The largest extant snakes live in the tropics of South America and southeast Asia where high temperatures facilitate the evolution of large body sizes among air-breathing animals whose body temperatures are dependant on ambient environmental temperatures (poikilothermy). Very little is known about ancient tropical terrestrial ecosystems, limiting our understanding of the evolution of giant snakes and their relationship to climate in the past. Here we describe a boid snake from the oldest known… 
Climate change: Snakes tell a torrid tale
TLDR
The discovery in Colombia of a giant species of fossil snake suggests that tropical climate in the past was not buffered from global warming, calling into question the idea that the climate system has a 'thermostat' that regulates tropical temperatures.
Exquisitely Preserved Fossil Snakes of Messel: Insight into the Evolution, Biogeography, Habitat Preferences and Sensory Ecology of Early Boas
Our knowledge of early evolution of snakes is improving, but all that we can infer about the evolution of modern clades of snakes such as boas (Booidea) is still based on isolated bones. Here, we
An Overview of the South American Fossil Squamates
The evolution of squamates in South America is the result of the complex geological and paleoclimatic history of this part of the world. The incomplete and episodic fossil record allows us to know
Evolution and dispersal of snakes across the Cretaceous-Paleogene mass extinction
TLDR
An extensive molecular dataset is combined with phylogenetically and stratigraphically constrained fossil calibrations to infer an evolutionary timescale for Serpentes, revealing a potential diversification among crown snakes associated with the K-Pg mass extinction.
A Late Eocene Snake Fauna from the Fayum Depression, Egypt
ABSTRACT The Eocene was a time of high ophidian diversity across much of the world, dominated by booid-grade snakes. A series of extinction events during and at the end of the Eocene resulted in a
High morphological disparity in a bizarre Paleocene fauna of predatory freshwater reptiles

TLDR
The skulls and skeletons of two new choristoderes from a single Paleocene ecosystem in western North America are described that reveal the hidden Cenozoic diversity of this reptile clade and strengthen the evidence for the existence of distinctive freshwater faunas in Paleogene Eurasia and North America.
Early giant reveals faster evolution of large body size in ichthyosaurs than in cetaceans
TLDR
The integration of fossil and extant data can improve understanding of aquatic adaptation and gigantism as patterns of convergent evolution, particularly when interpreted in an ecological context.
Biased reptilian palaeothermometer?
TLDR
It is shown that Varanus (Megalania) prisca, a large extinct lizard that lived in eastern Australia during the Late Pleistocene, was 3–4 times longer than predicted by the largest lizard species in the tropics today, which suggests that the scarcity of large predatory reptiles today may primarily be a function of competition with mammalian carnivores, rather than afunction of modern temperatures.

Skull of the large non-macrostomatan snake Yurlunggur from the Australian Oligo-Miocene
TLDR
Two exceptionally preserved skulls from the late Oligocene and early Miocene of northern Australia provide new evidence linking Yurlunggur with Wonambi and other madtsoiids, falsifying predictions of the macrostomatan hypothesis, and supporting the exclusion of Madt soiidae from the clade including all extant snakes.

TLDR
It is indicated that evidence of neotropical rainforest is exceedingly rare and equivocal before the Palaeocene, and a mismatch of evidence regarding the age of origin between sites of palaeobotanical high diversity and sites of predicted tropical climates should be reconciled with intensified collecting efforts in South America.
Stable warm tropical climate through the Eocene Epoch
Earth's climate cooled from a period of extreme warmth in the early Eocene Epoch (ca. 50 Ma) to the early Oligocene (ca. 33 Ma), when a large ice cap first appeared on Antarctica. Evidence from the

The influence of sex and body size on food habits of a giant tropical snake, Python reticulatus
TLDR
Females shifted from rats to larger mammals at a smaller body size than did conspecific males, and feeding frequencies increased more rapidly with body size in females than in males, enhancing the degree of sex difference in trophic ecology induced by sexual size dimorphism.
