Definitions

1. A type of extinct marine crustacean characterized by a bivalve-like shell, belonging to the group of seed shrimps known for their fossilized remains used in geological studies
2. An ancient genus of tiny aquatic arthropods with calcareous shells, typically studied through their fossilized carapaces found in sedimentary rock layers
3. A fossilized small crustacean species identified by their distinct shell morphology, commonly utilized in paleontology and stratigraphy to date marine sediment deposits

Etymology: The core of this term is a place name. "Cythere" is the Latin form of Kythera, a Greek island associated with Aphrodite, who was also called Cytherea. Naturalists used Cythere as the name of a genus of ostracods, the bivalve-shelled crustaceans commonly called seed shrimps, and the family named after that genus is Cytheridae. The "-id" ending is the zoological marker of a family, borrowed from the Greek patronymic suffix meaning "descendant of." "Lepto-" comes from Greek "leptos," meaning thin, slender, or fine. Combined with the Cythere stem, the name points to a group of slender-shelled relatives of that genus. The name is a technical coinage in the taxonomic naming system rather than a word with a long popular history.

Synonyms: ostracod, microscopic crustacean
