Donating to the museum

In Wild World

"Woooo HOO! Simply splendid! I'm awash in delight! I must tell you a smidgen about the pachycephalosaur! This unique creature was one of the last dinosaurs to roam the earth, wot? Though it is known primarily for its rounded head... It was basically all bone! There was hardly a brain to speak of inside! These brain-boggling dinos never cease to amaze me! Hoo, so intriguing! Ah. My my! Terribly sorry. I babble... You must wonder if I've a brain in MY head!"

In City Folk

"...Hoo my! At long last, the pachycephalosaurus is complete! Hootie woo! The wonder of it all! Pachycephalosaurus roamed the earth right up until the end of the dinosaurs, wot? Its characteristic round skull boasted bone that was almost a foot thick... Quite thick indeed! But its head wasn't especially big...so it had little room for any brain..."

In New Leaf

After donating the final part of the fossil in New Leaf, its plaque in the museum will read:

"The pachycephalosaurus is known for its round, helmetlike head, the use of which is still debated. The bony dome atop its skull was nearly a foot thick, which is why mostly skull fossils survive. Some theories say the animals would smash their heads together to determine pecking order."

In New Horizons

"Pachycephalosaurus was, to be blunt, not the brightest star in the dinosaur firmament. What I mean is, with its incredibly thick skull, some 10 inches thick in spots, it didn't have much room for... well, for brains. Its brain was likely quite small, but at least it was extremely safe...in its...bony...prison."

Real-world information

Pachycephalosarus was a two legged ornithischian dinosaur that lived during the Late Cretaceous in what is now central North America. Its name, meaning "thick-headed lizard", comes from the 25 cm-thick dome on its skull. The most common hypothesis is that these domes were used for intraspecific combat, although this idea has its critics. Pachycephalosaurus is believed to have eaten leaves, seeds, and fruit, although its serrated front teeth suggest it may also have eaten some meat.
