The Clovis complex is considered to be the oldest unequivocal evidence of humans in the Americas, dating between 11,500 and 10,900 radiocarbon years before the present (14C yr B.P.). Adjusted 14C dates and a reevaluation of the existing Clovis date record revise the Clovis time range to 11,050 to 10,800 14C yr B.P. In as few as 200 calendar years, Clovis technology originated and spread throughout North America. The revised age range for Clovis overlaps non-Clovis sites in North and South… Expand
Comment on "Redefining the Age of Clovis: Implications for the Peopling of the Americas"
Waters and Stafford (Reports, 23 February 2007, p. 1122) provided useful information about the age of some Clovis sites but have not definitively established the temporal span of this culturalExpand
PRE-CLOVIS IN THE AMERICAS: INTERNATIONAL SCIENCE CONFERENCE PROCEEDINGS

Response to Comment on "Redefining the Age of Clovis: Implications for the Peopling of the Americas"
Haynes et al. misrepresent several aspects of our study. Our revised dates and other archaeological data imply that Clovis does not represent the earliest occupation of the Americas, and we offeredExpand
Clovis: On the Edge of a New Understanding
This publication of the latest archaeological research about the Clovis big-game hunters clearly indicates a major change in current conceptions about the history of early man in the Americas.Expand
The Millennium before Clovis
Abstract This paper reviews the published information, uncertainties about claims, and possible technological and cultural relationships of a sample of sites which have older-than-Clovis dates inExpand

ABSTRACT A recent report in PaleoAmerica presented the recovery of a Clovis point from a stratified context in the western foothills of the Sierra Nevada, Tuolomne County, California. The associatedExpand
DNA from Pre-Clovis Human Coprolites in Oregon, North America
TLDR
It is established that humans were present at Paisley 5 Mile Point Caves, in south-central Oregon, by 12,300 14C years B.P, through the recovery of human mitochondrial DNA from coprolites, directly dated by accelerator mass spectrometry. Expand
The Buttermilk Creek Complex and the Origins of Clovis at the Debra L. Friedkin Site, Texas
TLDR
The Buttermilk Creek Complex confirms the emerging view that people occupied the Americas before Clovis and provides a large artifact assemblage to explore ClovIS origins. Expand

TLDR
The discovery of a Paleoindian complex in central Alaska, combined with the recent redating of the Bering Land Bridge and key archeological sites, suggests that Beringia was settled during the final Pleistocene interstadial. Expand

Changes in North Atlantic Radiocarbon Reservoir Ages During the Allerød and Younger Dryas
TLDR
Radiocarbon age difference between the shells and the plants showed that sea surface reservoir ages increased from 400 to 600 years in the early YD, stabilized for 900 years, and dropped by 300 years within a century across the YD-Holocene transition. Expand
