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 seep...
