Classification: Chordata, Therapsida, Cynodontia, Haramiyida.
Species: K. jenkinsi (type).
Size: Unavailable due to lack of remains.
Known locations: Greenland - Fleming Fjord Formation.
Time period: Late Triassic.
Fossil representation: Partial dentary including premolar and molar teeth.
is a genus of cynodont
that lived in Greenland during the Triassic.
At the time of its description Kalaallitkigun is
known only from a
partial lower jaw bone and a premolar and molar tooth. The teeth
structure of the molar suggests that Kalaallitkigun
was intermediate in
its development lying somewhere between more primitive and more
advanced cynodonts. The molar of Kalaallitkigun
also suggests a
feeding strategy more akin to grinding, though it is unknown for
certain what Kalaallitkigun ate. The development
may suggests a
greater degree of herbivory, or at least been omnivorous, but
again, certainty is hard to establish.
