Soft-Tissue, Rare Earth Element, and Molecular Analyses of Dreadnoughtus schrani, an Exceptionally Complete Titanosaur from Argentina

open access: yesBiology, 2022
Evidence that organic material preserves in deep time (>1 Ma) has been reported using a wide variety of analytical techniques. However, the comprehensive geochemical data that could aid in building robust hypotheses for how soft-tissues persist over ...

Morphological study of the supratrochlear foramen in Canis lupus ssp. [PDF]

open access: yesJ Anat
The supratrochlear foramen (STF) is a common anatomical feature in the humeri of dogs and wolves. This study shows that the STF exhibits a consistent shape and position in dogs and wolves, suggesting a common morphological pattern; however, it was less frequent in smaller dog humeri, and its size correlated with humeral dimensions, suggesting that ...

Taphonomy of a clypeasteroid echinoid using a new quasimetric approach [PDF]

open access: yesActa Palaeontologica Polonica, 2016
A new quasimetric approach is used to statistically analyze taphonomic data from a commonly occurring shallow water clypeasteroid echinoid in order to obtain metric equivalent measurements of taphonomic alteration on an interval-like scale.

An osteohistological analysis of Triceratops (Ornithischia: Ceratopsidae) cranial ornamentation

open access: yesThe Anatomical Record, EarlyView.
Abstract Ceratopsids are among the most distinctive and well known extinct Cretaceous vertebrates, yet many details regarding the growth and composition of their cranial features are still not fully anatomically described or understood. In particular, striking cranial adornments such as the postorbital horns and parietal‐squamosal frill of Triceratops ...

What is taphonomy and What is not? [PDF]

open access: yesHistorical Biology, 2018
Efremov’s original definition (1940, p. 85) – ‘the study of the transition (in all its details) of animal remains from the biosphere into the lithosphere’ – set the boundaries of Taphonomy at natur...

Working with laws, regularities and singularities in biology: The evolution of mammalian red blood cell size as a case study

open access: yesThe Anatomical Record, EarlyView.
Abstract Phylogenetic comparative methods have been used in recent literature to work with laws and test for regularities (evolutionary associations of quantitative features) and evolutionary singularities (features that evolved in a single taxon). We analyzed these uses epistemologically, taking the evolution of red‐blood‐cell mean corpuscular volume (
