| Abstract |
A new species of serpulid tube worm, Metavermilia (Vepreculina) gollieti sp. nov., is based on tubes found in the late Eocene lower part of the Lincoln Creek Formation exposed along the Middle Fork of the Satsop River, Mason County, Washington State. Metavermilia (V.) gollieti differs from other species of the subgenus Metavermilia (Vepreculina) by its relatively large tube diameter, possession of 5 to 7 sharp longitudinal lines of granula, with a tube cross-section tunnel-shaped posteriorly and pentagonal at the aperture. Metavermilia (V.) gollieti extends the known geochronological range of the predominately Cretaceous subgenus Metavermilia (Vepreculina) from the Barremian to the late Eocene, only the second Cenozoic occurrence because there is the possiblity that ‘Serpula’ granosa from the Miocene (‘Tortonian’) may belong to Vepreculina. At the least, the new Eocene species fills a long gap in the geologic record of Vepreculina midway between Maastrichtian and Miocene as well as being the first record of the subgenus in North America. |
