A hoplitinid-gastroplitinid ammonite assemblage in North Greenland - Linking the upper middle Albian in the Arctic with northwest Europe

An ammonite-rich horizon was discovered in an otherwise rather unfossiliferous Albian succession in Kilen, North Greenland. It contains an assemblage with both gastroplitinid representatives of the Arctic Province and hoplitinid representatives of the European Province. Correlation between those provinces has been hampered by very little faunal overlap. Hence, the assemblage discovered in Kilen provides a rare and unique occurrence of a mixed assemblage. It allows for the correlation of the upper middle Albian Euhoplites lautus Zone to a level with Pseudogastroplites in Kilen, North Greenland, and acts as a step stone for further correlation with the fauna in the Sverdrup Basin.
