Evolution, systematics, and phylogeography of pleistocene horses in the new world: a molecular perspective. [PDF]
PLoS Biology, 2005 The rich fossil record of horses has made them a classic example of evolutionary processes. However, while the overall picture of equid evolution is well known, the details are surprisingly poorly understood, especially for the later Pliocene and ...

Ancient feeding ecology inferred from stable isotopic evidence from fossil horses in South America over the past 3 Ma [PDF]
BMC Ecology, 2011 Background Stable isotope ratios (13C/12C and 18O/16O) in fossil teeth and bone provide key archives for understanding the ecology of extinct horses during the Plio-Pleistocene in South America; however, what happened in areas of sympatry between Equus ...

Climate-driven ecological stability as a globally shared cause of Late Quaternary megafaunal extinctions: the Plaids and Stripes Hypothesis. [PDF]
Biol Rev Camb Philos Soc, 2019 ABSTRACT Controversy persists about why so many large‐bodied mammal species went extinct around the end of the last ice age. Resolving this is important for understanding extinction processes in general, for assessing the ecological roles of humans, and for conserving remaining megafaunal species, many of which are endangered today.
