TRIASSIC FISHES FROM SPITZBERGEN 
XIII 
Rhaetic stage .... Horizon with plant fossils. 
Noric » .... Horizon with Pseudomonotis spitzbergensis, Halobia cf. neu- 
mayeri, Spiriferina lundgreni etc. 
Karnic » .... Horizon with Lingula polaris , Halobia zitteli etc., Nathor- 
stites etc. 
Anisic » .... Daonella beds. 
(Muschelkalk) Fauna of Bivalves. 
Lower Saurian horizon. 
Horizon with Arctoceras costatum. 
Skytic stage .... Posidonomya beds. 
I have myself mentioned (Stensio, 1918b, p. 75) the occurrence of Triassic fishes 
in the bone-bed found by Salomon in 1910 (Stolley 1911, p. 115), which, as has already 
been pointed out, was formerly considered to belong to the Permian. Wiman’s assumption 
that at least certain of the strata between the Hustedia limestone and the fish horizon 
in the Ice Fjord region belonged to the Triassic has thus been shown to be correct. 
With regard to the fish fauna in the fish horizon I pointed out on the same occasion 
that on the whole its composition was of such a nature as rather to suggest lower 
Triassic age. 
When in 1910 Nathorst published his «Beitrage zur Geologie der Baren-Insel, 
Spitzbergens» etc. Triassic strata were known in the following regions in Spitzbergen. 
A) Ice Fjord region, comprising the south side and the inner end of Sassen Valley 
and the south side of Sassen Bay, the south part of Dickson Land, the field west of 
Ekman Bay between Cape Svea and Sefstroms glacier, a sweep of raised strata on the 
west side of the Ice Fjord extending down towards Bell Sound. 1 ) 
B) Bell Sound region. A sweep of raised strata on the north side of Van Mijens 
Bay, on the Mitterhuk and the south side of Van Keulen Bay at Reindeer Point and 
Cape Ahlstrand. 
C) Stor Fjord region comprising Stans Foreland (Edge Island), Barents Lands, the 
stretch of coast on the north side of the inner end of the Stor Fjord and on the peninsula 
between this end and the south part of the Hinlopen Strait. 
D) North East Land region comprising a part of the south-east corner of North 
East Land at the southern end of Hinlopen Strait. 
On the basis of material collected by Hoel and Rovig during the Norwegian 
expedition to Spitzbergen in 1917 I recorded in 1918 (Stensio, 1918b, pp. 75—77) the 
•occurrence of Triassic strata in the north-eastern corner of Horn Sound, and in this 
cases it seems evident that we have here a continuation of the Trias sweep at Bell 
Sound. 
Finally with regard to the relation between the Triassic series of Spitzbergen and 
other occurrences of Triassic I shall only give a very brief account. As we know, 
Mojsisovics (1886, pp. 147—153) grouped the Trias formations of Spitzbergen together 
I ) The geological map published by G. IDE Geer in 1910 is important for our knowledge of details 
■concerning this region.
