Early Cenomanian (100.5–95.7 Ma) ammonite faunas from East and North-East Greenland collected by the late Simon Kelly and colleagues are described. The assemblages are dominated by typically boreal Schloenbachia varians (J. Sowerby 1817). Also present are Parapuzosia (Austiniceras) austeni (Sharpe 1855) and species of more typically Tethyan genera. These include Phylloceras (Hypophylloceras) lombardense (Joly 2000), Gaudryceras (Gaudryceras) cassisianum (d’Orbigny 1850), Gaudryceras (Mesogaudryceras) leptonema (Sharpe 1855), and the hypermorphic tetragonitine Titanoleioceras boreale gen. et sp. nov. Previously known only from Geographical Society Ø and Traill Ø, the newly described material extends the distribution of these early Cenomanian faunas northwards to Hold with Hope and south to the Kangerlussuaq Basin. The phylloceratids, gaudryceratids, and tetragonitids in these assemblages are probably not preserved in their preferred original habitats, but rather drifted to their respective sites of burial ...
