Titlebook: Hominin Environments in the East African Pliocene; An Assessment of the René Bobe,Zeresenay Alemseged,Anna K. Behrensmeyer Book 2007 Spring

客观

Environmental hypotheses of Pliocene human evolution,n adaptations (and lineages) should have corresponded with heightened environmental variability, while new adaptations evolved during those periods should have enabled a lineage to persist (and spread) through a novel range of habitats. Turnover hypotheses, on the other hand, concern the timing and

COKE

African Pliocene and Pleistocene cercopithecid evolution and global climatic change,a are examined for the Afar Depression and Turkana Basin, whereas only the species range data are studied for all East African and complete sub-Saharan analyses. The results provide no support for a turnover pulse 2.8–2.5 Ma. In fact, the largest number of first and last appearances are clustered ar

Comparability of fossil data and its significance for the interpretation of hominin environments,the middle of Member G (G-13) is observed in both samples and is caused by the important change in the depositional environment from fluvial to lacustrine conditions. (2) The French team collected more specimens than the American team, in part because it had a larger area of exposures, and it spent

The effects of collection strategy and effort on faunal recovery, that are less well documented, likely related to differences in research strategies and the inherent richness of the sediments explored. And finally, it suggests how the collections might be best used to avoid the effects of biases that they apparently contain.

Taphonomy and paleoecological context of the Upper Laetolil Beds (Localities 8 and 9), Laetoli in nose previously described. Fossil faunal remains from the Upper Laetolil Beds are represented by highly variable numbers of skeletal parts dominated by heavily fractured and/or modified distal, proximal, and midshaft fragments of varying sizes, and many isolated teeth. Unlike marine fossil deposits,

The paleoecology of the Upper Laetolil Beds at Laetoli,paper is to re-examine this issue by more thoroughly documenting the paleoecological setting by conducting a more detailed and comprehensive comparative analysis of the mammalian fauna. To this end, the ecovariable structure of the mammalian fauna at Laetoli is compared to other Plio-Pleistocene hom
