Pictures from my Ordinary High Water Mark (OHWM) Training

Anyone have any idea what these little guys are? They seem to be cases (not really hard enough to be considered shells; def. not mineralized) of some type of filter feeding organism. They were attached to the bottom of a piece of driftwood, and the bay that they washed up from was probably on the very high end of brackish (not sure how much the Samish River dilutes the seawater this far from the mouth....).


The erosive power of water (or, rather, sediment in the water) has sculpted this piece of driftwood.
