Species Chiloguembelina crinita Glaessner 1937


Diagnosis / Definition:
Pearson et al. (2006):
DESCRIPTION. See Olsson and others (1999) for a more complete description and discussion of this species.
Discussion / Comments:
Pearson et al. (2006):
DISTINGUISHING FEATURES.- Distinguished by having a more rapidly flaring test outline and more inflated chambers than other chiloguembelinid species. The aperture is asymmetrically positioned on the chamber face and the bordering aperture lip increases in width as it extends toward the lateral chamber margin (see Olsson and others, 1999, for additional information). STRATIGRAPHIC RANGE.- Upper Paleocene through middle Eocene (Zones P4-E9) based on study of samples from DSDP Site 390A on Blake Nose (Huber, pers. observ.). Specimens of C. crinita have been rarely reported from upper lower and lower middle Eocene sediments probably because of its small size and taxonomic confusion with other chiloguembelinid species.
