Working in the Arctic would not be possible without manifold support. Our sincere thanks go to the following people in Canada who helped to make our research a success: Sylvie LeBlanc (Department of Culture and Heritage, Iglooik, Canada); Jane Chisholm (Parks Canada, Iqaluit, Canada); John Innis (Universal Helicopters); the rangers of Parks Canada at Quttinirpaaq National Park (Ellesmere Island, Canada); the Polar Continental Shelf Programme team at Resolute (Cornwallis Island, Canada); Margaret Currie, Laura Smyk and Kieran Sheperd (all Canadian Museum of Nature, Ottawa, Canada). Alex Chavanne (California, USA) joined our team as an excellent field assistant, helped logging and sampling the Rollrock Section and found the giant Dorsoplanites specimen. Sarah Wallace-Jones (Sedgwick Museum, Department of Earth Sciences, University of Cambridge, UK) provided access to preparation labs. Magdalena Biszczuk (CASP) prepared the maps in Fig. 1; and Michael Pointon (CASP) polished the English. Ashton F. Embry (Geological Survey of Canada, Calgary) kindly shared his field observations and analytical results on the Rollrock Section. Mikhail Rogov (Geologicheskij Institut, Rossijskaja Akademija Nauk, Moscow) greatly helped by sharing expert knowledge regarding ammonites of the Jurassic-Cretaceous boundary interval and by providing literature. CASP's industry sponsors are acknowledged for funding the Canadian Arctic Islands Project. Peter Alsen (Geological Survey of Denmark and Greenland, Copenhagen, Denmark) and Terence Poulton (Natural Resources Canada, Calgary, Canada) provided careful and detailed reviews, which greatly improved the manuscript.
