I like the cladogram but Ryan put Albertaceratops within Centrosaurinae, not as as sister-clade. So it should at least indicate the split with Chasmosaurinae to avoid ambiguity.--MWAK 07:55, 18 February 2007 (UTC)

That was my goof, so I adjusted it. J. Spencer 16:00, 18 February 2007 (UTC)

I'm having trouble finding authorities for the tribes within Centrosaurinae. TaxonSearch doesn't list either (though there is a Pachyrhinosaurinae). Mikko's site [1] lists Sampson 1995b for Pachyrhinosaurini but nothing for Centrosaurini. While the rule of coordination provides that these names do exist, we shouldn't use them here without something definite saying they have been used in print. Dinoguy2 06:00, 16 April 2007 (UTC)

"Pachyrhinosaurini" here is a self-redirect[edit]

The term Pachyrhinosaurini in this article currently redirects back to this article.
