TL;DR: In the case of early (ca. 12,000-10,000 B.P.) Paleoindian groups in the Americas, the availability of neighboring groups with a detailed knowledge of local resource geography could not be relied upon as discussed by the authors.

TL;DR: A late Oligocene fossil assemblage from Ethiopia is reported, which constrains the migration to postdate 27 Myr ago, and yields new insight into the indigenous faunal dynamics that preceded this event.

TL;DR: The Hudson-Meng bone bed in northwestern Nebraska is an early Holocene deposit of hundreds of bison of diVering ages that were killed in a catastrophic event of unknown origin, and the M 1,M 2, and M 3 molars of individuals were examined to determine inter-and intra-tooth isotopic variability, and to link this variability to time in order to better understand the environments that existed prior to the mass death event.

TL;DR: It is proposed, on the basis of close study of her skeleton, that Lucy's cause of death was a vertical deceleration event or impact following a fall from considerable height that produced compressive and hinge (greenstick) fractures in multiple skeletal elements.

TL;DR: The Folsom Paleoindian type site has been extensively studied in the last few decades as discussed by the authors, and all of the excavations to date have been in the kill area, which took place in a small and relatively shallow tributary to the Pleistocene paleovalley of Wild Horse Arroyo.
