#cerastoderma

common cockle (Cerastoderma edule) shell half, about a third of the size of the average adult shell.

flat periwinkle (Littorina obtusata) shell, another white one, much larger this time. 

3 netted dog whelk (Tritia reticulata) shells, half size or smaller than the average adult, the one on the right only 7mm long. 

3 snails of uncertain ID, either young dog whelks (Nucella lapillus), or the same species found in St Ives last month (possibly Lacuna crassior).

another snail of uncertain ID, so far I’m guessing it’s a very young turban top shell (Gibbula magus).

3 European, or spotted cowrie (Trivia monacha) shells. 

tube of cemented sand grains and shell fragments created by the sand mason worm (Lanice conchilega).

3 ceramic fragments: 1 of the usual warm grey with cool grey lines material; 1 similar, but with lines closer together; and 1 blue, rounded, possibly the edge of a container.

5 weathered shell fragments from dog cockles (Glycymeris glycymeris), and one from some other bivalve.

1 striped venus clam (Chamelea gallina) shell half.

6 pieces of glass - not as good quality as what can be found between Penzance and Marazion, but frosted and without imperfections.

Common periwinkle (Littorina littorea).

Common cockle (Cerastoderma edule) shell half.
