Description A medium sized ceratopsian, Pentaceratops was about 6-7 meters (18-21) feet in length. It was similar in appearance to Chasmosaurus russeli, albeit with a larger skull and brow horns, and is likely synonymous with Titanoceratops ouranos, which was originally described as a large specimen of Pentaceratops to begin with. The name means Sternberg's Five-horned face, but this is misleading, as the "Five-horned" part comes from the epijugal bones, which look similar to another pair of horns. Like most chasmosaurines, it had only 3 horns. It lived in the late Cretaceous in the U.S, and was first found in the Kirtland Formation.

A personal favorite of mine!

Yeah! Marginocephalian dinofuzz! Great!

Β I like ornithopods with hair-like filaments!

Thanks! But did you mean ornithischians?

I mean the group of ceratopsians and pachycephalosaurs. But yes, it's plausible, that every ornithischian had hairy filaments, since we know, that heterodontosaurs had those filaments.

Really nice! However Titanoceratops and Pentaceratops can not be synonyms, or better, if they are synonyms then also Utahceratops, Arrhinoceratops, Coahuilaceratops, Bravoceratops and Anchiceratops would be incorporated in this synonymy for a matter of phylogenetic logic.

Thank you my friend! It would not surprise me if all of them became synonymous in the future, but Titanoceratops and Pentaceratops just seem way to similar to be considered different genuses. Granted, we have not found much of Pentaceratops in comparison to Titanoceratops, so I don't completely disagree about the possible differentiation. But scientists usually seem to jump the gun when it comes to dubbing new genuses of prehistoric fauna.

In a way, but if he tried using them as defense, it wouldn't work to well

The spines on the back look cool, they're almost like echidna spikesΒ
