Tylocephale

名字的意思： “swollen head”1

吃：植物腫頭龍類白堊紀晚期

Tylocephale was a small, dome-headed dinosaur that lived in what is now Mongolia. It walked on two legs and used its thick, bony skull for head-butting fights. This plant-eater had a strange, swollen head that made it look like a tiny, feathered battering ram.1 2

趣味知識

Tylocephale's skull dome was highest at the very back, near the neck, which is different from other dome-headed dinosaurs.2

Its name means 'swollen head' because of the thick, bony bump on top of its skull.1

Tylocephale lived about 72 to 71 million years ago, during the Late Cretaceous period.1

The only known fossil of Tylocephale is a partial skull and jaw, found in 1971 by a Polish-Mongolian expedition.1

Tylocephale shared its home with other dinosaurs like the armored ankylosaurs Tarchia and Saichania, and the horned ceratopsid Breviceratops.1

Scientists think Tylocephale may have used its dome for head-butting fights, like modern bighorn sheep, but this is still debated.2
