Hi folks, some information gleaned from other forums.
The Martian fossil that we have all seen photos of is looking a little more interesting than before.
It seemes that life on Earth has the curious ability to concentrate lighter isotopes. For instance, the ratios of C12 to C13 and C14 are increased. Mineral grains in ancient rocks were found to be ancient bug fossils, a microscopic grain of the mineral apatite had a small grain of carbon material in its core. The core was several percent higher in C12 that the surrounding rock. This indicates that it was was living material. Well, the same has been found to be the case with the Martian meteorite fossil. It is higher in C12 than it should be. To me, this is indicative of life processes, once taking place. If anyone has any other info regards this, please tell.
