Another Weird Shiny Thing on Mars

Hmm, so that's where I left my ball peen hammer!

I am leaning more with the pyrite or something like it explanation since its only 0.5 cm tall,

Although I give props to Arken and Hugo, Arken presented it as a living creature (nothing wrong with that BTW) and the OP is presenting it from a scientific angle with listed sources.

Think we can handle two different thread viewpoints on the subject but in the end that is for the mods to decide.
