About
Centrosaurinae is one of two groups of dinosaurs within ceratopsidae, the four-legged leaf-munchers affectionately known as "horn faces".
Compared to chasmosaurines (the other group of ceratopsids), centrosaurines have shorter frills, shorter deeper snouts, and at least one pair of spikes or hooks coming off the top of their frill. The latter were once easily distinguished from the former by the prescence of a longer nose horn or bony boss and shorter brow horns, but the trend-bucking Albertaceratops, Diabloceratops and others put paid to that.
Centrosaurines are known almost exclusively from the Campanian-Maastrichtian of North America, and many sport outrageously flambuoyant head decor. But Styracosaurus is their king of facial bling, having more spikes and prongs than you could shake a stick at.
Some palaeontologists split Centrosaurinae into two tribes: the centrosaurins and the pachyrhinosaurins.

Etymology
Centrosaurinae is derived from the Greek "kentron" (spur, sharp point or prickle), "sauros" (lizard) and "inae" (sub family), and is named for the group anchor, Centrosaurus.
