Cladococcus viminalis

Radiolarians like Cladococcus viminalis produce extremely complex silica tests of spines and pores that are laid down in a well-defined geometric pattern. The spines aid buoyancy and the pores provide outlets for cell material, called pseudopodia, which engulf any food that becomes trapped on the spines and carry it to the center of the cell to be digested. Cladococcus viminalis is a polycystine radiolarian, which are the most commonly fossilized radiolarians and are frequently found in chalk and limestone rocks.
