Abstract

Vertebrate micro-remains of jawless vertebrates (psammosteid heterostracans) and gnathostomes (acanthodians and sarcopterygians) occur in a residue collected from the Late Devonian Kap Graah Group sandstones of East Greenland. Fragmentary and isolated elements of psammosteids are assigned to Psammosteus sp. The acanthodians are represented by scales of acanthodiform type and poorly preserved fin spines. Tooth and scale fragments of sarcopterygians may suggest a porolepiform affinity. This assemblage and the associated macro-vertebrate fauna indicate a Frasnian age for anotherwise assumed Famennian part of the East Greenland succession, and do rather effectively bracket the Frasnian–Famennian boundary.
