Dung of Mammuthus in the arid Southwest, North America
TLDR
The discovery of a unique organic deposit in a dry cave on the Colorado Plateau, southern Utah, permits the first comparison of the physical characteristics and the diet of the extinct mammoths of the arid Southwest, North America, with that of mammoths from Siberia and northern China, the only other known locations of such remains as mentioned in this paper.About:

Sporormiella fungal spores, a palynological means of detecting herbivore density
Owen K. Davis,David S. Shafer +1 more
TL;DR: Spores of the dung fungus Sporormiella are abundant in lake and cave sediment where livestock are plentiful in the western United States during the historic period as mentioned in this paper, reaching values of 2-4% in Pleistocene samples from lake sediments.
Journal ArticleDOI
Mammalian extinctions in the late Pleistocene of northern Eurasia and North America.
TL;DR: Although a global phenomenon, late Pleistocene extinctions were most severe in North America, South America and Australia, and moderate in northern Eurasia (Europe plus Soviet Asia), in Africa, where nearly all of the late Pleistsocene ‘megafauna’ survives to the present day, losses were slight.
Journal ArticleDOI
The preservation of glacial-interglacial climatic signatures in the oxygen isotopes of elephant skeletal phosphate
TL;DR: In this article, the same authors found that enamel, dentine, cementum and bone of modern elephant bone and teeth vary linearly according to the δ18O of local meteoric water, a parameter with close ties to regional and local climatic conditions.
Journal ArticleDOI
Spores of the Dung Fungus Sporormiella: Increased Abundance in Historic Sediments and Before Pleistocene Megafaunal Extinction
TL;DR: Spores of the dung fungus Sporormiella become abundant following the historic introduction of grazing herbivores at seven sites in the western United States during the Holocene as mentioned in this paper.
Journal ArticleDOI
Late Pleistocene C4Plant Dominance and Summer Rainfall in the Southwestern United States from Isotopic Study of Herbivore Teeth
TL;DR: In this article, the isotope data indicate that interactions of seasonal moisture, temperature, and lowered atmospheric pCO2determined glacial-age C4abundance patterns.

Rampart Cave Coprolite and Ecology of the Shasta Ground Sloth
TL;DR: The shasta ground sloth Nothrotherium shastense inhabited Rampart Cave in the Grand Canyon of the Colorado River, Arizona, for at least 25,000 years as mentioned in this paper.

Shasta ground sloth ( Nothrotheriops shastense hoffstetter) at Shelter Cave, New Mexico: Environment, diet, and extinction
TL;DR: In this paper, seven coprolites of the extinct Shasta ground sloth (Nothrotheriops shastense) were recently discovered in the Los Angeles County Museum collection from Shelter Cave, New Mexico.

Late quaternary plant zonation and climate in southeastern utah
TL;DR: In this paper, plant macrofossils from packrat middens in two southeastern Utah caves outline development of modern plant zonation from the late Wisconsin, and show that Engelmann spruce-alpine fir forest was replaced by the present vegetation consisting of pinyon-juniper woodland on exposed ridgetops and cliffside stands of Douglas fir, ponderosa pine, and aspen.
