Recent paleontological fieldwork in the high Arctic archipelago of Svalbard, Norway reveals the presence of a rich assemblage of marine reptiles - plesiosaurs and ichthyosaurs. To date, approximately 60 individual skeletal occurrences have been mapped, of which 15 have been fully excavated. Individual skeletons range from partially to fully articulated, while bone preservation is variable and often dependent on factors relating to current permafrost conditions.
