We did an XRF to look for sulphides, I was also thinking of pyrite, but they are absent. Seems to be just Iron.

Has anyone ever seen anything like this? I can't yet share too much about the context, but it is well into the stone age.

so what are these yellow things. We currently think they were organic objects, covered with red ochre and somehow "fossilized" in iron deposits. In detail we can on some spots see structures that look like bone, and other spots we have clear plant fibres/cells.

Well, 6 really, we shouldnt dismiss Earth just yet.
