"Clovis Comet" Killed by Volcano

The final nail in the coffin of the "Clovis Comet" hypothesis?

Ancient sediment found in a central Texas cave appears to solve the mystery of why the Earth cooled suddenly about 13,000 years ago, according to a research study co-authored by a Texas A&M University professor.

Michael Waters, director of The Center for The Study of the First Americans and Distinguished Professor at Texas A&M University, and colleagues from Baylor University and the University of Houston have had their work published in Science Advances.

Some researchers believed the event -- which cooled the Earth by about 3 degrees Centigrade, a huge amount -- was caused by an extraterrestrial impact with the Earth, such as a meteor collision.

But Waters and the team found that the evidence left in layers of sediment in Hall's Cave were almost certainly the result of volcanic eruptions.

That coffin was nailed shut a long time ago. Especially since every strewnfield cited can be connected to a earlier or later impact and a whole bunch of people were caught lying in their papers.

could there be a impact followed by vulcanism?

Not saying this volcano is the cause, but it did erupt around 12,900 bp.
