Impoverished fossil association in the lowermost Sandbian of the Prague Basin (Czech Republic)

Abstrakt

The Darriwilian to the earliest Sandbian Dobrotivá Formation is a sedimentary unit in the Prague Basin (Czech Republic). It conformably overlies the Šárka Formation that formed during GOBE (Great Ordovician Biodiversification Event), during the rapid worldwide increase of faunal diversity.

The fauna in the Šárka Formation is rich and reflects the first of the two Ordovician diversity maxima observable in the Prague Basin. The character and diversity patterns of the faunas of both, the Šárka and Dobrotivá formations are similar in many aspects.
