128 POMPECKJ. JURASSIC FAUNA OF CAPE FLORA, [norw. pol. exp. 



The study of the fossils and rocks collected by Prof. Nansen, and the 

 critical examination of the fossils from the Jackson-Harmsworth Expedition, 

 described by Newton, give the following results with regard to the Jura oc- 

 curring below the basalt at Cape Flora. 



As far as the slight exposures of rocks in situ permitted of observation, 

 the Jura deposits of Cape Flora are composed of clay and slate-clay, inter- 

 stratified with hard sandy marl, beds of stone marl and clay-sandstone, with 

 "cone-in-cone", and phosphatic nodules, and thin layers of lignite and basalt. 



The lowest 1 fossiliferous beds correspond with the 



Bajocian, 

 and probably with the Lower Bajocian. At a height of from 23 to 33 feet 

 above the sea, to the north-west, only some 300 metres from Elmwood, 

 there occur gray, hard, sandy marls, and light gray, soft marl, in which 



were found: 



Lingula Beani Phill. 

 Discina reflexa Sow. sp. 



„ sp. indet. 

 Pseudomonotis Jacksoni n. sp. 

 Belemnites sp. (cf. BeyricM 0pp.) 



„ sp. (? Group of Canaliculati). 

 Numerous fragments of indeterminable Lamellibranchs. 

 The upper third of the sedimentary strata below the basalt — from 370 

 to 575 feet above the sea — contains deposits of the age of the 



Callovian 



and the three divisions of the Callovian are all recognisable, viz: 



the Lower Callovian 



(= zone of Macrocephalites macrocephalus, = zone of Cadoceras Elatmm). 



At a height of 370—450 feet above the sea, there occur clays which are 



partly phosphoritic, and contain scattered phosphatic nodules (south-western 



end of Windy Gully). The fossils of the Lower Callovian, some found in 



situ, some loose near the margin of the glacier north-west of Elmwood, are : 



1 The thin alternating estuarine strata of sand with carboniferous seams, about 100 m. 

 S. from Elmwood, possibly corresponding with the Cape Gertrude strata [cf. p. 12 (b), 

 Letter-press fig. 1, b and p. 32], are certainly older than the Bajocian beds with Lin- 

 gula Beani etc., but the true age, of these layers cannot be made out with certainty.
