Mars fossil petrified root or distinctly layered spherule
"MarsFossils" wrote in message m... The image below shows either a fossilized root or an Opportunity spherule with very distinct three part layering. Both are about 3 mm in diameter. http://aix1.uottawa.ca/~weinberg/mar...root_m_028.jpg What do you think it is? It is the first spherule I have seen with such a distinct core and layers. Look also at my Mars fossils web page. http://aix1.uottawa.ca/~weinberg/mars/ best, Michael It's just a weathered spherule (a concretion).
