High resolution trilobite stratigraphy of the Lower–Middle Ordovician Öland Series of Baltoscandia

Geological Magazine, 2012
AbstractThe first ever list of the regional Öland Series (Tremadocian to mid Darriwilian) trilobites and agnostids from the whole of Baltoscandia is compiled. The study includes revision of systematics as well as vertical and horizontal distribution. This is necessary because of the uneven state of knowledge, some faunas having being studied recently ...
