| Research Abstract |
This study aims at clarifying calcareous nannoplankton evolution based on the analysis of calcite crystals forming calcareous nannofossils. The main results are as follows;
1) Major calcareous nannofossil taxa had diversified immediately after calcareous nannoplanktons appeared at the late Triassic.
2) The events of some morphologic and crystallographic changes may coincide with past global environmental changes.
