Homotrema rubrum (encrusting foraminifera) (modern; San Salvador Island, Bahamas) 1 (49719433227)

Description:

Description: Homotrema rubrum (Lamarck, 1816) - encrusting foraminifera on an eroded coral clast from the Holocene of the Bahamas. Homotrema rubrum is a common, reddish-colored, hard substrate-encrusting foraminiferan in the oceanic waters around San Salvador Island. A nearly identical, co-occurring foraminiferan is Miniacina, so identification of red encrusting forams as "Homotrema rubrum" should be done loosely. The rock itself is actually not a rock - it's an eroded scleractinian coral skeleton, composed of aragonite (CaCO3 - calcium carbonate). Classification: Protista, Foraminiferida, Rotaliina, Homotrematidae Locality: San Salvador Island shoreline, eastern Bahamas. Date: 29 March 2020, 21:01.
