Week 15. Oyster shells and jawbones

These were found at a dig in Great Bircham, Norfolk. The English didn't bother eating oysters unless they had no other seafood, but when the Romans came consumption of oysters increased rapidly - they loved them! So wherever a dig reveals clues to Roman life (or later, as in the Saxons here) you'll find lots of oyster shells.
The jaw bones are animal I think but I'm not sure what animal.
