This "sand" is actually not sand at all. Rather than rock fragments, it is made of tiny, star-shaped fossils. Each piece is a fossilized exoskeleton of a sea creature from the Foraminifera group. These amoeba-like organisms have existed for about 542 million years, and over 50,000 species are known. This particular sample is from Ishigaki Island in Okinawa, Japan. Be sure to examine these fossils under a magnifying glass or microscope for a closer look!
