Species Turborotalia ampliapertura Bolli 1957


Diagnosis / Definition:
Pearson et al. (2006):
DESCRIPTION. Type of wall: Smooth, to weakly cancellate, frequently densely pustulose; tendency to defoliate. Test morphology: Moderately high trochospiral, compact globular test with 3-4 chambers in final whorl. chambers inflated, appressed and embracing, increasing moderately in size; outline lobulate or rounded in edge view; dorsal sutures slightly curved, depressed; aperture a high arch, approaching circular, in umbilical-extraumbilical position; umbilicus wide and deep; ventral sutures moderately curved, depressed. Size: Holotype length 0.49 mm, width 0.29 mm.
Discussion / Comments:
Pearson et al. (2006):
DISTINGUISHING FEATURES.- Turborotalia ampliapertura is distinguished from T. increbescens by the wider, more open umbilicus, more umbilically centered aperture and more globular chamber shape. DISCUSSION.- Turborotalia ampliapertura is a useful zone fossil in the lower Oligocene (Bolli, 1957b). Blow and Banner (1962) and Blow (l969, 1979) distinguished the supposed contempdraneous homeomorph Globorotalia (Turborotalia) pseudoampliapertura on the basis of differences in wall texture. The holotypes of both taxa are illustrated here by SEM for the first time (PI. 15.2, Figs. 1-3 and P1. 15.2, Figs. 9-1 l), as well as better preserved specimens of ampliapertura from the type Cipero Formation supplied by F. Rogl (PI. 15.2, Figs. 4-6). According to Blow and Banner (1962), pseudoampliapertura possesses a "smooth, non-granular wall" and usually achieves greater size than ampliapertura, which has a "rough, 'granular' and hispid wall". We attribute these differences mainly to the variable state of preservation of the material studied by Blow and Banner and to the fact that the large final chamber seen in the pseudoampliapertura holotype teneds to be smoother than the rest of the test surface. The ranges of the two supposed species are identical (e.g., Premoli Silva and Boersma, 1988) and other authors have experienced difficulty in separating them (e.g., Nishi and Chaproniere, 1994). Globigerina kondoi Todd, 1970, appears to be conspecific. PHYLOGENETIC RELATIONSHIPS.- Evolved from Turborotalia increbescens in the upper Eocene (Blow and Banner, 1962). STRATIGRAPHIC RANGE.- Upper Eocene Zone E 15 (Blow and Banner, 1962) to lower Oligocene. GEOGRAPHIC DISTRIBUTION.- Cosmopolitan, occurring across a broad range of latitudes. STABLE ISOTOPE PALEOBIOL0GY.- Poore and Matthews (1 984) recorded consistently light ō18O values for this species indicating a shallow-water habitat. Boersma and others (1987) recorded it (as T. pseudoampliapertura) with similar ratios to Subbotina gortanii. Pearson and others (2001) found variable isotopic values in their assemblages.
