Boudagher-Fadel et al. (1996):
Remarks: C. jurassica was designated as the
type and only species of his new genus Woletzina
by Fuchs (1973); his drawings are only doubtfully
of the same species as that described by Hofman
(1958), however. Hofman obtained her specimens
from the Bathonian-Early Callovian of SE Crimea
(Ukraine). The holotype of this species is lost
(personal communication, Dr Tatiana Gorbachik),
so we formally designate the paratype figured here
(Plate 2.7, Figs 11-13) as the neotype, following
article 75 of the ICZN (1985).
The neotype is high spired with four chambers
in the last whorl and an intraumbilical aperture
covered by a bulla (which has at least two accessory
apertures). The surface is covered with
pseudomuricae which occasionally fuse into very
short, disconnected ridges (Plate 2.8, Fig. 3). C.
dagestanica Morozova (the type species of
Conoglobigerina) also has a bulla (Plate 2.3, Fig.
10) and as noted above in our introductory section
('Origins') bullae are known from the first to last
Favusellacea. We have no hesitation in considering
Globigerina jurassica to be referable to
Conoglobigerina.
The specimens drawn by Fuchs (1973) came
from the Late Callovian and Early Oxfordian of
Poland and the intercameral sutures are more
deeply depressed than those of the neotype; their
identity is not yet proven. |
