A newly published core from southern Sweden separates the Laacher See eruption from a distinct platinum- and microspherule-rich Younger Dryas Boundary fallout layer.
The Cosmic Tusk has a new look. And, after a year or so on life support, a new lease on life.
The scientific history of Wonderkrater makes this new paper especially compelling. The platinum anomaly was not originally discovered by the Comet Research Group or by scientists closely associated with the Younger Dryas Impact Hypothesis. It...
Some scientific controversies require satellites, laboratories, expeditions, and million-dollar equipment. Others require a camera, a GPS unit, a range pole and free weekend. The Arlington Canyon exposure on Santa Rosa Island belongs in the second...
Two Younger Dryas boundary papers were recently retracted by PLOS ONE. Within hours, critics began circulating the notices as though they represented the long-awaited collapse of the impact hypothesis. They do not. Let’s look plainly...
This has been a satisfying week for the Younger Dryas Impact Hypothesis. For years, critics of the hypothesis demanded two things above all else: “show us shocked quartz at the boundary, and show us an...

A masterful and comprehensive effort here from respected Comet Research Group co-author, Bill Mahaney. Much of the discipline-specific text is hard for the Tusk to fully grasp, and I have had no time to properly review, but I have asked Bill to provide a layman's summary of...
