Talos

Name: Talos ‭(‬After a giant bronze automaton from Greek Mythology‭)‬.
Phonetic: Tay-los.
Named By: Lindsay E.‭ ‬Zanno,‭ ‬David J.‭ ‬Varricchio,‭ ‬Patrick M.‭ ‬O'Connor,‭ ‬Alan L.‭ ‬Titus‭ & ‬Michael J.‭ ‬Knell‭ ‬-‭ ‬2011.
Classification: Chordata,‭ ‬Reptilia,‭ ‬Dinosauria,‭ ‬Saurischia,‭ ‬Theropoda,‭ ‬Troodontidae.
Species: T.‭ ‬sampsoni‭ (‬type‭)‬.
Diet: Carnivore.
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.

       Talos 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 and earlier dromaeosaurs,‭ ‬Talos had an enlarged sickle shaped killing claw on each foot.
       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.
