Gobekli Tepe and the Younger Dryas Impact Hypothesis

Gobekli Tepe and the Younger Dryas Impact Hypothesis

There are an interesting series of blog posts about various ideas about Gobekli Tepe, its archaeology, and an alleged association with the Younger Dryas Impact Hypothesis on the Lateral Truth blog. They include:

http://omnilogi.com/ancient/deluge/Sweatman-and-Tsikritsis-gobekli-tepe-comet.pdf

In the same journal, Mediterranean Archaeology and Archaeometry, another paper about a fringe version of a Younger Dryas impact senario is published. The paper is:

As previously mentioned, Rebbeca Bradley also commented on Michael Jaye’s unique ideas about an Younger Dryas impact causing a truly global flood in:

Fossil Hunting on the Moon in Terrestrial Meteorites

Burchell, M.J., McDermott, K.H., Price, M.C. and Yolland, L.J., 2014. Survival of fossils under extreme shocks induced by hypervelocity impacts. Phil. Trans. R. Soc. A, 372(2023), p.20130190.
https://royalsocietypublishing.org/doi/full/10.1098/rsta.2013.0190

https://core.ac.uk/download/pdf/30704804.pdf

The abstract states:
“This is the first demonstration that fossils can survive and be transferred from projectile to target in hypervelocity impacts, implying that
it is possible that, as suggested by other authors, terrestrial rocks ejected from the Earth by giant impacts from space, and which then strike the Moon, may successfully transfer terrestrial fossils to the Moon.”
