GREENLAND 52 5
The lower part of the Portland Sand (Albani Zone) is probably represented
by at least the upper part of the underlying Glauconitic Series
(total 50-80 m.), from which come various Pavloviae and a large ammonite
(originally 600 mm. in diameter) belonging to a many-whorled group
characteristic of the English Portland Sands, for which several of Buckman's
numerous generic names could be used. (Spath, 1936, p. 66,
assigns it to Behemoth.)
Dorsoplanitinae also occur in conglomerates on Kuhn Island and
Wollaston Foreland, with Stschurovskya (Maync, 1949, pp. 31, 98; Spath,
1947, p. 58).
UPPER KIMERIDGIAN (126 m.?)
The section in Milne Land (fig. 83) continues downward with 90 m.
of sandy clays and sandy micaceous marls, with nodules. In the (presumed)
upper part are numerous Pavloviae comparable with those in the Rotunda
and Pallasioides Zones, and in addition Dorsoplanites spp. Some of the
species continue up into the Glauconitic Series. In the (presumed)
lower part were collected six species of Pectinatites which correlate satisfactorily
with the Pectinatus Zone.
MIDDLE KIMERIDGIAN (86 m.?)
Below the Pectinatites beds come 86 m. of shales, said to be unfossiliferous
except for a thin band (50 m. up) of crushed Perisphinctids. These
are unidentifiable but have been tentatively assigned to Subplanites and
Sphinctoceras (Spath, 1936, pp. 13-17). An earlier record of Aulacostephanus
requires confirmation (ibid., p. 143).
LOWER KIMERIDGIAN (75 m.)
Next below in Milne Land come 75 m. of Amoebites Shales. In these
Spath (1935) recognized four successive ammonite horizons as follows:—
4. At top, oil-shales with Amoeboceras (Hoplocardioceras) decipiens
Spath, a deceptively Aspidoceras-like form with two rows of lateral tubercles,
figured also from Kuhn Island (Frebold, 1933, pi. i, figs. 1-4). It is known
only from Greenland.
3. Oil-shales with Amoeboceras (Euprionoceras) kochi, another large distinctive
subgenus, known only in Greenland and Spitsbergen. The
precise date of both horizons in terms of the European zonal scheme is
uncertain.
2. Shales with Rasenia borealis and various Amoeboceras. This is
dated to the Cymodoce Zone.
1. Shales with Rasenia orbignyi, R. inconstans and Amoeboceras spp.,
corresponding to the Baylei Zone. This assemblage is probably represented
also in Jameson Land.
Donovan states that in Traill Island and the northern area there are at
least 500 m. and 635 m. respectively of black shales, largely of Lower
Kimeridgian age.
