#Geoducks (genus Panopea/#Lushootseed gʷidəq) are such icons of the #SalishSea that the pronunciation of their name has become a test of Northwesterness, and with good cause: their ancestors have been in the region for a long time. The #OlympicPeninsula has yielded several #geoduck #fossils dating back to between 20 and 30 million years ago, and this #FossilFriday I share with you all a #Miocene geoduck from the #Clallam Formation next to its modern relative, the largest burrowing #clam.
