Doesn't excuse our carelessness with our rheritage though.
There's another point. It's our climate, again.
We have very, very little organic preservation in this country. Everything rots in our temperate climate. We don't get preservation in ice (like Oetzi or the Greenland finds) and we don't get preservation by dessication such as the sites in the Middle East.
We have finds in very specific situations; anaerobic wetlands or wet soils, some bone in shell middens, where the chemical background supports the minerals in the bones instead of leaching them out, and very, very, rarely in dry-ish, mineral rich, caves.
That's it.
Otherwise our organic archaeological record is incredibly poor, however, very occasionally we get fragments of textiles preserved where they have lain against copper rich metalwork, such as brooches or belt buckles….you know ? the pieces the metal detectorists rip out of the ground
Bogs preserve stuff like butter, and in effect tan skin (the bog bodies) but the bones are leached out and reduced to collagen which, like jelly, slowly disperses, (that's why the bodies all look so crumpled; their bones have gone to mush), and woollen fabric. Linen doesn't survive well in bogs, it simply rots. Linen survives dry though, which we don't get, or against the copper rich metals, bronze, brass, etc.,
It all just reinforces the need for care, for being aware of, and recording stratigraphy.
If you're looking for Roman, and you hit Medieval, tough. You have to work your way through the Medieval and record it properly as you go, before you can get to the period you're actually looking for.
Doesn't work that way for metal detectorists, does it ?
