The Gosau Group (German: Gosau Gruppe) is a geological stratigraphic group in Austria and western Slovakia whose strata date back to the Late Cretaceous to Eocene.[1] Dinosaur remains are among the fossils that have been recovered from the group.[2] It is divided into two subgroups, the Lower Gosau Subgroup which dates from 90-75 ma and the Upper Gosau Subgroup which dates from 83.5-50 ma, the sequence is largely marine, but the Grünbach Formation represents a terrestrial deposit.
