The affinities of three problematic groups of elongate, burrowing reptiles (amphisbaenians, dibamids and snakes) are reassessed through a phylogenetic analysis of all the major groups of squamates, including the important fossil taxaSineoamphisbaena, mosasauroids andPachyrhachis; 230 phylogenetically informative osteological characters were evaluated in 22 taxa. Snakes (includingPachyrhachis) are anguimorphs, being related firstly to large marine mosasauroids, and secondly to monitor lizards… 

ON THE PHYLOGENETIC RELATIONSHIPS OF THE CRETACEOUS SNAKES WITH LEGS, WITH SPECIAL REFERENCE TO PACHYRHACHIS PROBLEMATICUS (SQUAMATA, SERPENTES)

TLDR
Several aspects of character delimitations as proposed by Caldwell are reviewed, and corroborate the macrostomatan affinities of Pachyrhachis.

Phylogeny and evolution of head shape in the Amphisbaenia (Reptilia: Squamata)

TLDR
This study aims to understand the evolution of head forms within Amphisbaenia, testing whether these forms have a phylogenetic or environment relationship, and if they are morphological convergences, and aims to investigate and contribute to fill gaps in the knowledge of this group.

Phylogeny And Systematics Of Squamata (Reptilia) Based On Morphology

TLDR
This study examines squamate relationships using 222 ingroup taxa scored for 363 morphological characters and confirms the monophyly of the clades Scleroglossa (extant squamates exclusive of Iguania), Gekkota, Scincomorpha, Lacertoidea,ScincoideA, Anguimorpha and Varanoidea.

Snake phylogeny based on osteology, soft anatomy and ecology

Relationships between the major lineages of snakes are assessed based on a phylogenetic analysis of the most extensive phenotypic data set to date (212 osteological, 48 soft anatomical, and three

Squamate phylogeny, taxon sampling, and data congruence

Molecular phylogenetics of squamata: the position of snakes, amphisbaenians, and dibamids, and the root of the squamate tree.

TLDR
A molecular phylogenetic study of 69 squamate species suggests that similar states in Sphenodon and Iguania result from homoplasy, and species previously placed in Scleroglossa, Varanoidea, and several other higher taxa do not form monophyletic groups.

Phylogenetic Affinities of the Rare and Enigmatic Limb-Reduced Anelytropsis (Reptilia: Squamata) as Inferred with Mitochondrial 16S rRNA Sequence Data

TLDR
A monophyletic Dibamidae composed of these two genera is supported by molecular data for the first time and several relationships in the inferred tree, although weakly supported, were congruent with those found in previous molecular phylogenetic analyses.

A combined evidence phylogenetic analysis of Anguimorpha (Reptilia: Squamata)

TLDR
It is found that a global combined evidence analysis (GCA) does not recover a holophyletic Varanoidea, but omission of fossil taxa reveals cryptic molecular support for that group.

Classification and phylogeny of the diapsid reptiles

  • M. Benton
  • Environmental Science, Geography
  • 1985
TLDR
A cladistic analysis of skull and skeletal characters of all described Permo-Triassic diapsid reptiles suggests some significant rearrangements to commonly held views of the Diapsida.

Squamate phylogeny and the relationships of snakes and mosasauroids

TLDR
Cladistic analysis of extant and fossil squamates finds the fossil squamate, Coniasaurus Owen, 1850, to be the sister-group of the Mosasauroidea (mosasaurs and aigialosaurs), and Pythonomorpha is supported in all 18 shortest cladograms.

A reevaluation of early amniote phylogeny

TLDR
It is indicated that three major clades of amniotes extend from the present to the Palaeozoic, and these three clades are the Synapsida (including Mammalia), Parareptilia (including Testudines), and Eureptili (including Sauria).

The relationships of the Lizard genera Anelytropsis and Dibamus

TLDR
The similarity between Anelytropsis and Dibamus in derived character states is so extensive and detailed that it is obvious they are each other's closest living relatives and warrant grouping in one family, the Dibamidae.

Huehuecuetzpalli mixtecus gen. et sp. nov: a basal squamate (Reptilia) from the Early Cretaceous of Tepexi de Rodriguez, central Mexico

TLDR
Although its appearance is late in the fossil record of lizards, Huehuecuetzpalli is the first report of a basal squamate and provides important information on early transformation of characters in lizard evolution.

Cladistic relationships in the Gekkonoidea (Squamata, Sauria)

TLDR
A strictly monophylctic classititation is proposed, and a most parsimonious hypothesis contains srvel-a1 well-corroborated tladcs and the absence of the second cer;~tobr.

Sineoamphisbaena hexatabularis, an amphisbaenian (Diapsida: Squamata) from the Upper Cretaceous redbeds at Bayan Mandahu (Inner Mongolia, People's Republic of China), and comments on the phylogenetic relationships of the Amphisbaenia

Sineoamphisbaena hexatabularis Wu et al., 1993 is the earliest known amphisbaenian represented by well-preserved cranial and postcranial material. It reveals a mosaic of generalized lizard-like

Anatomy and relationships of Pachyrhachis problematicus, a primitive snake with hindlimbs

TLDR
Pachyrhachis provides additional support for the hypothesis that snakes are most closely related to Cretaceous marine lizards (mosasauroids), and is shown to be the most primitive snake, and the sister–group to all other snakes.

A new lizard‐like reptile (Diapsida: Lepidosauromorpha) from the Middle Jurassic of England

TLDR
The skull of a new diapsid reptile, Marmorelta oxoniensis, which was common within the fauna is described and it is concluded that Marmoretta was a lepidosauromorph, most probably the sister taxon of Lepidosauria.

Evolutionary History of the South American Microteiid Lizards (Teiidae: Gymnophthalminae)

TLDR
The distributional patterns of the microteiids are examined in light of the geologic history of the South American continent and four major areas of association are postulated with recurrent dispersal into available habitat.
