|Description||Clinocardium nuttali, basket cockle fossil dating from between 1.5 million years ago to .75 million years ago commonly found at low tide in littoral (sandy and muddy bottom) or sub-littoral (open bay, muddy marine) zones. Fossil specimen is stone-colored, with some patches of white and some areas with a reddish tinge (likely indicating the presence of iron oxide). Faint ridges are visible on one side, running the length of the shell. Underside surface is irregularly shaped, with a partial shell cast and other shell fragments throughout. Some reddish patches are visible.|
