Tyrannosauroid /
coelurosaur origins: a new species from the late Jurassic of China,
Guanlong wucaii
Xu
et al. 2006, represents an early stage of tyrannosauroid development.
It is a rather primitive coelurosaur,
maybe related to
Proceratosaurus
.
Bearing a little distal
foot, its ischium is similar to that of
Allosaurus
