Smaller than an adult hand. Found in gravel by East Fork River.
this mussel was so big! i left it in the creek because removing mussels, even if it’s just the shell, is illegal because they are an endangered species :)
Some sort of mucket. 9cm in width, 11cm in length. Found in small cobble/gravely substrate. Female. Update - plain pocketbook. Thank you all for the help with the ID!!
