its close affinities with teiids from Gondwana and its co-occurrence with paramacellodid and borioteiioid lizards from Euramerica Laurasia () was the more northern of two large landmasses that formed part of the Pangaea supercontinent from around ( Mya), the other being Gondwana. It separated from Gondwana (beginning in the late Triassic period) during the breakup of Pan ... suggests that Haţeg Island was colonized by lizards multiple times from many d ...

Cretaceous Lizards
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth by t ...
