In Depth
Dating from the Bathonian period, Kileskus is even older than Guanlong making it a contender for one of the earliest tyrannosaurs. The partial skull remains have revealed the presence of a crest that rose up from the snout. Beyond this the only thing that can be said about Kileskus is that it appears to belong in a basal position of the Proceratosauridae, the group thought to belong alongside the earliest tyrannosaurs.
