Species Subbotina patagonica Todd & Kniker 1952 | ||||||
|
||||||
Diagnosis / Definition: | ||||||
Pearson et al. (2006): DESCRIPTION. Type of wall: Coarsely cancellate, sacculifer-type wall texture, normal perforate, spinose. Test morphology: Test very low trochospiral, globular, slightly lobulate in outline, chambers globular, embracing; in spiral view 3-3 1/2 globular, embracing chambers in ultimate whorl, increasing rapidly in size, sutures slightly depressed, straight, ultimate chamber large, about 1/2 the test size; in umbilical view 3-3 1/2 globular, embracing chambers, increasing rapidly in size, sutures slightly depressed, straight umbilicus very small, nearly closed, aperture umbilical, a rounded arch, bordered by a thickened rim that may display a lip, ultimate chamber large making up about 1/2 the test; in edge view chambers globular in shape, embracing. Size: Maximum diameter of holotype 0.32 mm, thickness 0.23 mm. |

Pearson et al. (2006): DISTINGUISHING FEATURES.- Subbotina patagonica is distinguished by its compact, low trochospiral test with 3-3 1/2 rapidly enlarging chambers, its arched, semicirculiar aperture and its coarsely cancellate sacculifer-type wall texture. DISCUSSION.- Blow (l979) regarded Subbotina patagonica as a cold water species (high latitude) that was related to Subbotina angiporoides. Indeed, the coarsely cancellate sacculifer-type wall texture and compact test links a group of subbotinids that has its origin in the Danian species Subbotina cancellata (Blow). Subbotina patagonica has not been widely recorded in stratigraphic studies, so that its geographic range is not well known. Its occurrence in the lower Eocene of the London Clay and in Trinidad suggests a widespread distribution. Bolli (1957) illustrated a morphotype from Zone P4 in the Lizard Springs Formation, Trinidad that he identified as Globigerina linaperta Finlay. This morphotype (USNM P5032), here illustrated in SEM for the first time (Plate 6.15, Figs. 12, 16), has a coarsely cancellate sacculifer-type wall texture and is referable to S. patagonica. Subbotina patagonica has not been widely recorded by workers, although it is possible that references to S. linaperta in the lower Eocene refer to this species. PHYLOGENETIC RELATIONSHIPS.- Subbotina patagonica is derived from S. cancellata (Blow) by an increase in the rate of chamber inflation and, in turn, gives rise to S. linaperta in the early Eocene. GEOGRAPHIC DISTRIBUTION.- There are two occurrences so far recorded in high latitudes locations of the southern hemisphere, and in other low-mid latitude locations. STABLE ISOTOPIC PALEOBIOL0GY.- Recorded by Boersma and others (1987) from DSDP Holes 525A and 548A with relatively positive ò18O indicating a deep planktonic habitat. This interpretation is supported by the boron isotope data of Pearson and Palmer (1999). |
