Description
This specimen of radiolarian (Anthocyrtis sp.) is from Mount Hillaby on Barbados and dates to the Eocene (34-56 million years ago). Scanning electron microscope, magnification 7001 (when 15cm wide). The Radiolaria, also called Radiozoa, are protozoa that produce intricate mineral skeletons made of silica, typically with a central capsule dividing the cell into the inner and outer portions of endoplasm and ectoplasm. They are found as zooplankton throughout the ocean, and their skeletal remains, or tests, make up a large part of the cover of the ocean floor as siliceous ooze.
