The Ellisdale Fossil Site is located near Ellisdale in the valley of the Crosswicks Creek, in Monmouth County, New Jersey, United States.The site has produced the largest and most diverse fauna of Late Cretaceous terrestrial animals from eastern North America, including the type specimens of the teiid lizard Prototeius stageri [1] and the batrachosauroidid salamander Parrisia neocesariensis.

The famous Ellisdale Fossil Site, a konzentrat-lagerstätten which contains one of the most diverse Cretaceous vertebrate assemblages (likely rapidly buried in a massive flood event) known from eastern North America/former Appalachia, is an exposure of this formation.
Currently there are about 40 extant families of Lacertilia.These vary considerably, e.g. in shades, colours, and sizes. For example, the largest representative among Geckos, the New Caledonian giant gecko (Rhacodactylus leachianus), has a length of up to 36 cm (14 in), while the largest species in the family Varanidae, Komodo dragon (Varanus komodoensis), has a length up to 3 metres (10 ft ...
A study on the evolution of tooth complexity in squamates, based on data from extant and fossil taxa, is published by Lafuma et al. (2021). [21]A study on the diversity of jaw sizes, lower jaw shape and morphology of teeth in Cretaceous squamates is published by Herrera-Flores, Stubbs & Benton (2021), who interpret their findings as indicating that a substantial expansion of ecomorphological ...
Most lizard species and some snake species are insectivores. The remaining snake species, tuataras, and amphisbaenians, are carnivores. While some snake species are generalist, others eat a narrow range of prey - for example, Salvadora only eat lizards. [33] The remaining lizards are omnivores and can consume plants or insects. The broad ...
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 Gymnopthalmidae , and both families comprise the Teiioidea.
Anguidae refers to a large and diverse family of lizards native to the Northern Hemisphere.Common characteristics of this group include a reduced supratemporal arch, striations on the medial faces of tooth crowns, osteoderms, and a lateral fold in the skin of most taxa. [1]
Dactyloidae are a family of lizards commonly known as anoles (US: / ə ˈ n oʊ. l i z / ⓘ) and native to warmer parts of the Americas, ranging from southeastern United States to Paraguay. [1] [2] Instead of treating it as a family, some authorities prefer to treat it as a subfamily, Dactyloinae, of the family Iguanidae.
