Decay stages of Jurassic wood debris from Scotland: evidence for the coevolution of fungal rot, arthropods and the nurse log strategy. [PDF]

New Phytol
Summary A key feature of extant conifer forests is the high percentage of seeds that germinate and establish on dead wood; in some forests, this can exceed 90%. This deadwood can act as an ideal nursery for young tree species, leading to this type of seedbed being termed ‘nurse logs’.

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

Integrative analysis of DNA, macroscopic remains and stable isotopes of dog coprolites to reconstruct community diet

Scientific Reports, 2021
Paleofeces or coprolites are often used to reconstruct diet at archaeological sites, usually using macroscopic analyses or targeted DNA amplification and sequencing.

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.

Syphacia sp. (Nematoda: Oxyuridae) in coprolites of Kerodon rupestris Wied, 1820 (Rodentia: Caviidae) from 5,300 years BP in northeastern Brazil

Memorias do Instituto Oswaldo Cruz, 2012
We present the results of paleoparasitological analyses in coprolites of Kerodon rupestris, rodent endemic to rocky areas of Brazil's semiarid region. The coprolites were collected from excavations at the archaeological site of Toca dos Coqueiros, in the
