文摘

Death assemblages of molluscs are often far more diverse than living communities. Shells of allochthonous taxa strongly increase dead diversity. Rare taxa can be recovered in the dead record through a process of time-averaging. Death assemblages may help to identify recent extirpations. Carefully filtered death assemblages provide a unique record of local biodiversity.
