IUCN Red List of Threatened Species

These data enabled us to infer a tree much like those derived from previous morphological analyses, but with better support for some key clades. There are also several novel elements, some of which pose striking departures from traditional ideas about lizard evolution e.

Carnivorous lizards especially snakes, mosasaurs and varanoids have proven a close second. Genetic data, presumably less burdened by the potential for adaptive convergence related to fossoriality, were expected to bipws these conflicts.

Although recent gene phylogenies seem to do so, they also differ radically from any phylogeny based on the phenotype, especially for the most ancient crown squamate divergences that occurred during the latter half of the Mesozoic.

Our study relied on traditionally prepared specimens as well as high-resolution computed tomography scans that afforded unprecedented access to the cranial anatomy of Squamata.

This, along with the inclusion of stem fossils, provided an unparalleled sample of the phenotype enabling us to more fully explore the extreme incongruences between molecular and morphological topologies for the squamate tree of life.

Despite this extensive new database, we were unable to find morphological support for the major rearrangement of bbipes deep divergences in Squamata proposed by recent molecular studies.
