Iron Age or Early Saxon pottery?

Just a short discussion on what is probably one of our most early and rare finds. Back in April Catherine found a very crudely made potsherd in TR39 with oolitic inclusions. Experts have seen the object and agree it's either Iron Age or Early Saxon. Had it definitely been a base or rim section it would have been more diagnostic but the most recent view is it is Early or Pagan Saxon. If it is Saxon then this is a very special find as South Gloucestershire is generally thought to be aceramic for this period.
