CONCLUSIONS 



The fauna under consideration is made up mainly of trilobites and, to a minor extent, 

 of brachiopods. No representatives of other classes of animals have been met with. Agnostidae 

 and Anomocare excavatwn are the most common forms. A characteristic of the fauna is that 

 the specimens generally are of minute size. From this fact it cannot be concluded, however, 

 that the fauna lived under imfavourable conditions which impeded its full development, 

 as solitary specimens of Anomocare excacatum and Agnostus glandiformis attain the size 

 of full-grown Scandinavian specimens. 



Ten species, all trilobites, have been determined generically and specifically. A few 

 more species of trilobites and at least four species of brachiopods are present, but as they 

 are represented by very incomplete fragments only — in some cases, moreover, these are 

 fragments of immature specimens — their references cannot be safely decided at present.
