Rogerella

Rogerella is a small pouch-shaped boring (a type of trace fossil) with a slit-like aperture currently produced by acrothoracican barnacles. These crustaceans extrude their legs upwards through the opening for filter-feeding.^[2][3] They are known in the fossil record as borings in carbonate substrates (shells and hardgrounds) from the Devonian to the Recent.^[4]
