| Abstract: | Size sorting of shells and valves of transported death assemblages of Mytilus edulis is shown to have taken place, and greatly affected size-frequency distributions of shell accumulations deposited in a beach environment. Selective transport and deposition of different size grades gives histograms which may be strongly skewed or multimodal, and include numerous small shells. The usually predicted bell-shaped distributions for sorted assemblages are not always produced. Little evidence of growth and mortality rates can be deduced with confidence from the transported assemblages. |
