Proceratosauridae

Yutyrannus (meaning "feathered tyrant") is a genus of proceratosaurid tyrannosauroid dinosaur which contains a single known species, Yutyrannus huali. This species lived during the early Cretaceous period in what is now northeastern China. Three fossils of Yutyrannus huali — all found in the rock beds of Liaoning Province — are the largest-known dinosaur specimens that preserve direct evidence of feathers.

Guanlong () is an extinct genus of proceratosaurid tyrannosauroid dinosaur from the Late Jurassic (Oxfordian) Shishugou Formation of China.

Two individuals are currently known, consisting of a partially complete adult and a nearly complete juvenile.

Proceratosaurus ( ) is a genus of theropod dinosaur that lived during the Middle Jurassic in what is now England. The holotype and only known specimen consists of a mostly complete skull with an accompanying lower jaw and a bone, found near Minchinhampton, a town in Gloucestershire. It was originally described in 1910 as a species of Megalosaurus, M. bradleyi, but was moved to its own genus, Proceratosaurus, in 1926. The genus was named for its supposed close relationship with Ceratosaurus, later shown to be erroneous, due to perceived resemblance of Proceratosaurus incomplete cranial cre
