Fossil Hunting on the Moon in Terrestrial Meteorites 26JAN2019

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.”
