| Abstract |
Shell beds are comparatively rare on large tidal flats near Inchon, Korea, where barrier islands, well-developed intertidal drainage channels, and landward salt marshes also are absent. Even though landward transport of non-indigenous shells is discernible, most shell accumulations evidently originate through comparatively rapid deposition of sediments coupled with gradual mortality within local populations; individual valves typically experience only minor lateral displacement. Apparent cohort size classes remain distinguishable within some assemblages. Old shells predominate among gastropod assemblages whereas new shells predominate among bivalve assemblages, implying greater rates of productivity among bivalves than among gastropods. |
