No Evidence for Clovis Comet Catastrophe, Archaeologists Say
ScienceDaily (Sep. 29, 2010)

New research challenges the controversial theory that an ancient comet impact devastated the Clovis people, one of the earliest known cultures to inhabit North America

Writing in the October issue of Current Anthropology, archaeologists Vance Holliday (University of Arizona) and David Meltzer (Southern Methodist University) argue that there is nothing in the archaeological record to suggest an abrupt collapse of Clovis populations. "Whether or not the proposed extraterrestrial impact occurred is a matter for empirical testing in the geological record," the researchers write. "Insofar as concerns the archaeological record, an extraterrestrial impact is an unnecessary solution for an archaeological problem that does not exist."

The comet theory first emerged in 2007 when a team of scientists announced evidence of a large extraterrestrial impact that occurred about 12,900 years ago. The impact was said to have caused a sudden cooling of the North American climate, killing off mammoths and other megafauna. It could also explain the apparent disappearance of the Clovis people, whose characteristic spear points vanish from the archaeological record shortly after the supposed impact.

As evidence for the rapid Clovis depopulation, comet theorists point out that very few Clovis archaeological sites show evidence of human occupation after the Clovis. At the few sites that do, Clovis and post-Clovis artifacts are separated by archaeologically sterile layers of sediments, indicating a time gap between the civilizations. In fact, comet theorists argue, there seems to be a dead zone in the human archaeological record in North America beginning with the comet impact and lasting about 500 years.

But Holliday and Meltzer dispute those claims. They argue that a lack of later human occupation at Clovis sites is no reason to assume a population collapse. "Single-occupation Paleoindian sites -- Clovis or post-Clovis -- are the norm," Holliday said. That's because many Paleoindian sites are hunting kill sites, and it would be highly unlikely for kills to be made repeatedly in the exact same spot.

"So there is nothing surprising about a Clovis occupation with no other Paleoindian zone above it, and it is no reason to infer a disaster," Holliday said.

In addition, Holliday and Meltzer compiled radiocarbon dates of 44 archaeological sites from across the U.S. and found no evidence of a post-comet gap. "Chronological gaps appear in the sequence only if one ignores standard deviations (a statistically inappropriate procedure), and doing so creates gaps not just around [12,900 years ago] but also at many later points in time," they write.

Sterile layers separating occupation zones at some sites are easily explained by shifting settlement patterns and local geological processes, the researchers say. The separation should not be taken as evidence of an actual time gap between Clovis and post-Clovis cultures.

Holliday and Meltzer believe that the disappearance of Clovis spear points is more likely the result of a cultural choice rather than a population collapse. "There is no compelling data to indicate that North American Paleoindians had to cope with or were affected by a catastrophe, extraterrestrial or otherwise, in the terminal Pleistocene," they conclude.

P.S. It's not 12.500 bc, but 12.900 years ago, but that wouldn't fit the title :mrgreen: anywayz, it's a curious timeframe 12.500 years ago is where all the scientists go vague with their facts! but people in the fringe sciense like Graham Hancock & many many others go crazy on this period.! Something strange happened back then, thats for sure...

Reason why it was a comet.
1. Great Lakes Event, which immediately affected the easter half of North America and Western Europe.
2. Flash frozen remains of mammoths found in eastern regions of North East Canada and New Foundland glaciers carbon date to this event.
3. Plant life found in the stoches and moths of said mammoths.
4. The dolumstone cap shows imo the impact site, it is round it is the reason why the niagara escarpment exists. The impact disrupted the already existing salt water ice locked body known as Iraquois Lake.
5. The impact would have destroyed an ice dam which would have been located at Indian Creek Valley in the St. Lawrance Valley.
6. The impact would have also caused tectonic activity along the rift between lakes Superior and Ontario, the rift being the reason for the great depths of both lakes.
7. Clovis points found in France continued after event in Eastern North America while Clovis points seesed to exist in North East America at around 12,500 years imo (13,000 )years ago.
8. The region around the theoretical impact crater would with in 1,600 years become the highest population density of Native American Tribes in North America. Ex. The Iraquois Nation, whos' emergance is debated at around 8,000 to 10,000 years ago.
9. The discovery of micro meteorites in and around the region of the (impact )dolumstone cap is imo a dead give away.
10. Salt mines, and artifacts of clovis people lie below the dolumstone cap, micro-meteorrites, and shale strata lies above for approximately 500 to 1,600 years before the emergance of civilizations return.
The arguement of the said two archaeologists, is weak. Then again this is a study based on one form of science. Simple geology shows us that what ever happend was very sudden and of major proportions, and this is when i suggest the Great Flood and the final destruction of Atlantis occured. It was a sigle event domino effect resulting in a culmination of many insurmountable events. Of course some of this is my oppinion, however it fits well. Thanks for the thought provolking post Kingz. :D

What he said. There is significant evidence of some kind of impact event followed by what was most likely global deluge. Large portions of the area inhabited by the Clovis people would most likely have been under water for a long time afterward as well. It is easy to lie or manipulate with statistics and conventional archaeology would be all up on that because conventional archaeology does not want to talk about the possibility of a global catastrophe wiping out what was probably a civilization more advanced than they admit as well.

Thanks for the post Kingz. I kinda want to read their paper now.
