Carbon and Oxygen Isotope Variation in Bivalves from Cretaceous and Paleocene of Seymour Island, Antarctica

Data include carbon and oxygen isotopic data from bivalves collected from the
late Cretaceous and Paleogene of Seymour Island. These include bulk sample
analyses averaging multiple years of growth for in individual specimens and
high resolution analyses for select bivalves resolving subannual seasonal
records.

Data are also included for belemnites and foraminifers present within the late
Cretaceous.

Minor element data are included for some, but not all specimens.

Genera and Species examined include: Cucullaea antarctica, Cucullaea ellioti,
Dozyia drygalskiana, Eselaevitrigonia regina, Lahillia larseni, and
Nordenskjoldia nordenskjoldi.
