| Outline of Final Research Achievements |
Following paleoecological studies have been conducted about crinoids (Echinodermata), the representative deep-sea sessile animals. By examining morphology and carbon isotope of the skeletons, Cretaceous stalked crinoids from South Dakota and Hokkaido are concluded as a member of cold seep environment. By an experimental taphonomy and observation of postures of fossil stalked crinoids, a new method can be found about detecting existence and absence of musculature in the arms. About the predation pressure of comatulid crinoids received from their predators, it is successfully found that quantitative data could be obtained and compared by measuring the frequency of regenerated arms of these crinoids form northwestern Pacific, northeastern Pacific and north Atlantic.
