Fossiliferous Lower Cambrian at Äspelund on the Skäggenäs Peninsula

An abundantly fossiliferous Lower Cambrian locality has been discovered at äspelund, parish of Ryssby, Småland, in the western part of the Skäggenäs Peninsula. The sequence, exposed in a water well, consists of a few thick and a number of thinner sandstone beds alternating with grey and reddish shale. Current ripples and trails occur, and there is a conglomerate with well rounded Precambrian quarzite pebbles in one of the sandstone beds. The fauna consists of the brachiopod Micromitra undosa (Moberg) and the problematic disk-like-fossil Mobergella holsti (Moberg) which occurs together with hyolithelloid tubes. New figures of these fossils are given. A lectotype is designated for Mobergella holsti.
