Upper Jurassic to Lower Cretaceous Dasycladales of the Northern Calcareous Alps: the state of knowledge

Relevance of Dasycladales Algae

The Late Jurassic to Early Cretaceous represents a time interval of considerable increase of Dasycladales compared to the Early and Middle Jurassic as well as a considerable generic renewal.

In the Northern Calcareous Alps they are of great importance, because they

(1) allow paleobiogeographical reconstructions of these newly formed carbonate platforms,

(2) provide a basic tool for the paleoecological interpretations of the platform settings,

(3) represent a biostratigraphic tool for recognition of the Jurassic/Cretaceous boundary.
