Also, look at the abstract for:

 

Burchell, M.J., McDermott, K.H., Price, M.C. and 

Yolland, L.J., 2014. Survival of fossils under 

extreme shocks induced by hypervelocity impacts.

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.”
