New Late Eocene Mollusks From Localized Limestone Deposits Formed By Subduction-Related Methane Seeps, Southwestern Washington
The trochid archaeogastropod Margarites (Pupillaria) columbiana n. sp., the mytilid bivalve Modiolus (Modiolus) willapaensis n. sp., and the vesicomyid bivalve Calyptogena chinookensis n. sp. are described from the earliest known fossil communities associated with subduction-related methane seeps.
