Phylogenetic relationships within squamata

AMNIOTE PHYLOGENY AND THE IMPORTANCE OF FOSSILS
TLDR
The importance of the critical fossils seems to reside in their relative primitive‐ness, and the simplest explanation for their more conservative nature is that they have had less time to evolve.
Assembling the Squamate Tree of Life: Perspectives from the Phenotype and the Fossil Record
TLDR
This study relied on traditionally prepared specimens as well as high-resolution computed tomography scans that afforded unprecendented access to the cranial anatomy of Squamata to provide an unparalleled sample of the phenotype enabling it to more fully explore the extreme incongruences between molecular and morphological topologies for the squamate tree of life.
DEVELOPING A PROTOCOL FOR THE CONVERSION OF RANK-BASED TAXON NAMES TO PHYLOGENETICALLY DEFINED CLADE NAMES, AS EXEMPLIFIED BY TURTLES
TLDR
This work may provide a useful road map to those intent on converting their traditional rank-based nomenclatures to explicitly phylogenetic nomenClatures under the precepts of the PhyloCode.
Phylogeny as a Central Principle in Taxonomy: Phylogenetic Definitions of Taxon Names
Defining the names of taxa in terms of common ancestry, that is, using phylogenetic definitions of taxon names, departs from a tradition of character-based definitions by granting the concept of…
A phylogenetic analysis of lepidosauromorpha
TLDR
This paper analyzes phylogenetic relationships within a subtaxon of Sauna, the Lepidosauromorpha, and attempts to stabilize the concept of each lepidosauromorph taxon with as rigorous a diagnosis as the natiu-e of the material allows.
Fossil xenosaurid and anguid lizards from the early Eocene Wasatch Formation, Southeast Wyoming, and a revision of the Anguioidea
The origin of snakes: revealing the ecology, behavior, and evolutionary history of early snakes using genomics, phenomics, and the fossil record
TLDR
Although the snake crown-group most likely arose on the supercontinent of Gondwana, the results suggest the possibility that the snake total-group originated on Laurasia, and provide new insights into when, where, and how snakes originated.
The evolution of helodermatid squamatesc with description of a new taxon and an overview of Varanoidea
The Importance of Fossils in Phylogeny Reconstruction
TLDR
It is widely believed that fossils are of fundamental importance in reconstructing phylogeny and "fossils provide the soundest basis for evolutionary classification", but it is often noted that conclusions are necessarily tenuous in their absence.
