| Outline of Final Research Achievements |
As a result of examination on fossils from the Paleocene Katsuhira Formation in Urahoro Town, Hokkaido, it has been elucidated that the fossils are corresponded to wood-fall communities which might live in 200 to 500 m of depth. In these communities, several end-Cretaceous survival taxa have been found. Although their species diversity is similar to those of the post-Eocene seep communities, some of them show higher than the latter. Comparing with the post-Eocene wood-fall communities, they has much more species for each localities than the post-Eocene ones. Moreover, the above end-Cretaceous survivors have not been recorded from the post-Eocene deposits in northern Pacific. From these, it can be stated that PETM caused big change of deep-sea wood-fall communities by the extinction of some dominant taxa such as aporrhaid gastropod and decreased their species diversity for each localities.
