Early descriptions of Norwegian trilobites. The type specimens of C.Boeck, M. Sars and M. Esmark.
1, 2

The main scope of the present paper has been to illustrate a number of trilobite species described by Norwegian authors more than one hundred years ago. The early descriptions are generally very brief and incomplete and are rarely accompanied by good illustrations. It has therefore been difficult to distinguish the specific characters of many important trilobite species occurring in the Cambro. Silurian strata of Scandinavia. In the old collections or the Paleontological Museum it has, however, been possible to find most of the original specimens and from among those the types have been selected. The types are presented in untouched photographs and the reprinted original descriptions are commented upon. A brief historical review of the early paleontological studies in Norway is also given.
