The earliest evidence for Upper Paleolithic occupation in the Armenian Highlands at Aghitu-3 Cave.
With its well-preserved archaeological and environmental records, Aghitu-3 Cave permits us to examine the settlement patterns of the Upper Paleolithic (UP) people who inhabited the Armenian Highlands. We also test whether settlement of the region between ∼39-24,000 cal BP relates to environmental variability. The earliest evidence occurs in archaeological horizon (AH) VII from ∼39-36,000 cal BP...
متن کاملResponse to comment on "Bilaterian burrows and grazing behavior at >585 million years ago".
Gaucher et al. suggest that their field observations and petrographic analysis of one thin section do not support an Ediacaran age for the trace fossils-bearing strata of the Tacuarí Formation. We have strengthened our conclusion of an Ediacaran age for the Tacuarí Formation based on reassessment of new and previously presented field and petrographic evidence.
متن کاملComment on "Bilaterian burrows and grazing behavior at >585 million years ago".
Pecoits et al. (Reports, 29 June 2012, p. 1693) describe bilaterian trace fossils and assign them an Ediacaran age based on the age of a granite interpreted as intrusive. We argue that the granite is not intrusive but in fact represents the basement of the sedimentary succession. Moreover, we show that identical trace fossils occur in nearby Carboniferous-Permian glacigenic rocks.
متن کاملTesting a Blowing Snow Model Against Distributed Snow Measurements at Upper Sheep Creek, Idaho, USA
In this paper a physically-based snow transport model (SnowTran-3D) was used to simulate snow drifting over a 30 m grid, and was compared to detailed snow water equivalence (SWE) surveys on three dates within a small 0.25 km 2 subwatershed, Upper Sheep Creek. Two precipitation scenarios and two vegetation scenarios were used to carry out four snow transport model runs in order to: (1) evaluate ...
متن کاملThe Upper Paleolithic Revolution
■ Abstract The transition from the Middle Paleolithic to the Upper Paleolithic is considered one of the major revolutions in the prehistory of humankind. Explanations of the observable archaeological phenomena in Eurasia, or the lack of such evidence in other regions, include biological arguments (the role of Cro-Magnons and the demise of the Neanderthals), as well as cultural-technological, an...
