546 INDEX TO THE STEATIGRAPHY OF NOETH AMERICA. 



Pseudomonotis suhdrcularis and probably comes from about the same horizon as this Cape 

 Thompson locality. These fossils were at that time identified as Aviculopecten and referred 

 to the Carboniferous, chiefly because of the stratigraphic relations they were supposed to hold 

 with well-characterized Carboniferous faunas. If Mr. Kindle's interpretation of the structure 

 is correct the horizon in question at Cape Thompson is above all the Carboniferous faunas 

 and offers no stratigraphic difficulties in its reference to the Triassic."

B 27. NORTHEAST COAST OF GREENLAND. 



The facts which are known regarding the Jurassic rocks of eastern Greenland 

 have been summarized by Skeat.''*^ According to the observations of the Danish 

 expedition of 1891-92, at Neill's Chffs there is a succession of strata which com- 

 prises the following : 



1. At the base a green sandstone, not found north of Cape Stewart. 



2. Next a gray sandy clay shale, with many fossil plants. This is seen in the valley, 160 

 to 180 feet above sea level, and also crops out immediately below on the shore. \ 



3. The next part of the slope is completely obscured by weathered fragments, which 

 conceal the underlying beds. 



4. Above is a very impure reddish-colored limestone, very rich in fossUs. The limestone 

 varies very considerably in different parts. It may be sandy and unfossiliferous; or full of 

 small pebbles sometimes roUed and sometimes angular, so that the rock is now a conglomerate 

 and now a breccia; lastly, it may be a typical shell breccia, crammed with fossils of Jurassic 

 age. These variations occur near each other and pass over into each other. The bed is 7 feet 

 thick and occurs at a beight of 186 feet above sea level. 



5. Above this is a sandy shale without fossils. 



6. Next comes a sheet of basalt 10 feet thick. 



7. This is overlain at the end of the valley by a yeUow sandstone, 6 feet thick, with a 

 few carbonized plant remains, which forms the uppermost deposit at Cape Stewart. 



Continuing along Hurry's Inlet, Neill's Cliffs get higher and higher, owing partly to the 

 position of the beds, but probably also to the fact that other beds crop out both above and 

 below those already mentioned. 



The members of the expedition landed toward the northern end of the inlet, approximately 

 southwest of the Fame Islands. Here the lowest bed exposed was a flaggy sandstone with, 

 once more, the fossiliferous limestone above. The limestone in this exposure is pure toward 

 the middle but conglomeratic or brecciated upward and downward. Not far but yet not 

 immediately above this limestone is the basalt again, which here appears at a height of 1,300 

 feet, with alternating layers of sandstone and dolerite above. Several beds which are seen here 

 belong to a higher horizon than those of Cape Stewart, and farther inland yet newer deposits 

 occur. The fossils obtained were mainly lamellibranchs and brachiopods; many were new 

 species, but certain typical Middle European forms, namely, Avicula munsteri cf. Goldf., Limea 

 dwplicata Sow., Ostrea sandalina cf. Goldf., were interspersed among them, the former in large 

 number. These species are of Middle Jurassic or Callovian age, and the fauna is altogether 

 characteristically Callovian; moreover it has close affinities with the Middle European type. 

 Lundgren, who examined the fossils collected on this occasion, identifies the Cape Stewart 

 beds with the Callovian of Kuhn Island; the lowest shales containing plant remains were 

 proved by Hartz to be of Rhsetic or Rhsetic-Lias age. 



The Swedish expedition of 1899 under Nathorst reports Rhsetic plant remains 

 and a yellow sandstone with numerous Ostreas and Belemnites. The map which 

 is published with Nathorst's work represents horizons of the Keuper, Rhsetic, 

 and Jurassic.
