Acristavus means 'crestless grandfather' because it is one of the oldest known duck-billed dinosaurs without a head crest.1
Its fossils were found in the Two Medicine Formation of Montana and the Wahweap Formation of Utah.5
Acristavus lived during the Campanian stage of the Late Cretaceous, about 83 to 72 million years ago.1
It belonged to a group called Brachylophosaurini, which includes other duck-billed dinosaurs like Brachylophosaurus.1
The type specimen, named MOR 1155, is a partial skeleton that helped scientists identify this species.5
Acristavus was a ground-dwelling herbivore that laid eggs, like all duck-billed dinosaurs.2

ຄຳຖາມທີ່ຖືກຖາມຫຼາຍທີ່ສຸດກ່ຽວກັບ Acristavus
?How big was Acristavus?
Scientists have not published a full size estimate yet, but as a hadrosaur it was probably around 8 to 9 metres (26 to 30 ft) long, about as long as a school bus.35

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