Tooth histotype and enameloid microstructure of Priohybodus arambourgi d'Erasmo, 1960 (Elasmobranchii: Hybodontiformes) from the Late Jurassic of northeastern Brazil

The Anatomical Record, EarlyView.
Abstract Sharks possess varied diets and different prey capture mechanisms. As a result, the group exhibits a significant diversity in dental morphology, also reflecting the internal structures of the teeth. Internal dental anatomy points to the existence of three histotypes in elasmobranch phylogeny: orthodont, osteodont, and pseudoosteodont ...

Functional diversity of microbial ecologies estimated from ancient human coprolites and dental calculus

Philosophical Transactions of the Royal Society of London. Biological Sciences, 2020
Human microbiome studies are increasingly incorporating macroecological approaches, such as community assembly, network analysis and functional redundancy to more fully characterize the microbiome.

Neolithic Human Diet Based on Studies of Coprolites from the Swifterbant Culture Sites, the Netherlands: Synthesis - Human versus community diet

, 2022
The aim of this final chapter is to integrate the results obtained from the multi-disciplinary study applied to a series of coprolites from the Late Mesolithic and Early Neolithic Swifterbant Culture sites, to determine their role as a source of ...

Integrating ZooMS and taphonomy further highlights differential processing of animal and Neandertal carcasses in the Quina Mousterian at Les Pradelles (Marillac‐le‐Franc, southwest France)

Journal of Quaternary Science, EarlyView.
ABSTRACT The cave of Les Pradelles (Marillac‐le‐Franc, France) was repeatedly visited by Neandertals ~55 000 years ago and is a key site in discussions of Neandertal cannibalism. Excavations between 1967 and 1980 (Vandermeersch) and between 2001 and 2013 (Maureille/Mann) produced a rich faunal assemblage (>20 000 bones), alongside Quina Mousterian ...

Helminth Parasites of Coprolites [PDF]

, 1987
Parasites from Bighorn Sheep Cave coprolites were examined for the presence of parasites using standard methods. Both Toxascaris and Enterobius were identified from coprolites recovered from the cave.

Neolithic Human Diet Based on Studies of Coprolites from the Swifterbant Culture Sites, the Netherlands: Micro-CT scanning analysis

, 2022
In recent years, several researchers have illustrated the potential of X-ray micro-computed tomography (micro-CT) in the study of archaeological soils and artefacts. Hunt et al., Huisman et al., Wang et al., Qvarnström et al., and Shillito et al.

Let's Talk About Bone Cylinders. Taphonomy of Carnivores and Humans

International Journal of Osteoarchaeology, EarlyView.
ABSTRACTBone cylinders are a distinctive structure predominantly produced by durophagous carnivoran species during the consumption of long bones, in which the diaphyseal canal remains intact while both epiphyses are removed or consumed. This study evaluates the significance of this morphology, traditionally attributed to extant and extinct hyena ...

The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

Integrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

COMPARISON OF FIVE DIFFERENT DNA EXTRACTION METHODS FOR MICROBIOME RECONSTRUCTION FROM COPROLITES [PDF]

, 2017
The human microbiome has become an intense area of research over the past fifteen years due to its importance for understanding human health and disease. The revolution in Next-Generation Sequencing (NGS) techniques has made microbiome science accessible
