Paleontologist Tony Fiorillo of the Museum of Nature and Science in Dallas, Texas, has been finding a lot of dinosaur action in Alaska.

In June, Ned Rozell reported on Fiorillo's Hadrosaur stone footprint found in the Wrangell Mountains. Most recently, Fiorillo and Thomas Adams have uncovered "trace fossils" belonging to the feather-clad cousin of the infamous Jurassic raptor in Denali National Park, Alaska.

The "trace fossils" belong to the "Therizinosaur," a less ferocious, fluffier dino when compared to the "Jurassic Park" celebrity varieties. According to

The Therizinosaurs were long-necked, pot-bellied omnivores and herbivores, albeit ones that had insanely long claws on their hands. They are some of the strangest dinosaurs ever found, and a track discovered in Alaska adds a few flourishes to our picture of the Therizinosaurs.

The new issue of "PALAIOS," an international journal of the Society for Sedimentary Geology, details Tony Fiorillo and Thomas Adams' discovery of the Therizinosaur's prints, which had never before been found in Alaska.
