Hauerinidae

Hauerinidae is a family of foraminifera, which are single-celled eukaryotic microorganisms. These marine protozoans are characterized by their agglutinated tests, meaning they construct their shells from particles of sediment collected from their environment. The Hauerinidae family belongs to the superfamily Miliolina, a group known for its calcareous, imperforate tests, although the classification and specific characteristics can vary within the broader context of foraminiferal taxonomy.

The tests of Hauerinidae are typically small and can exhibit various shapes, often appearing lenticular, compressed, or even somewhat fusiform. They are commonly found in marine sediments, particularly in shallow to moderate water depths, and are considered benthic organisms, living on or in the seafloor. Their distribution is widespread across different oceanic regions. Fossilized remains of Hauerinidae are valuable in paleontology for biostratigraphy and paleoenvironmental reconstructions, as their presence and abundance can indicate specific geological periods and marine conditions. Research on this family contributes to our understanding of marine ecosystems and the evolution of foraminifera.
