An exceptionally preserved Jurassic skink suggests lizard diversification preceded fragmentation of Pangaea

  title={An exceptionally preserved Jurassic skink suggests lizard diversification preceded fragmentation of Pangaea},
  author={Mateusz Tałanda},
The present distribution of lizards is usually explained as a result of relatively recent global events, i.e. faunal turnovers or exchanges within and between particular continents mostly connected with glaciations and land‐bridges. However, today's disjunct distribution of the North American Xantusiidae and African Cordyliformes (close relatives of skinks) does not fit generally accepted biogeographical patterns. A new, exquisitely preserved specimen of the Late Jurassic lizard Ardeosaurus… 

A new gecko (Squamata, Gekkota) from the Eocene of Geiseltal (Germany) implies long‐term persistence of European Sphaerodactylidae

The skull of G. delfinoi represents one of the most complete and oldest fossil geckos from the Cenozoic and warrants the naming of a new taxon, Geiseleptes delfinoi gen. et sp.

Evolution of diel activity patterns in skinks (Squamata: Scincidae), the world's second‐largest family of terrestrial vertebrates

This work uses phylogenetic comparative methods to examine the evolutionary history of diel activity in skinks and examines how diel patterns are associated with microhabitat, ambient temperatures, and morphology, and found support for a nondiurnal ancestral skink.



The early Cretaceous lizard genus Yabeinosaurus from China: Resolving an enigma

Phylogenetic analysis highlights some of the difficulties involved in determining the systematic positions of early squamate taxa and suggests a position close to the iguanian‐scleroglossan dichotomy (just above or just below) in Yabeinosaurus.

Fossil lizards and snakes from Ano Metochi – a diverse squamate fauna from the latest Miocene of northern Greece

Abstract We here describe a new squamate fauna from the late Miocene (Messinian, MN 13) of Ano Metochi, northern Greece. The lizard fauna of Ano Metochi is here shown to be rather diverse, consisting

Eocene Lizards of the Clade Geiseltaliellus from Messel and Geiseltal, Germany, and the Early Radiation of Iguanidae (Reptilia: Squamata)

The presence of Geiseltaliellus in Europe during the warm, humid Eocene suggests dispersal from North America and a more northerly distribution of the corytophanine stem than the crown.

A gravid lizard from the Cretaceous of China and the early history of squamate viviparity

This specimen documents the first occurrence of viviparity in a fossil reptile that was largely terrestrial in life, and extends the temporal distribution of the trait in squamates by at least 30 Ma.

A stem acrodontan lizard in the Cretaceous of Brazil revises early lizard evolution in Gondwana

A new lizard species presented herein is the first acrodontan from South America, indicating acRodontans radiated throughout Gondwana much earlier than previously thought, and that some of the first South American lizards were more closely related to their counterparts in Africa and Asia than to the modern fauna of South America.

Osteology, phylogeny, and functional morphology of two Jurassic lizard species and the early evolution of scansoriality in geckoes

The first detailed morphological description, species-level phylogeny, and functional morphological evaluation of E. schroederi and A. digitatellus is provided, corroborate their initial placement as geckoes (stem gekkotans, more specifically), and illustrate a number of climbing adaptations that indicate the early evolution of scansoriality in gekKonomorph lizards.


The discovery of the first unequivocal record of a pre-Late Pleistocene lizard from the island of Madagascar indicates that cordylids, after their occurrence in the Maastrichtian, became extinct on Madagascar, leaving only zonosaurine Gerrhosauridae as extant representatives of Cordyliformes on the island.

The molecular evolutionary tree of lizards, snakes, and amphisbaenians.

A tiny lizard (Lepidosauria, Squamata) from the Lower Cretaceous of Spain

A new squamate taxon is described on the basis of an articulated skeleton from the Early Cretaceous Spanish lagerstatten of Las Hoyas, which differs from other known Mesozoic lizards in combining very small body size with a short rostrum, low maxillary tooth count, a relatively slender and elongated body, and short limbs with large hind feet.

Fossil lizards from the Jurassic Kota Formation of India

A lizard assemblage from the Upper Member of the Kota Formation of peninsular India, usually considered to be of Early–Middle Jurassic age, is reported, providing evidence that iguanians had begun to diversify before the break-up of Pangea.
