| An Analysis of Dinocysts of Cenomanian-Turonian Transition Phase in Asturias,Spain,and the Palaeoenvironmental Interpretation |
| The study section located in Asturias, northwestern Spain, contains very rich dinocysts comprising a total of 114 species and subspecies. Cyst abundance and species diversity show obvious decrease near the Cenomanian Turonian boundary. Other semiquantitative data related to the palaeoenvironments also show dramatic changes, indicating that fluctuations were obviously influenced by Oceanic Anoxic Events. |
