酷東西

趣味知識

Tyrannomimus is the earliest known member of the Deinocheiridae family, a group of ostrich-like dinosaurs.2

Its name means 'tyrant mimic' because its hip bone looked like that of a tyrannosaur.1

Tyrannomimus lived about 121 to 113 million years ago during the Early Cretaceous period.5

Scientists found many bones of Tyrannomimus in the same quarry, suggesting several individuals died together.2

Tyrannomimus had a deep hollow in its skull called a tympanic recess, which helped make its head lighter.2

Its fossils were discovered in the Kitadani Formation in Japan, which also contained other dinosaurs like Fukuiraptor and Fukuisaurus.1
