| Diagnosis / Definition: | ||||||
|
Pearson et al. (2006): DESCRIPTION. Type of wall: Microperforate, surface smooth to finely pustulose, pustules irregularly scattered on test surface. Test morphology: Test elongate, moderately tapering in initial portion, later parallel-sided, elliptical in cross-section; chambers biserial throughout, increasing gradually in size, slightly inflated, 14-16 in adult tests; sutures initially indistinct, later distinct and slightly depressed, nearly perpendicular to growth axis; aperture an elliptical opening at the terminus of the final chamber. Size: Holotype length 0.27 mm; paratype (USNM 689063) length 0.22 mm, width 0.90 mm, breadth 0.67 mm. |

Pearson et al. (2006): DISTINGUISHING FEATURES.- Differs from other Eocene zeauvigerinids by lacking a produced neck and lip surrounding the terminal aperture. It further differs from Z. zelandica by its more elongate test that parallel-sided for most of its length. DISCUSSION- The taxonomic position, stratigraphic distribution and phylogeny of this species are uncertain since the type material is not well preserved and it has only been recorded in New Zealand. PHYLOGENETIC RELATIONSHIPS.- Huber and Boersma (1994) suggested that Z. parri evolved from Z.zelandica during the early Eocene. STRATIGRAPHIC RANGE.- Lower Eocene Zone E7 to Zone E9; Heretaungan Stage through middle Eocene, Bortonian Stage in New Zealand (Jenkins, 1971). GEOGRAPHIC DISTRIBUTION.- Recorded at southern mid-latitudes sites, including New Zealand (Jenkins, 1971), DSDP Site 277 in the southwest Pacific (Jenkins, 1974) and DSDP Site 5 12 in the South Atlantic (Krasheninnikov and Basov, 1983). STABLE ISOTOPE PALEOBIOL0GY.- No data available. REPOSITORY.- Holotype deposited in the Geological and Nuclear Research Institute, Lower Hutt, New Zealand |
