Classification: Chordata, Reptilia, Dinosauria, Saurischia, Theropoda, Troodontidae.
Species: T. sampsoni (type).
Size: Roughly estimated at about 2 meters long.
Known locations: USA, Utah - Kaiparowits Formation.
Time period: Campanian of the Cretaceous.
Fossil representation: Partial post cranial remains including rear limbs, partial pelvis, vertebrae and a forelimb bone.
is so far only known from a partial post cranial skeleton that is
mostly represented by the rear limbs. However when these remains are
scaled to the same proportions as other more complete troodontid
genera, a rough estimate of around two meters in length can be
attained for the animal. Like other troodonts

Talos is the first genus of troodontid dinosaur recovered from the Kaiparowits Formation of Utah. Other theropods known from this formation at this time include oviraptosaurs and probable ornithomimosaurs, though the principal predatory threat would have still belonged to tyrannosaurs, with the mid-sized genus Teratophoneus also known, as well as isolated but not so well preserved remains of even larger tyrannosaurs.
A little bit further South in the Campanian aged Wahweap Formation, another tyrannosaur named Lythronax was roaming around at the same time as Talos, and it’s not wholly inconceivable that the two may have crossed paths since living animals would not have been confined to current fossil locations.
