Discovered in 2008 along the shores of the inland sea that once filled most of Utah, Talos sampsoni is an important troodontid dinosaur for paleontologists and paleoartists in that it confirmed what was speculated about in the 1960s with regard to limb morphology in these dinosaurs. Unlike the heavier-built dromaeosaurs, troodontids, and Talos in particular, had very long, thin legs, indicating it was a very quick runner, and also relatively short arms - these were definitely not gliders or climbers, but fast, active ground-dwelling hunters. Only one Talos specimen has been found, and it has a cracked, damaged sickle claw on its left foot, suggesting that just like in the dromaeosaurs, and unlike some of their smaller arboreal relatives, troodontids used that claw for combat.
