Skeletal mount of Tyrannosaurus rex, copyright Scott Robert Anselmo.

Belongs within: Coelurosauria.

The Tyrannosauroidea are a clade of theropod dinosaurs known from the Late Jurassic and Cretaceous of Asia and North America including some of the largest of all carnivorous dinosaurs, as well as a number of smaller basal forms. Yutyrannus huali from the lower Cretaceous of China is the largest known dinosaur to preserve direct evidence of a covering of feathers (Xu et al. 2012).
