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.”
