Fatgs divertents

1

Acristavus means 'crestless grandfather' because it is one of the oldest known duck-billed dinosaurs without a head crest.1

2

Its fossils were found in the Two Medicine Formation of Montana and the Wahweap Formation of Utah.5

3

Acristavus lived during the Campanian stage of the Late Cretaceous, about 83 to 72 million years ago.1

4

It belonged to a group called Brachylophosaurini, which includes other duck-billed dinosaurs like Brachylophosaurus.1

5

The type specimen, named MOR 1155, is a partial skeleton that helped scientists identify this species.5

6

Acristavus was a ground-dwelling herbivore that laid eggs, like all duck-billed dinosaurs.2

?Did Acristavus have a crest?

No. Acristavus is special because it had no crest or ornamentation on its skull, unlike most other duck-billed dinosaurs.34

?What did Acristavus eat?

Acristavus was a plant-eater (herbivore). It ate ferns, leaves and other plants that grew in its wet, seasonal habitat.53

Acristavus was named by Terry A. Gates, Jack Horner, and colleagues in 2011. The first fossils were found in Montana and Utah.1
Anc discutà
Scientists are not sure why Acristavus lacked a head crest while many other duck-billed dinosaurs had one.1
