Megaherbivore coprolite DNA: yields and comparison of three ancient DNA extraction protocols on coprolites of giant ground sloth Mylodon darwinii [PDF]

PeerJ
Coprolites offer rich potential for palaeodietary studies as snapshots of past dietary behaviour and environment. They require adapted laboratory methods to retrieve the DNA of the depositor, its microbiome, diet and environmental taxa.

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 ...

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.

Viruses in a 14th-Century Coprolite [PDF]

Applied and Environmental Microbiology, 2014
ABSTRACT Coprolites are fossilized fecal material that can reveal information about ancient intestinal and environmental microbiota. Viral metagenomics has allowed systematic characterization of viral diversity in environmental and human-associated specimens, but little is known about the viral diversity in fossil remains.

Polyphasic analysis of a middle ages coprolite microbiota, Belgium.

PLoS ONE, 2014
Paleomicrobiological investigations of a 14(th)-century coprolite found inside a barrel in Namur, Belgium were done using microscopy, a culture-dependent approach and metagenomics. Results were confirmed by ad hoc PCR--sequencing.

The steroids of 2000-year-old human coprolites

Journal of Lipid Research, 1978
Six samples of human coprolites, some more than 2,000 years old, were analyzed for fecal steroid composition. Despite this very lengthy period of storage, the fecal steroids of coprolites were remarkably similar to those of stool samples collected today.

Discovery of a 240 million year old nematode parasite egg in a cynodont coprolite sheds light on the early origin of pinworms in vertebrates

Parasites & Vectors, 2014
Background We report the discovery of a nematode parasite egg (Nemata: Oxyurida) from a coprolite closely associated with the remains of several species of Cynodontia, dated to 240 million years old.
