Benthic macroinvertebrate associations from the Boreal Upper Jurassic of Milne Land, central East Greenland

Abstract

From the Upper Oxfordian to the Middle Volgian of Milne Land twenty-two marine benthic macroinvertebrate associations and ten assemblages are described. They occur in silici-dastic, shallow nearshore to offshore shelf sediments. Most of the associations are dominated by bivalves, some by brachiopods, and one by a serpulid polychaete. They are based on 135 samples containing close to 24 000 specimens. For each association, statistical data on faunal composition, trophic composition and life habits are given. The depositional environment of the Milne Land sequence is briefly discussed as are the faunal relationships with other parts of the Boreal Sea (North-East Greenland, Spitsbergen, and northern Siberia).
