BALTIC REGION 609 



The restoration in terms of original sedimentation, as I conceive it, is 

 shown in the second diagram (figure 8).

LOWER ORDOVICIC OF THE OHRISTIANIA REGION 



This region is nearer the meeting ground of the Atlantic and Siberian 

 faunas, and hence we find a more pronounced representation of both. 

 The section of the Ordovicic strata comprises the following: 



Super -formation — Etage 0. Siluric. 

 Ordovicic. 



Etage 5 b. With Meristella crassa. 



Hiatus and disconformity. 



Feet 

 Etage 5 a. Calcareous sandstone. 



5 a and b range from 150-370 



Etage 4. Shales and marls with Trinucleus, Chasmops, 



etcetera 700 



Etage 3 c X. Orthoelase limestone 8-13 



Etage 3 c £. Expansus shale 10-15 



Hiatus — disconformity. 



Etage 3 c a. Megalaspis limestone 3— i 



Etage 3 b. Phyllograptus shale 8-SO 



Etage 3 a X. Ceratopyge limestone 3-5 



Etage 3 a p. Ceratopyge shale 3-23 



Etage 3 a a. Symphysurus shale and limestone 1-20 



Hiatus — disconformity. 

 Upper Cambric. 



The Phyllograptus shale here represents the Planilimbata limestone. 

 It is followed by the limestones with Megalaspis limbata (3 c a), 4i and
