Abstract
The material described and discussed in the present paper originates from a deep borehole near Slagelse on western Sealand. Quartzitic beds, probably belonging to the Mobergella holsti zone, are followed by silty shale with Lower Cambrian fossils. The fauna is represented by the following genera and species: Parahyolithes danicus n.g. et n.sp., Kjerulfia selandica n.sp., Holmia kjerulfi (Linnarsson)?, Ellipsostrenua conifrons n.sp., Torellella holmi Kiær, Torellella laevigata (Linnarsson), and indeterminable fragments of olenellid trilobites. The fossiliferous silty shale is referred to the Holmia kjerulfi zone. Finally, the eventual palaeogeographic significance of the material is discussed.
Highlights
As mentioned in the preface SoRGENFREI and BUCH (1964) referred about 390 m of the penetrated strata at Slagelse to the Lower Palaeozoic.The interval referred to the Ordovician-Silurian was classified by these authors partly by means of its graptolites
In material from the interval 2944----2966 m. the present writer succeeded in finding a few Lower Cambrian fossils which are described in the following in addition to brief descriptions of these strata and the subjacent quartzitic sandstone
Remarks: Kjerulfia selandica has several characters in common with the type species, Kjerulfia lata KIJER, for instance the pearshaped frontal lobe, the tiny tubercle on the posterior band of the occipital ring, the median depression connecting the occipital furrow with the preoccipital transglabellar furrow, and the long, strongly curved palpebral lobes; it differs from the type species in having narrow cephalic border, a notch in the posterior cephalic margin just inside the genal spines, much wider extraocular genal region, and frontal lobe much narrower than the adjacent portion of glabella
Summary
As mentioned in the preface SoRGENFREI and BUCH (1964) referred about 390 m of the penetrated strata at Slagelse to the Lower Palaeozoic. The interval referred to the Ordovician-Silurian was classified by these authors partly by means of its graptolites. This series of strata was characterized as follows: "25 83-29 J 7 111. Dark grey, beds of siltstone, light grey. It appears from this brief description that the interval 2583- 2812 111 ca n be referred safely to th e Silurian. The Diclyonema shale, is developed as alum shale; it is possible t!~a t part of the black shale may be of early Ordovician age. The present writer succeeded in finding a few Lower Cambrian fossils which are described in the following in addition to brief descriptions of these strata and the subjacent quartzitic sandstone In material from the interval 2944----2966 m. the present writer succeeded in finding a few Lower Cambrian fossils which are described in the following in addition to brief descriptions of these strata and the subjacent quartzitic sandstone
