Brachidontes exustus
Shells and the chain of egg cases from which they came
Petricola pholadiformis -- These are two different shells, so small that I could only pick them up by wetting my finger.
Donax parvulus -- This coquina is equally small but less fragile because it is intact.
Lunarca ovalis -- This is an equally small ark shell.
Petricola pholadiformis -- extremely small
Astyris lunata -- This is the smallest shell, so small that it felt like a large grain of sand between byssal threads that I pulled off of the shell above it. Note thread sticking out on right edge of above shell. Below this photo I have pasted a copy of the same species of shell, larger and easier to see and photograph, from this web page: Microscope Gastropod Photos.
