Thanks Renfield for this one in FReepmail: New study shows Clovis-age impact theory is still possible -- Past Horizons -- The new analysis did, in fact, isolate large quantities of the "microspherules" at the involved sites where the challengers previously reported none. Lead author Malcolm A. LeCompte, an astrophysicist at Elizabeth City State University in North Carolina, said the findings support the climate-altering cosmic impact, but his team have still stopped short of declaring this as proof of the event.
