Identification of fossil squamate
reptiles (lizards and snakes) is typically a challenge due to the lack of comprehensive osteological collections of extant taxa.
The outer, beta keratin-rich layer of the squamate
epidermis bears intricate fine sculpturing (microornamentation), which varies from base to apex of an individual scale.
In southern France, several squamates
have been reported in Champ-Garimond (Iguanidae indet.
Structures such as longitudinal ridges characteristic of limbless squamates
or short legs may facilitate locomotion on inclined surfaces (Smith et al.
Close-up photography and high-definition video also reveal the extraordinary world of squamates
, researchers have demonstrated a positive correlation between adult body size and age at maturation (e.
Frost has been interested in squamates
since he was a kid.
This Grey-Banded Kingsnake is just one species that's part of a group of animals called squamates
Typical n ode-based definitions, then, might read as follows: "Lepidosauria is the most recent common ancestor of Sphenodon and squamates
and all of its descendants" or "Mammalia is the most recent common ancestor of montremes and therians and all of their descendants.
It is widely assumed that there is a functional relationship in squamates
between extrusion of the tongue (tongue flick behavior) and delivery of chemical cues to the vomeronasal system (VNS).
We also assert that resolution of our debate has important implications for understanding the evolution of reproductive effort in squamates
1990) provided a preliminary list of the Lano vertebrates, including actinopterygians, lissamphibians, squamates
, turtles, crocodyliforms, dinosaurs, pterosaurs, and mammals from the continental deposits, and selachians from the marine beds.
are one of the groups of reptiles with the greatest variation in life histories.
Griggs Assistant Professor of Biology in GW's Columbian College of Arts and Sciences, along with researchers from the City University of New York and Arizona State University, detail the cataloguing of 4,161 species of snakes and lizards, or squamates
We grouped animals as amphibians, turtles, or squamates
(lizards and snakes) when constructing the accumulation curves because these groupings are typically the units of interest for study and management, rather than the more specific morphological or locomotory groupings that were necessary to use when comparing the effectiveness of different trap types.
