The head and neck muscles associated with feeding in sphenodon (Reptilia: Lepidosauria: Rhynchocephalia) [PDF]

open access: yes, 2009
Feeding in Sphenodon, the tuatara of New Zealand, is of interest for several rea-sons. First, the modern animal is threatened by extinction, and some populations are in competition for food with Pacific rats.

Anatomy, morphology and evolution of the patella in squamate lizards and tuatara (Sphenodon punctatus) [PDF]

open access: yes, 2016
The patella (kneecap) is the largest and best-known of the sesamoid bones, postulated to confer biomechanical advantages including increasing joint leverage and reinforcing the tendon against compression.

Evolution of the temporal skull openings in land vertebrates: A hypothetical framework on the basis of biomechanics

open access: yesThe Anatomical Record, Volume 307, Issue 4, Page 1559-1593, April 2024.
Abstract The complex constructions of land vertebrate skulls have inspired a number of functional analyses. In the present study, we provide a basic view on skull biomechanics and offer a framework for more general observations using advanced modeling approaches in the future.

VALLESAURUS CENENSIS WILD, 1991, A DREPANOSAURID (REPTILIA DIAPSIDA) FROM THE LATE TRIASSIC OF NORTHERN ITALY

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2006
Vallesaurus cenensis, a small drepanosaurid reptile from the Norian (Late Triassic) beds of the Calcare di Zorzino (Zorzino Limestone) is described. The holotype and only known specimen represents the first drepanosaurid in which the skull is preserved ...

Steric antisense inhibition of AMPA receptor Q/R editing reveals tight coupling to intronic editing sites and splicing [PDF]

open access: yes, 2012
Adenosine-to-Inosine (A-to-I) RNA editing is a post-transcriptional mechanism, evolved to diversify the transcriptome in metazoa. In addition to wide-spread editing in non-coding regions protein recoding by RNA editing allows for fine tuning of protein ...

New lizard record (Diapsida, Lepidosauria) from the Upper Cretaceous Adamantina Formation, Brazil [PDF]

open access: yesBulletin of Geosciences, 2009
A new record of a Late Cretaceous lizard-like non-serpentian squamate from Adamantina Formation (Bauru Group; Turonian-Santonian) southeast of Brazil is based on a specimen found about 10 km south of Marília city (São Paulo State). The material consists of 10 articulated dorsal vertebrae with a total length of 14 mm and seven incomplete right ribs ...

Inter-vertebral flexibility of the ostrich neck:implications for estimating sauropod neck flexibility [PDF]

open access: yes, 2013
The flexibility and posture of the neck in sauropod dinosaurs has long been contentious. Improved constraints on sauropod neck function will have major implications for what we know of their foraging strategies, ecology and overall biology.

RAIBLIANIA CALLIGARISI GEN. N., SP. N., A NEW TANYSTROPHEID (DIAPSIDA, TANYSTROPHEIDAE) FROM THE UPPER TRIASSIC (CARNIAN) OF NORTHEASTERN ITALY

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2020
Tetrapod remains are extremely rare in the early Carnian (Late Triassic) Calcare del Predil Formation on the Italian side of the Julian Alps (Friuli Venezia Giulia Autonomous Region), which yielded the Raibl fossil assemblage including the famous "Raibl ...
