Seashells from Swansea Bay

This assortment of shells was found on the sandy muddy shore of Swansea Bay. They include Common Cockles, Common Mussels, Saddle Oysters, Tellins, Common Winkles, Dog Whelks, Common Whelks, Sting Winkles, Necklace Shells, and Limpets, along with some pieces of beach glass and a common whelk shell entirely covered by the chalky tubes of the marine worm Pomatoceros triqueter.

The pictures below show views of the beach where I picked up the shells among the drifts of shells on wet sand at Swansea Bay one bright, frosty, winter morning.
