我们整理了1935 ~ 1995年在日本更新世沉积物中报道的苔藓虫类群。我们的清单在1980年Sakagami等人的清单上增加了许多更新世记录:尽管自1980年以来只有少数额外的更新世苔藓虫记录被发表,但许多以前被认为是上新世时代的沉积物现在被更准确地定为更新世。其中包括濑田队、滨田队、广濑队、大坂队、石川队、泽渊队、海泉队和大马队。我们的列表包含358个分类群,其中包括97个来自更新世日本的新分类群。以往的研究主要集中在日本的四个地区:1)本州中部的保佐半岛,太平洋一侧;2)津加鲁海峡附近的北海道西南部、本州北部;3)日本海本州中部的诺东半岛和新泻;4)九州南部西南群岛的菊海岛。给出了各地区和各地层报告的总分类群数和新分类群数,并比较了各地区间的相似性。我们报告了两个地区新发现的更新世矿床:Setana Fm;在北海道黑松井附近,以及大江和“北有岛”公司。位于九州岛原半岛。更新世苔藓虫在日本相对广为人知,随着分类分辨率的提高,可以为研究气候变化对无根底栖海洋生物群落的影响提供一个“模型系统”
We compiled a list of bryozoan taxa reported between 1935 and 1995 from Pleistocene deposits in Japan. Our list adds many Pleistocene records to the 1980 checklist of Sakagami et al.: although only a handful of additional Pleistocene records of bryozoans have been published since 1980, many deposits previously considered to be of Pliocene age have now been more accurately dated as Pleistocene. These include the Setana, Hamada, Hirose, Daishaka, Shibikawa, Sawane, Haizume, and Omma Formations. Our list contains 358 taxa, including 97 new to science described from Pleistocene Japan. Previous studies have been concentrated in four regions of Japan: 1) Boso Peninsula, central Honshu, Pacific side; 2) SW Hokkaido and N Honshu in the vicinity of Tsugaru Strait; 3) Noto Peninsula and Niigata, central Honshu, Sea of Japan; and 4) Kikai-jima Island in the Nansei Archipelago south of Kyushu. We present the number of total taxa and new taxa reported per region and formation, and compare the similarities among regions. We report newly discovered Pleistocene deposits from two regions: the Setana Fm. near Kuromatsunai, Hokkaido, and the Oe and “Kita Arima” Fms. on the Shimabara Peninsula, Kyushu. Pleistocene bryozoans are relatively well known in Japan, and with increased taxonomic resolution can provide a ‘model system’ for investigating the effects of climate change on assemblages of sessile benthic marine
