Conglomeratic upper bioclastic unit in unconformable contact with underlying thin-bedded Bouse marl. Upper deposits filled erosional channel features. The upper unit contains common shell fragments, particularly near the base, and some reworked tufa cobbles and small boulders (K. House is pointing to some), but gravel fraction is primarily siliciclastic and locally sourced. Base of exposure is local fan gravel of unit Tfg1.
