A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

open access: yesThe Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

THE PERSPECTIVES OF PALEOGENETICS IN ALBANIA: INSIGHTS FROM FOSSIL AND SEDIMENTARY DNA

open access: yesAlbanian Journal of Natural and Technical Sciences
Paleontology, sedimentology, and DNA are closely connected through a common objective: to understand, as comprehensively as possible, the evolution of life on Earth. Paleontology, the science that studies fossils, directly provides morphological evidence

PALEONTOLOGY AND EVOLUTIONARY THEORY [PDF]

open access: yesEvolution, 1974
In the introduction to the recently published collection Models in Paleobiology, Schopf (1972, p. 4) says, "We look with awe at the results which have followed the application of fundamental chemistry in a geochemical context, and the use of cartesian methodology in molecular biology.

Previously undocumented regional variability in crab‐eating macaque skull sexual dimorphism and its implications for biological and morphometric studies

open access: yesThe Anatomical Record, EarlyView.
Abstract In a large sample of adult crab‐eating macaques, we quantified sexual dimorphism in size, shape, and covariance across the whole skull and among anatomical regions of the cranium and mandible. All regions showed significant mean sex differences, but the magnitude of size and shape dimorphism varied substantially.

Laser-stimulated fluorescence in paleontology. [PDF]

open access: yesPLoS ONE, 2015
Fluorescence using ultraviolet (UV) light has seen increased use as a tool in paleontology over the last decade. Laser-stimulated fluorescence (LSF) is a next generation technique that is emerging as a way to fluoresce paleontological specimens that ...
