Cymatiosphaera is a species of Acritarch, an organic microfossil from the Neogene period. Some Acritarchs are thought to be fossilized cysts of dinoflagellates, a type of marine plankton with two flagella that propel it through the water. Dinoflagellate cysts, like bacterial spores, are a dormant zygotic form of the organism that wait around until conditions are right to revive, and are therefore plentiful among marine sediment microfossils.
The weight of an individual earring is approximately 5.4g. and they are 1.8 cm in diameter.
