The last of my older prints which would fit #printerSolstice2425 prompt silicon: four radiolarians of the of the spyroidea family on handmade Japanese paper. Radiolarians (or radiolaria) are a type of tiny creature -amoeboid protozoa - which produce silica mineral skeletons. They occur as zooplankton throughout the oceans and their tiny skeletal remains can be used as diagnostic fossils to date submarine sediments.
