The Centrosaurinae is a subfamily of ceratopsid dinosaurs named by paleontologist Lawrence Lambe, in 1915, with Centrosaurus as the type genus. The centrosaurines are further divided into two tribes, the centrosaurins and the pachyrhinosaurins.[1]
Classification
The below species were found to belong in Centrosaurinae by a 2014 publication (unless otherwise noted):[2]
- Centrosaurinae
The cladogram presented here follows a 2012 phylogenetic analysis by Ryan, Evans & Shepherd.[5] Clade names within Centrosaurinae follow Fiorillo & Tykoski (2012).[3]
Ceratopsidae |

This cladogram follows the phylogenetic analysis performed by Sampson et al. (2013). As is the case above, clade names within Centrosaurinae follow Fiorillo & Tykoski (2012).[3]

Possible neonate sized centrosaurine fossils have been documented in the scientific literature.[6] Research indicates that centrosaurines did not achieve fully developed mating signals until nearly fully grown.[7] Scott D. Sampson finds commonality between the slow growth of mating signals in centrosaurines and the extended adolescence of animals whose social structures are ranked hierarchies founded on age-related differences.[7] In these sorts of groups young males are typically sexually mature for several years before actually beginning to breed, when their mating signals are most fully developed.[8] Females, by contrast do not have such an extended adolescence.[8]-265" />
