I just read the article in Spanish. There were about 10 technical words I did not full understand, but the gist of the article is that the remains are from 10 to 12,000 years old. They are at a place where the valley of mexico empties into the Rio Salto and flows toward the ocean. This was discovered because of excavating for a sewage plant for Mexico City which is in the valley at an altitude of 7,000 feet. Given that fact I doubt that it was either an ocean wave or ocean flood. What makes more sense is that there was a rapid melt of glaciers on the surrounding volcanoes, or a large meltdown like the Nevada de Ruiz event a few decades ago that killed over 20,000 people with a lahar. Another possibility if this was precipitated by the Firestone meteor event(s) was such earth shock that a bathtub like wave was propagated in what must have been a very large lake bed which then flushed many victims, including humans, toward the outflowing river.
There are other great bone beds in Canada and Alaska from the same time period. Some of this I first became aware of reading Velikovski, and then found from other sources since I was alert to the possibility. Can’t wait to hear more of their findings.
Thanks gleeakin. I suppose there could be any number of causes for this “deposit”. Although I’ve not studied the subject it’s my impression that lahars are generally readily identifiable. Maybe not. We don’t know much about the medium these bones were found in except there was apparently a fair amount of sand. Gravel, ash, charcoal? Splintered and mangled trees? We don’t know yet but I have my suspicions since the timing is coincident with other bone yards around the world where much of this detritus is present.
