Taxonomy

Citation: Globoconella panda (Jenkins 1960)
Rank: Species
Basionym: Globorotalia menardii subsp. panda Jenkins 1960
Synonyms:
Variants:
  • Globorotalia ichinosekiensis Takayanagi and Oda is similar to the southern Pacific species Globorotalia panda Jenkins in the possession of a strongly convex spiral side and a nearly flat umbilical side. It is distingushed from G. panda by its thinner wall and carina, and less strongly curved sutures on the spiral side." [Hayashi et al. 2003]

Description


Test morphology: Test low trochospiral, spiral side convex, umbilical side concave to almost flat, equatorial periphery slightly lobate, axial periphery acutely angular with a distinct thick keel; chambers strongly compressed, five in the final whorl, increasing rapidly in size; sutures on spiral side limbate strongly recurved; on umbilical side radial, depressed; surface smooth on spiral side, perforate, small pus- tules on the umbilical side; umbilicus small, aperture a very low arch bordered by a rim or lip, interiomarginal, extraumbilical. [Kennett & Srinivasan 1983]

Biogeography and Palaeobiology


Geographic distribution: Temperate to warm subtropical. [Kennett & Srinivasan 1983]

Phylogenetic relations: Gr. (G.) panda is distinguished by its convex spiral side, flattened umbilical side, and a well developed peripheral keel. Gr. (G.) panda evolved from Gr. (G.) praescitula in temperate waters and is closely related to the Gr. (Menardella) archeomenardii-praemenardii plexus of the tropics. [Kennett & Srinivasan 1983]
