If you wish to use the official Irish SMR definition, then no bullauns should be on TMA:
The term 'bullaun' (from the Irish word 'bullan', which means a round hole in a stone, or a bowl) is applied to boulders of stone with artificially carved, hemispherical hollows or basin-like depressions, which may have functioned as mortars. They are frequently associated with ecclesiastical sites and holy wells and so may have been used for religious purposes. They date to the early medieval period (5th - 12th centuries AD)
This definition is an old one, and was clearly written by someone who hadn't studied them in the wild, but was just winging it.... so it's up to TMA to decide on their fate.
