Höganäs Formation


The Höganäs Formation is a Late Triassic to Early Jurassic geologic formation in Skåne, Sweden. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.

Description

The Höganas Formation was deposited in what is now the southern part of Sweden Skåne. The formation straddles the Triassic-Jurassic boundary and has provided evidence of widespread mire-forest deterioration that began in the latest Rhaetian. The upper part of the Höganas Formation is correlated with the Rønne Formation of Bornholm, which is administered by Denmark. The Hóganas Formation is rich in coal and has provided many fossil flora.

Ichnofossils

Tracks discovered in the Höganäs Formation have been assigned to the ichnogenus Grallator cf. giganteus, which were discovered in Rhaetian strata, and Grallator soltykovensis, which were discovered in Hettangian strata. A few of the tracks were taken to museums, but most of them disappeared in natural floodings. In 1994, Gierlinski and Ahlberg assigned these tracks from the Hoganas Formation of Sweden to Dilophosaurus as well.
