“So what did you call those things that were chasing you? Hairy-saurauses?”
“Herrerasaurus, from the Triassic era. Now that we’ve bred them we can easily classify them as early theropod.”
— Richard Kiley talking about Dilophosaurus on the tour.
Sinotyrannus (“Chinese Tyrant”) is a relative of tyrannosaurids that flourished in North America and Asia during the Jurassic and Early Cretaceous periods.
Sinotyrannus is known from a single incomplete fossil specimen including a partial skull, from the Early Cretaceous Jiufotang Formation of Liaoning, China.
Though it is not much younger than primitive tyrannosauroids such as Dilong, it is similar in size to later forms such as Tyrannosaurus.
It was much larger than contemporary tyrannosauroids; reaching a total estimated length of 9–10 m (30–33 ft), it is the largest known theropod from the Jiufotang Formation.
The original description of Sinotyrannus proposed that it could have been the earliest tyrannosaurid due to its large size, but subsequent analyses place it as a proceratosaurid tyrannosauroid.
It is considered to be part of a clade containing Juratyrant and Stokesosaurus, as they all reputedly share a narrow preacetabular notch.
A 2016 analysis instead placed Juratyrant and Stokesosaurus outside of proceratosauridae and proposed that Sinotyrannus is a sister taxon of Yutyrannus within proceratosauridae.
