颗石藻(钙质超微浮游生物)是球状的单细胞浮游生物海藻,在现代大洋的食物网中有重要意义。这些海藻分泌颗石藻,支撑组分为方解石,直径1~10μm,形成于高尔基体内并挤压后覆盖于细胞表面。由于颗石鞭毛藻很小(20μm),归属于超微浮游生物类。它们在晚白垩世的产量比现代高,形成大
Coccolith (calcareous superplankton) is a globular, single-celled plankton seaweed that is of great importance in the food web of modern oceans. These algae secrete coccolith, the supporting component of calcite, diameter 1 ~ 10μm, formed in the Golgi apparatus and squeezed after covering the cell surface. Due to its small size (20μm), it belongs to the superficial plankton class. Their production in the late Cretaceous is higher than in the modern age and forms large
