Kileskus is a case study in the subtleties of theropod paleontology: technically, this middle Jurassic dinosaur is classified as a "tyrannosauroid" rather than a "tyrannosaurid," which means it almost, but didn't quite, belong to the exact same evolutionary line that went on to spawn monsters like Tyrannosaurus Rex. (In fact, Kileskus' closest relative seems to have been Proceratosaurus, which isn't recognized by most amateurs as a true tyrannosaur, though paleontologists might disagree.) However you choose to describe it, the (possibly feathered) Kileskus was clearly near the top of the food chain in its central Asian habitat, even if it was decidedly shrimpy compared to later tyrannosaurs.
