Abstract The record of fossil mammals from the Shungura Formation, lower Omo Valley southern Ethiopia, represents one largest and most carefully controlled samples for deciphering responses land faunas to global-scale climatic change. We use abundant continuous family Bovidae analyze effects a late Pliocene shift toward increased aridity in Africa beginning at 2.8 Ma intensifying about 2.4 Ma. A database consisting 4233 specimen-based records collected under well-defined procedures is used...
▪ Abstract Studies of plant and animal assemblages from both the terrestrial marine fossil records reveal persistence for extensive periods geological time, sometimes millions years. Persistence does not require lack change or absence variation one occurrence assemblage to next in time. It does, however, imply that composition is bounded occurs within those bounds. The principal cause these patterns appears be species-, perhaps clade-level, environmental fidelity results long-term tracking...

Percussive technology continues to play an increasingly important role in understanding the evolution of tool use. Comparing archaeological record with extractive foraging behaviors nonhuman primates has focused on percussive implements as a key investigating origins lithic technology. Despite this, approaches towards tools have been obscured by lack standardized methodologies. Central this issue use qualitative, non-diagnostic techniques identify from contexts. Here we describe new...
Large mammals are at high risk of extinction globally. To understand the consequences their demise for community assembly, we tracked structure through end-Pleistocene megafaunal in North America. We decomposed effects biotic and abiotic factors by analyzing co-occurrence within mutual ranges species pairs. Although shifting climate drove an increase niche overlap, decreased, signaling shifts interactions. Furthermore, effect on remained constant over time while decreased. Biotic apparently...
Significance Reconstructing the dietary adaptations of our earliest ancestors is critical to understanding evolution relationship with environment. Here, we present carbon isotope data from hominins Shungura and Usno Formations, both part Pliocene Pleistocene Omo Group, Ethiopia, a key sequence for study hominin in eastern Africa. Our show that about 2.37 Ma diet robust gracile shifted profoundly toward consumption C 4 -derived foods (largely grasses sedges), within temporal range an early...
Significance Studying the diet of fossil herbivores is a critical aspect understanding past ecology. Here, we present carbon isotope data from collective herbivore fauna in Shungura Formation, Ethiopia, key sequence for study mammalian evolution eastern Africa. We document temporal patterns nine families late Pliocene and early Pleistocene. The has significantly changed last 3.5 Ma, major dietary transitions are observed several taxa around ∼2.7 Ma then at ∼2.0 Ma. These reflect response to...
