All the "links" are missing.
The surviving creatures may well not have created fossils ! It is
only the process of being caught up in the big flow that allowed
fossils to be formed. So creatures from Mars that survived the
transportation probably lived in water and adapted to Earth's
gravity over generations. Then the next Mars-Earth close approach
formed lamination sediments with Martian and Earthian creatures
mixed in with this flow, and they formed fossils. And as suggested
before, as electrical conditions moderated, no longer did Mars
creatures or sediment reach Earth. This suggests that the Cenozoic
sediment would be in some way different from the Mesozoic sediment
because they lacked Martian rocks.(Other than the fossil differences)
In the following Figure 6.18 shows that the Li/Al ratio of Precambrian
rocks is about the same as Cenozoic rocks, whilst other rocks generally
have a higher ratio : here
This suggests that the Cenozoic rocks were formed from Precambrian
rocks, and these would have come from the bottom of the oceans. And
if the Martian rocks had a higher Li/Al ratio then the mixing of
these rocks with the Earth ocean bottom rocks would explain the
higher Li/Al ratio in the Mesozoic sediment. So a little evidence.
The Martian rocks would be deep crust or mantle rocks.
So now we have the laminar sedimentation process explaining the
missing links. We have dinosaurs coming from Mars which explains
their giant size. And also the original Cambrian rocks contained
a great variety of fossils and some very advanced and complicated
creatures like the trilobites.http://en.wikipedia.org/wiki/Trilobite"Many trilobites had complex eyes; they also had a pair of antennae."
This suggests that Mars had life for a long time, when along came
Earth and maybe Saturn, and a very electric Saturn System was formed.
And the pretty old Martian creatures were swept to Earth along
with lots of Martian rocks,where they mixed with Earth (now oceanic)
Precambrian rocks and the Earth Cambrian rocks formed.
So the theory is going OK !
