Is 1200 years long enough it would be sterile? Like, no original bacteria or parasites?

This is my bread and butter. Peat is anoxic. It's great for preservation and you get tonnes of stuff that doesn't preserve elsewhere. Google "Must Farm, UK" I'm an archaeologist that does environmental work in these kinds of environments. Peat preserves eyelashes on bog bodies, it's nuts. Dissolves other stuff though due to the acids. I've got a diagram somewhere give me a bit.

Well the human gut is anoxic too, so that shouldn't be a problem for the gut-bacteria in that log and in the bog mummies. I think it way more likely that the sphagnan and the other tannins in peat-bog-water conserved this as well as the bog bodies.

It's the eggs you count for parasites. I do this for a living, my friend. I posted a diagram. Soft bodied insects don't preserve well.

That is extremely cool and I don't doubt your expertise in the slightest. Was only commenting about that anoxic conditions alone wouldn't necessarily preserve the bog mummies, but that the acidic conditions and tannins are likely more important.

[–] fossilesque@mander.xyz 1 points 9 months ago

Ah yes, I got confused for a minute. The lack of oxygen is the most important for preservation in general, but specifically for skin etc., the acid and tannins keep that.

Bog bodies are dope as hell.
