Mars Fossils, Pseudofossils or Problematica?
http://aix1.uottawa.ca/~weinberg/mars/
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. Michael |

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. Just Guessing.................William |

Back when Mars still had a magnetic field to protect its atmosphere from loss. What is the relationship to having a magnetic field and preserving the atmosphere? Why wouldn't the atmosphere be lost mainly because the gravity is so small, 0.35 that of Earth. What does the planet's magnetic field have to do with it? Or did I skip that class? Michael |
