The Devonian tetrapod-yielding localities of East Greenland are described
in detail, giving new information on distribution and stratigraphical
context. Three genera of tetrapods, Ichthyostega, Acanthostega and a third
not yet described, are known from different localities on Gauss Halvø and
Ymer Ø. On Ymer Ø, tetrapods have been found loose in talus on the north
and south sides of Celsius Bjerg. Tetrapod localities on Gauss Halvø are
distributed between Paralleldal and along the south coastline, and are
represented both by talus-derived and in situ collected material. One in
situ locality, yielding numerous Ichthyostega specimens, is located in the
lower part of the Britta Dal Formation on Sederholm Bjerg in Paralleldal.
An Acanthostega yielding in situ locality is located higher up in the
Britta Dal Formation on Stensiö Bjerg on the south coast. Talus-derived
material is reported from all areas and in both the Aina Dal Formation and
the younger Britta Dal Formation. A review and summary of the detailed
stratigraphy of the tetrapod-yielding succession on Gauss Halvø is
presented for the first time and is based on old literature, specimen data,
recent fieldwork, unpublished manuscripts and old field notes. Every
recorded locality has been put in this stratigraphical framework in order
to show a detailed distribution of specimens and enabling an assessment of
this distribution.
