美国华盛顿州西部的林肯溪、马卡和皮什特地层的新生代深水沉积物中含有沉没的浮木和鲸骨，这些浮木和鲸骨被无脊椎动物殖民，这些无脊椎动物在很大程度上依赖于这种类型的短暂栖息地。这些化石木-和鲸鱼-秋天动物群产生了六个新的软体动物物种，似乎是这些生物源微生境特有的，除了一个物种也出现在冷渗石灰岩中。新的腹足类物种是新脐类Leptogyra squiresi，颊科Colus sekiuensis，异腹足类Xylodiscula okutanii，新的双壳类物种是原鳃类“Nuculana”posterolaevia，mytilid Idas？奥林匹库斯（Olympicus）和异齿Thyasira xylodia。
Cenozoic deep−water sediments of the Lincoln Creek, Makah, and Pysht formations in western Washington State, USA, contain sunken driftwood and whale bones that were colonized by invertebrates which largely depend on this type of tran− sient habitat. These fossil wood− and whale−fall faunules yielded six new mollusk species that appear to have been en− demic to these biogenic microhabitats, except for one species which also occurs in cold−seep limestones. The new gastro− pod species are the neomphalid Leptogyra squiresi, the buccinid Colus sekiuensis, the allogastropod Xylodiscula okutanii, and the new bivalve species are the protobranch “Nuculana” posterolaevia, the mytilid Idas? olympicus, and the heterodont Thyasira xylodia.
