Summary

[edit]
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 white area is bleached, encrusting calcareous algae.

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
