Microbial communities in pre-columbian coprolites. [PDF]

PLoS ONE, 2013
The study of coprolites from earlier cultures represents a great opportunity to study an "unaltered" composition of the intestinal microbiota. To test this, pre-Columbian coprolites from two cultures, the Huecoid and Saladoid, were evaluated for the ...

Determining whether a phosphatic concretion containing a Cretaceous juvenile crocodylian is a coprolite or a non-fecal concretion [PDF]

Scientific Reports
Phosphatic concretions in terrestrial settings are often identified as coprolites based upon their biotic contents and high phosphorus levels. However, recent discoveries have shown that non-fecal origins of fossiliferous phosphatic concretions are more ...

Mineralization Controls Informative Biomarker Preservation Associated With Soft Part Fossilization in Deep Time. [PDF]

Geobiology
ABSTRACT Diagenetically mineralized fossil tissues represent invaluable paleobiological evidence of past life. Lipid biomarkers may be identified alongside fossils, yet the relationship between localized, diagenetic mineral precipitation, and lipid preservation remains underexplored.

Validating a Target-Enrichment Design for Capturing Uniparental Haplotypes in Ancient Domesticated Animals. [PDF]

Mol Ecol Resour
ABSTRACT In the last three decades, DNA sequencing of ancient animal osteological assemblages has become an important tool complementing standard archaeozoological approaches to reconstruct the history of animal domestication. However, osteological assemblages of key archaeological contexts are not always available or do not necessarily preserve enough

X-ray tomographic microscopy of Eocene coprolites from Pipestone Springs Main Pocket, southwest Montana

Frontiers in Earth Science, 2023
The Eocene Pipestone Springs Main Pocket (Renova Formation, Jefferson County, Montana, United States of America) is a locality renowned for its diverse Chadronian (late Eocene; ∼38–33.9 million years ago) mammalian fauna and abundant coprolites.

Sequential biomolecular, macrofossil, and microfossil extraction from coprolites for reconstructing past behavior and environments

Frontiers in Ecology and Evolution, 2023
The study of macroscopic, microscopic, and biomolecular remains recovered from coprolites can provide a wide range of information on past human and animal behavior and environments.

The Technological Advance and Application of Coprolite Analysis

Frontiers in Ecology and Evolution, 2022
Coprolites (mummified or fossilized feces), belonging to the group of ichnofossils, are fossilized remains of feces produced by animals. Various types of data from coprolites provide detailed evidence of the producer’s condition, like diet, intestinal ...

Gut Microbiome of an 11th Century A.D. Pre-Columbian Andean Mummy [PDF]

, 2015
The process of natural mummification is a rare and unique process from which little is known about the resulting microbial community structure. In the present study, we characterized the microbiome of paleofeces, and ascending, transverse and descending ...

Different Human–Dog Interactions in Early Agricultural Societies of China, Revealed by Coprolite

Frontiers in Earth Science, 2021
Dogs served in a variety of capacities in prehistory. After their domestication in Paleolithic hunter-gatherer societies, the emergence of agriculture shifted their partnerships with people.

High-resolution coproecology: Using coprolites to reconstruct the habits and habitats of New Zealand’s extinct upland Moa (Megalapteryx didinus) [PDF]

, 2005
Knowledge about the diet and ecology of extinct herbivores has important implications for understanding the evolution of plant defence structures, establishing the influences of herbivory on past plant community structure and composition, and identifying
