• Resumen

  • The Late Eocene deposits from north-western Transylvania provided a rich foraminiferal assemblage characteristic of marine shallow-water environment. Among other taxa the assemblage contains also a single-layered orbitoidal foraminifer with bilateral symmetry assigned to Droogerinella ovata (Halkyard) n. Gen., type of a new family Droogerinellidae. It is characterized by a flattened test with a biloculine embryonal stage, an axial longitudinal row of globular ovoidal chambers symmetrically developed towards the two poles and, on both sides, by hemiglobular radially altenating lateral chambers, all of them in a single, slightly vaulted plane.
