Sinotyrannus is a dinosaur confirmed to appear in Additional Creatures 2: Wild ARK.
Sinotyrannus, meaning "Chinese Tyrant", is a species of theropod dinosaur which lived in China during the Early Cretaceous, 120 million years ago. Sinotyrannus was a proceratosaur, a more primitive group of theropods closely related to tyrannosaurs. Sinotyrannus, at 9 meters long, was among the largest of them, being on par with its close cousin: Yutyrannus. It stands apart from Yutyrannus by the crest on its head, which was a common trait in proceratosaurs.
