The first detailed reports of sauropterygian remains from the Arctic
island of Spitsbergen (Svalbard Archipelago) were published as short
notes in 1914 and 1916 by the eminent Swedish palaeontologist Carl
Wiman. Since then, his original specimens have languished in obscurity
despite recent discoveries renewing interest in the Scandinavian polar
territories as a highly significant source of Mesozoic marine amniote
fossils. A reassessment of Wiman's Spitsbergen collection housed in
the Museum of Evolution at Uppsala University, Sweden, has identified
a pistosaurid vertebral centrum from probable Upper Triassic (Carnian)
sediments in the Tschermakfjellet Formation, and various plesiosaurian
elements including a previously undocumented partial skeleton most
likely derived from the restricted Upper Jurassic (Tithonian) bone bed
of the Slottsmøya Member, Agardhfjellet Formation. Although
fragmentary, Wiman's sauropterygian fossils are historically important
and comprise one of the oldest stratigraphical occurrences from the
Mesozoic Boreal high-latitude region of Europe.
