Globorotalia albeari

Citation: Globorotalia albeari Cushman and Bermudez 1949
Rank: Species
Type locality: under bridge in the highway, Central San Antonio, Madruga, Habana Prov., Cuba (Bermudez sta. 76).
Type age: Paleocene
Type sample and level: Madruga formation [from stratigraphic level within subsequently described (1957) Gl. pseudomenardii Zone, Madruga]
Holotype Repository: Washington; USNM
Type & figured specimens: 47413

Linked specimens: USNM-47413 USNM-47414

Current identification/main database link: Igorina albeari (Cushman and Bermudez 1949)


Notes: The species can also be cited Globorotalia (Globorotalia) albeari, and it should have been thus cited by Cushman & Bermudez 1949 since they differentiated Globrotalia sensu strictu from Globorotalia (Turborotalia). [see ICZN Art 44 Nominotypical taxa].

Original Description
Test very small for the genus, strongly biconvex, dorsal side showing all the coils and ventral side only the last-formed whorl, periphery somewhat rounded; chambers not very distinct, 9 to 10 in the last-formed whorl, only slightly inflated ventrally, increasing very gradually in size as added; sutures fairly distinct but only slightly depressed except in the last whorl on the ventral side, rather strongly recurved on the dorsal side; wall slightly spinose, coarsely perforate; aperture an elongate opening on the ventral side of the last-formed chamber extending from nearly the inner end to the periphery and with a distinct thin lip.

Size: Diameter 0.30-0.32 mm; thickness 0.20 mm.

Etymology: The species is named in honor of Ing. Jesus F. de Albear of the Cuban Geological Survey.

Extra details from original publication
This species differs from G. praemenardii Cushman and Stainforth in its smaller size, more numerous chambers, more strongly biconvex test, and less umbilicate ventral side.
The species has been found only in samples of the Madruga formation where it is a good marker.

More precisely Globorotalia (Globorotalia) albeari Cushman & Bermúdez, 1949

That seems a bit debatable, it is always given in the paper as Globorotalia albeari, but arguably they should have used the name Globorotalia (Globorotalia) albeari since they differentiated Globorotalia ss from Globorotalia (Truncorotalia). However, my general practice in the catalog is to document the names under which the species were described rather than my interpretation of the correct name (with some exceptions...)
