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

 

Perspectives for Further Studies

The above literature data and discussion reveal the necessity of a revision of Upper Jurassic/Lower Cretaceous Dasycladales of the Northern Calcareous Alps. During a project funded by the Austrian Science Foundation (FWF Project "Jurassic/Cretaceous Carbonate Platforms"), the above mentioned occurrences will be studied in detail with respect to carbonate facies patterns, carbonate platform development and stratigraphy.

Concerning the calcareous algae, our studies will include: Systematics of calcareous algae, especially Dasycladales. Biostratigraphy, especially for the recognition of the Jurassic/Cretaceous boundary using Dasycladales, benthic foraminifera as well as complementary methods such as stable isotopes. Environmental reconstruction of the platform settings using calcareous algae. Paleo(bio)geographic implications of the dasycladalean distribution.
