Glomospira kaminskii sp. nov., a new agglutinated Foraminifera from the Paleocene of the Scaglia Rossa Formation, Contessa, Italy

The new species Glomospira kaminskii is described from the Paleogene Scaglia-type assemblages in central Italy. The species is characterized by its initial glomospiral coiling, which changes during ontogeny to streptospiral or irregular. The undivided tubular chamber often meanders across the surface of the earlier test, and then may uncoil. The species also differs from other Glomospira species in possessing a finely agglutinated wall and a deeply incised coil suture. This discovery shows that the genus Glomospira may alter its coiling mode in the adult stage. The species, first reported from the Lower Eocene of the Labrador Sea, has a cosmopolitan distribution.
