酷東西

趣味知識

Amtocephale may be the oldest known pachycephalosaurid dinosaur, living about 100 to 84 million years ago.2

Its name means 'Amtgai head' because the first fossil was found at a place called Amtgai in Mongolia.1

Only one nearly complete skull bone, called a frontoparietal dome, has been found so far.2

The dome of Amtocephale had deep pits on top, which helped attach strong neck muscles.2

Unlike some later dome-headed dinosaurs, Amtocephale did not have holes (supratemporal fenestrae) in the top of its skull.2

發現: Amtocephale was named in 2011 by paleontologists Mahito Watabe, Khishigjav Tsogtbaatar, and Robert Sullivan based on a single fossil dome found in the Baynshire Formation of Mongolia.5
仍有爭議: Scientists are not sure whether Amtocephale is the oldest pachycephalosaurid or just one of the earliest, because its skull features look like those of later, more advanced species.2
