DNA from excrements can be amplified by means of the polymerase chain reaction. [] Key Result A chemical agent, N-phenacylthiazolium bromide, that cleaves such cross-links made it possible to amplify DNA sequences. Analyses of these DNA sequences showed that the coprolite is derived from an extinct sloth, presumably the Shasta ground sloth Nothrotheriops shastensis. Plant DNA sequences from seven groups of plants were identified in the coprolite. The plant assemblage that formed part of the sloth's diet…

A molecular analysis of ground sloth diet through the last glaciation

Thirteen families or orders of plants that formed part of the diet of the Shasta ground sloths could be identified, showing that the ground sloth was feeding on trees as well as herbs and grasses.

Nuclear Gene Sequences from a Late Pleistocene Sloth Coprolite

First coprolite evidence for the diet of Anomalopteryx didiformis, an extinct forest ratite from New Zealand

Pollen results, together with identified fragments of leaf cuticles from the coprolites, support the hypothesis that Anomalopteryx didiformis browsed trees and shrubs in the forest understorey.

Lipid analysis of a ground sloth coprolite

Coprolites, Paleogenomics and Bone Content Analysis

Coprolites are fossil scats and provide indirect witness of the activity of past animals of a given area, whether or not fossil bones of these animals are present in the site. The shape, size,

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

An integrative analysis of dog coprolites is presented, combining macroscopic analyses, stable isotope measurements, and DNA shotgun sequencing to examine diet and health status, finding that the Late Woodland dogs consumed a variety of fish as well as bird and plant taxa, possibly including maize, and also harbored intestinal parasites and pathogenic bacteria.

Metagenomic analysis of coprolites from three Late Pleistocene megaherbivores from the Southwestern United States

Background Determining the life-history traits of extinct species is often difficult from skeletal remains alone, limiting the accuracy of studies modeling past ecosystems. However, the analysis of

Molecular phylogeny of the extinct ground sloth Mylodon darwinii.

Phylogenetic analyses using homologous sequences from all extant edentate groups suggest that Mylodon darwinii was more closely related to the two- toed than the three-toed sloths and, thus, that an arboreal life-style has evolved at least twice among sloths.

The polymerase chain reaction can be used to amplify and study short mitochondrial DNA sequences that are of anthropological and evolutionary significance and opens up the prospect of performing diachronical studies of molecular evolutionary genetics.

The retrieval of ancient human DNA sequences.

These results show that more experimental work than is often applied is necessary to ensure that DNA sequences amplified from ancient human remains are authentic and quantitation of the numbers of amplifiable molecules is a useful tool to determine the role of contaminating contemporary molecules and PCR errors in amplifications from ancient DNA.

Death of American Ground Sloths

Dates from other caves in the arid Southwest indicate that the Shasta ground sloth disappeared at very soon after the time of Clovis big game hunters, in accord with the model of explosive overkill.
