The "marine reptile" featured at the beginning of the video reminds me so much of the dead seal my wife and I came across walking along the UK coast. It was already in a state of some petrification - the skin having turned into something like leather. I could well imagine given a few hundred thousand more years it could look like the "marine reptile".
I'm definitely keeping an open mind on this. If Mars suffered some unbelievably catastrophic event e.g. maybe a highly oxgenated atmosphere caught fire in a kind of global Apollo fire event or the planet was subjected to some particularly severe asteroid bombardment, life could have been ended in a matter of a few sols.
For me there is a pressing need to get people to Mars to investigate all these interesting "rocks" or "finds".
