Close to the end of the last ice age there was a sudden disappearance of many mammalian species which some paleontologists say was the most severe since the disappearance of the dinosaurs 65 million years ago. In North America 95 percent of the megafauna became extinct, these being predominantly mammals having body weights greater than 25 to 50 kilograms. But even small animals were affected, as in the disappearance of 10 genera of birds.
Although North America was most affected, it had a severe impact also in Europe, Siberia, and South America. The cause of the extinction has long remained a mystery. Theories that have been put forth have ranged from overkill by North American paleolithic hunters to the impact of a large comet or swarm of meteors. But all have been shown to have serious flaws.
Now, Starburst Foundation researcher Dr. Paul LaViolette has found evidence that this mysterious die-off may have had a solar flare cause. In his paper published this week in the journal Radiocarbon, LaViolette concludes that a super sized solar proton event (SPE) impacted the earth about 12,900 years ago (12,837+/- 10 calendar years BP).*
He notes that this date roughly coincides with that of the Rancholabrean termination, a time boundary beyond which the numbers of extinct megafaunal remains are found to sharply decline. Read the full story here.
