First evidence of Late Cretaceous decapod crustaceans from Åsen, southern Sweden

Sammanfattning: Decapod crustacean remains were uncovered in 2011 at Åsen, the first from this site. Åsens Late Creta-ceous strata are part of the Kristianstad Basin, in southernmost Sweden. Seven cheliped moulds and a number of other remains such as pereiopod imprints were found in carbonate-cemented nodules within the sediments of the Campanian B. balsvikensis zone. Several different morphologies are present, and three of the samples are interpret-ed as belonging to the family Callanassidae of infraorder Axiidea, with a probable association of Protocallianassa. The burrowing mode of life points to the conclusion that the nodules may be fossilized burrows, also explaining why they are constrained to a singular layer in the sequence.
