A therizinosaur track from the Lower Cantwell Formation (Upper
Cretaceous) of Denali National Park, Alaska.

We report on the first record of a therizinosaur from Alaska. This
record consists of a
single pes track from the lower part of the Upper Cretaceous Cantwell
Formation in
Denali National Park, Alaska, United States. This is the northernmost
occurrence for this
group of dinosaurs, and the presence of this animal in Alaska offers
the first support of
the proposed biogeographic model of faunal exchange during the
Cretaceous for these
unusual theropods.
