Mars fossil petrified root or distinctly layered spherule

(MarsFossils) wrote in message om...
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.

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.

Although I do not know exactly how the material shown was formed,
I do know that small particles striking an elastic surface can
cause similar patterns... or a hard material embedded in a softer
material and aggitated. It does not require life to generate
these shapes... only motion.
