I made up the above web page to publicize the possibility that the
Mars microscopic imager pictures taken by the Opportunity Rover at
Terra Meridiani, and especially at the "El Capitan" and "Guadalupe"
sites on sols 28 through 34 - the last week of February 2004 - show
fossiliferous rock.

If these are fossils, which is not certain but possible, then it is
likely these organisms evolved during the watery epoch of Mars
hundreds of millions of years ago. The Opportunity Rover seemed to
have stumbled upon a marine reef of hard-shelled but eroded organism
debris. The organism whose shells formed the eroded "Y" and "V" shaped
cavities seem to be somehow associated with the ubiquous blue stone
balls found at the site. The "Y" and "V" shaped cavities represent
negative space left over when these hard structures were surrounded by
clay and then dissolved out. This phenomenon is very common in
terrestrial fossils.

Have a look. I hope you find it interesting.

Timewise the "watery" period could have been over
3000 million years ago. Back when Mars still had a
magnetic field to protect its atmosphere from loss.
I'd guess that the atmosphere would have been high
to carbon dioxide to keep the temperature up.
Perhaps there was life even complex life.
