After a bit we were diverted by an unexpected feature that was running away from the wall/rampart. No clue as to what it was, but it needed exploring. After a morning mostly free of artifacts a few "bits and bobs" turned up.
A "game counter". At least that is what these hand carved bits of worn out pottery get called. Their exact function is unclear.
No, not another phallus. This is iron and was some sort of bolt with a loop on it. And of course various bits of pottery. A nice fragment here, it had knocked around a long time before ending up in a post Roman mystery feature.
