Dinosaurs and Their Noses A few questions. First, anyone out
there know (or have an idea) why centrosaurine ceratopsids
(ceratopsians, aka, horned dinosaurs) had those anteriorly-
pointing nasal prongs, formed from the maxilla and nasal bones?
I sure don't. And why didn't chasmosaurines have them? Also, how
does the pachyrhinosaur's nasal boss develops from something
like *Einiosaurus'* well developed horn into something like
*Achelousaurus'* boss? The boss was porous, but the horn not
nearly so, and while I gather that the porousness of the bone
could increase and deform the original shape, why? Finishing my
