Modern snakes originated from burrowing ancestors, predicted from the evolution of their inner ear. Modern snakes probably originated as habitat specialists, but it controversial unclear whether they were ancestrally terrestrial burrowers or marine swimmers. We used x-ray virtual models of the inner ear to predict the habit of Dinilysia patagonica, a stem snake closely related to the origin of modern snakes. Previous work has shown that modern snakes perceive substrate vibrations via their… 

The ecological origins of snakes as revealed by skull evolution

An integrative geometric morphometric approach is used that suggests evolution from terrestrial to fossorial in the most recent common ancestor of extant snakes, and indicates that snakes later evolved novel craniofacial specializations through global acceleration of skull development.

The morphology of the inner ear of squamate reptiles and its bearing on the origin of snakes

The inner ear morphology of Dinilysia is consistent with semi-aquatic as well as semi-Fossorial habits: the most similar forms are either semi-fossorial burrowers with a strong affinity to water (Xenopeltis and Cylindrophis) or amphibious, intertidal forms which shelter in burrows (Myron).

Palaeoecological inferences for the fossil Australian snakes Yurlunggur and Wonambi (Serpentes, Madtsoiidae)

The inner ear of Yurlunggur most closely resembles both that of certain semiaquatic snakes and that of some semifossorial snakes, and osteology, palaeoclimatic data and the palaeobiogeographic distribution of these two snakes are consistent with these inferred ecological differences.

Feeding in Snakes: Form, Function, and Evolution of the Feeding System

A wide range of research on these and other topics has shown that snakes are a rich group for studying form, function, behavior, ecology, and evolution.

First evidence of convergent lifestyle signal in reptile skull roof microanatomy

It is found that fossoriality evolved independently in 54 lepidosaur lineages and a highly compact skull roof, small skull diameter, elongate cranium, and low length ratio of frontal and parietal were repeatedly acquired in concert with a fossorial lifestyle.

Ecomorphological diversification in squamates from conserved pattern of cranial integration

It is demonstrated that highly diverse phenotypes, exemplified by lizards and snakes, can and do arise from differential selection acting on conserved patterns of phenotypic integration, and the primary drivers of their cranial evolution within a unified, quantitative framework.

Sensory Evolution and Ecology of Early Turtles Revealed by Digital Endocranial Reconstructions

3D digital reconstructions and comparative descriptions of the brain, nasal cavity, neurovascular structures and endosseous labyrinth of Proganochelys quenstedti, one of the earliest stem-turtles, as well as other turtle taxa demonstrate that an increase in size and regionalization of thebrain took place in the course of turtle evolution, achieving an endocast diversity comparable to other amniote groups.

Evolution of the sauropterygian inner ear with increasingly pelagic lifestyles

Sauropterygia, a successful clade of marine reptiles abundant in aquatic ecosystems of the Mesozoic, inhabited nearshore to pelagic habitats over >180 million years of evolutionary Aquatic



A transitional snake from the Late Cretaceous period of North America

Previously undescribed material from this ancient snake is reported, including the maxilla, dentary and additional vertebrae, suggesting that Coniophis is not an anilioid as previously thought and instead represents the most primitive known snake.

The origin of snakes: revealing the ecology, behavior, and evolutionary history of early snakes using genomics, phenomics, and the fossil record

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.

A four-legged snake from the Early Cretaceous of Gondwana

A fossil from the Brazilian Cretaceous period that contains a snakelike species that is elongate and serpentine, with both hind- and forelimbs, suggests that crown Serpentes originated in Gondwana.

The oldest known snakes from the Middle Jurassic-Lower Cretaceous provide insights on snake evolution.

Snake fossils that extend the record backwards in time by an additional ~70 million years (Middle Jurassic-Lower Cretaceous) are reported on, suggesting that snakes had undergone habitat differentiation and geographic radiation by the mid-Jurassic.

The origin of snake feeding

Evidence is presented that mosasaurs — large, extinct marine lizards related to snakes — represent a crucial intermediate stage in snake skull evolution, and intermediate morphologies inSnake skull evolution should perhaps be sought not in small burrowing lizards, as commonly assumed, but in large marine forms.

A Cretaceous terrestrial snake with robust hindlimbs and a sacrum

The new fossil from the Upper Cretaceous period of Patagonia fills an important gap in the evolutionary progression towards limblessness and retains several features associated with a subterranean or surface dwelling life that are also present in primitive extant snake lineages, supporting the hypothesis of a terrestrial rather than marine origin of snakes.

Assembling the Squamate Tree of Life: Perspectives from the Phenotype and the Fossil Record

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.

The anatomy of the upper cretaceous snake Najash rionegrina Apesteguía & Zaher, 2006, and the evolution of limblessness in snakes

Najash rionegrina documents an important gap in the evolutionary development towards limblessness, because its phylogenetic affinities suggest that it is the sister group of all modern snakes, including the limbed Tethyan snakes Pachyrhachis, Haasiophis, and Eupodophis.


The ancestors of snakes, irrespective of their habits, were closely related to the platynotid lizards, and the respective merits of these assumptions must mainly be assessed on evidence obtained from study of living forms.

The skull of the Upper Cretaceous snake Dinilysia patagonica Smith-Woodward, 1901, and its phylogenetic position revisited

Results of a phylogenetic analysis support a basal position of Dinilysia, as the sister-taxon to all extant snakes, and confirm the presence of a crista circumfenestralis, which represents an important derived ophidian synapomorphy.
