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'' and other members of 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.

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 r ... [...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 (geology), 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 enantiornithes, enantiornithines.Weishampel et al., 2004, pp.556-563 The lithology of the formation mostly consists of Lacustrine deposits, lacustrine limestone deposited in a freshwater wetland environment. Las Hoyas Taphonomy As a Lagerstätte#Important Konservat-Lagerstätten, 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, ...

Wessex Formation
The Wessex Formation is a fossil-rich England, English geological formation that dates from the Berriasian to Barremian Stage (stratigraphy), stages 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 Historically, the Wessex Formation has been called alternately the "Variegated Marls and Sandstones", a name used by William Joscelyn Arkell, 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 ...

Barremian
The Barremian is an age in the geologic timescale (or a chronostratigraphic stage) between 125.77 Ma (million years ago) and 121.4 ± 1.0 Ma (Historically, this stage was placed at 129.4 million to approximately 125 million years ago) 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 '' Paradesh ...

Robert Julien Hoffstetter (11 June 1908 in Fargniers – 29 December 1999 in Gennevilliers) was a French taxonomist and herpetologist who was influential in categorizing reptiles Reptiles, as commonly defined, are a group of tetrapods with an ectothermic metabolism and Amniotic egg, amniotic development.

Teiidae
Teiidae is a family of lacertoidean 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 Gymnophthalmidae, Gymnopthalmidae, and both families comprise the Teiioidea. The Teiidae includes several Parthenogenesis, parthenogenic species – a mode of clonal reproduction. Presently, the Teiidae consists of approximately 150 species in eighteen genus, genera. Morphology and behavior Teiids can be distinguished from other lizards by the following characteristics: large rectangular scale (zoology), scales that form distinct transverse rows Anatomical terms of location#Dorsal and ventral, ventrally and generally small granular scale (zoology), scales Dorsum (anatomy), dorsally, head scales that are separate from the skull bones, and teeth that are solid at the base and "glued" to the jaw bones. Additionally, all teiids have a forked, snake-like tongue. They all possess we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Pa ... 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 143.1 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 77.1 million years, it is the ninth and longest geological period of the entire Phanerozoic. The name is derived from the Latin , 'chalk', which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation . 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 largely ice-free, although there is some evidence of brief periods of glaciation during the cooler first half, and forests extended to the poles. Many of the dominant taxonomic groups present in modern times can be ultimately traced back to origins in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
