Need's a much higher resolution shot but it does look like a fossil to my eye's though of course there are many other thing's that it may be as well,
though it remind's me of a rib cage like structure and a curled skeletal possibly spine or spine analogue of a vertebrate type creature.
It is theorized that MARS was indeed once extremely suitable for life and there was a stratification process similar to that on earth including water
born deposits and clay's (alluvial deposits) and sand stone but as yet I don't think they have found any limestone which here on earth was created by
life and is essentially the compressed bone's and shell's of ancient sea creature's mainly, diatom's etc.
There is plentiful evidence from MARS past before it's atmosphere was stripped way and possibly from a time when MARS may have had a far more
protective magnetosphere that it once had rain fall and river's, lakes and sea's so a full weather cycle was present.
This mean's weather driven water erosion and leaching of minerals from rock's, atmosphere that was potentially far more suitable to life than is now
there, the remaining atmosphere being largely carbon dioxide would also point to the lost atmosphere having had at least a percentage of oxygen, the
remaining carbon in the carbon dioxide also suggest's that a carbon cycle would have been possible.
MARS is of course much smaller than the earth but that does not preclude the possibility of life there and even now there may still be lingering
microbial life in deep strata living off chemo synthetic process just as have been found here on earth below several kilometers of solid rock so even
today it may not be as dead as we assume, indeed life may even have began earlier there than on earth as MARS may have been habitable and suitable for
life far earlier than the earth was.
Another potential candidate in the solar system is Earth's twin Venus, now too hot but it may not have always been so and indeed there could have
been a period up to maybe two or more billion years during which time this near twin of the earth may also have had a liquid water ocean and it's
atmosphere may not have been so deadly, we know from earth that about 750 million years ago the sun may have warmed up ending a 1 and a half billion
year period of super ice ages on the earth (Snow ball earth theory - I am conjecturing that it may have been increased solar output that ended this
period during which the earth is hypothesised to have frozen over right to the equator's from 2.25 billion to 750 million years ago) and potentially
it's solar wind also increased, this coupled with MARS weak magnetosphere may have been the death blow for both MARS and the much closer to the sun
plant of VENUS, the increased solar wind may have taken thousand's or million's of years to strip MARS remaining atmosphere away but the cooling
planetary core of the small world and it's weakened magnetic shield probably also exposed any surface organism's to increased solar and cosmic
radiation meaning that many life form's had they existed would likely have gone extinct even while MARS still had sufficient atmosphere for them to
So possible and perhaps it is something NASA should take a closer look at.
