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.
