Fossiler fra Smølen

Abstract

Forkortet: In the following the author describes a few fossils from a limestone of a some- what crystalline character from the island of Smøla. Fossils are very rarely found in this part of Norway, on account of the metamorphism that the rocks have undergone. The general geology of Smøla has recently been investigated by several Norwegian geologists, and two papers dealing with this subject - by J. Schetelig and H. Reusch: see p.3 - have been published of late. As regards fossils, only a few tiny fragments, - probably cystoid or crinoid stems besides a problematical Halysites and a single section of what is likely to be a gastropod, - have been found, the material being quite insufficient for any conclusions as to age. In the early part of the summer 1914, during a short visit paid to this occurrence of limestone for practical purposes, the author happened to find some fragments of silicified fossils weathered out on the surface of the rock, and on further treating some pieces of the limestone with hydrochloric acid, he succeeded in isolating the forms described below. Stromatopora sp. Fig.1 On the surface of the weatherworn limestone-rocks the cross section of large, slightly domed masses, with a prominent concentric structure were observed in several places.
