Archaeology of the YD boundary event

20 May 2010

At http://journalofcosmology.com/Extinction119.html ‘Archaeological Perspectives on the Extra Terrestrial Impact Hypothesis at 12900BC: A View from Western North America’ by Terry Jones – available to download in pdf format. It is surprising that so many Clovis culture objects and associated archaeology are assumed to date from the Clovis Period (the few centuries or so leading up to the YD event) and Palaeo-Indian Holocene deposits do not appear to connect with them. Human populations appear to have recovered after the YD event, some 1300 years in total, but they are not particularly visible in an archaeological sense until 10,000 years ago (nearly 3000 years after the YD boundary event). However, the Palaeo Indian presence is weak as far as C14 dates are concerned and only by combining what little evidence there is and expanding it on a continent wide basis can the process be established – and even then lack of funding means the question remains wide open to differing interpretations. The Palaeo Indian period has bcome the domain of a small number of specialists. In most parts of the world it is possible to connect Holocene occupation with pre-YD occupation simply by digging deeper beneath 10,000 year old material. In western North America such excavations are fruitless, to date – because Holocene and Pleistocene archaeological records do not connect with each other. This is completely consistent with small but widely dispersed Clovis hunters and coastal colonisation, populations  that were severely reduced by the YD impact event (whatever it was). Archaeological visibility is consistent with punctuated settlement – which is what we might expect after an extra-terrestrial catastrophe. The latter also provides an excellent explanation for the extinction of 35 genera of animals. Large animals were most susceptible to die-off, and smaller animals, in general,survived to a greater degree – as they did after the KT boundary event. After decades of debate in which alternative explanations have been agressively resisted, the YD impact theory seems to offer a realistic diagnosis of the Palaeo Indian archaeological record to a remarkable degree.
