Lithology and environment
Primary lithology:very coarse,pebbly,shelly/skeletal poorly lithified sandstone
Lithology description: Described as "impure limestone" by Hatai but the Coptothyris assemblages are in pebbly-granule coarse sandstones, partly with impure limestone, according to Sato (1991). It is likely that the impure limestone are more shell-rich intervals of the sandstone.
Environment:shoreface
