文摘

•: The operculum of the tubular fossil Cupitheca is described for the first time.
•: The new material shows that Cupitheca is a hyolith, probably an orthothecid.
•: Cupitheca had a pelagic larval stage and a benthic adult life stage.
•: The Cupitheca operculum preserves a possible larval attachment scar.
•: The scar probably attached the larva to algae or benthic substrates.
