Remarks

In the well-preserved examples of these three-armed star-shaped monocrystalline calcareous nannofossils, distinct furcations are typically observed at the ends of each arm. These furcations can vary in shape and size but are notable features that contribute to identifying and classifying these nannofossils. The furcations are particularly significant, indicating the specimens’ structural integrity and preservation quality.
