The causes that led to the extinction of most of the larger mammals – also referred as Megafauna- that roamed the Pleistocene world are still highly controversial and fiercely discussed. 35 mammals and 19 bird genera became extinct during the transition from the Pleistocene to the Holocene 10.000 years ago, in the last decades many different hypotheses were proposed to explain this event, from human overkill to climate change, more unusual was an idea largely publicized by mass media in 2007.
Geophysical studies presented in spring 2007 suggested that perhaps an extraterrestrial meteorite vaporized in the Earth’s atmosphere caused the extinction of the North American Megafauna and associated human cultures some 13.000 years ago. This idea was not all new, already in 1990 archaeologist William Topping found in Michigan spherules in glacial sediments – supposedly of extraterrestrial origin, even if he and nuclear physicist Richard Firestone suggested a nearby supernova as origin of these features. Based on this discovery Firestone later developed as alternative explanation the meteorite hypothesis, according to him the hypothesis could not only explain the extinction of the large mammals, but also the observed fluctuation of the Younger Dryas at the end of the Pleistocene and the beginning of the Holocene. The Younger Dryas is a 1.500 years (12.900-11.600 cal.B.P.) long cooling event, recognized especially in Europe by the advance of glaciers and a vegetation shift. The Younger Dryas is a “freak” event – unique of the termination of the last glacial – similar events are not recorded in the ice cores of Antarctica for the previous glacial phases.

Whether the Mayan calendar has any more signicance in my daily affairs than the Chinese calendar does not have to be so. We've made a big deal out of it and so will I by celebrating it. Any time is a good time for a fiesta if one decides to make it so.
