Dilong paradoxus (Xu et al., 2004 TNP01109) Early Cretaceous ~125 mya, 2.75 m in length, was derived from a sister to Guanlong at the base of the Deinocheirus + Guanlong clade. This clade includes megaraptors and spinosaurs, no tyrannosaurs (contra Xu et al. 2004).

Dilong was covered with feathers or protofeathers. The original skull drawings are misleading and do not reflect the fossil skull above.

Murusraptor barrosaensis  (Coria and Currie 2016; Rolando, Novas and Agnolin 2019; Late Cretaceous) was originally considered a sister to Megaraptor and close to tyrannosaurs. Here it nests between Dilong and Guanlong closer to spinosaurs.
