Thanks everyone! I hope you will like this new format, because I will use this for next drawings! But not only dinosaurs and local fauna. The journal have many pages related with factions, weapons, locations and beigns from other realities.
@Adon: Yes, my first name is like the hunter from Jurassic Park 2, most people said me that xD.
@Duke64: The funny thing about ceratopsians (Family of Triceratops, Styracosaurus) have many theories about the use of horns. One said if it was defensive, the design would standarized like theropod dinosaurs.With this, the horns and frill were used to attract females. But I think was a mix of defensive and offensive. About the broken horn, probably was broken in a battle or by an accident. The thing is animals are like us, we are different. Probably one ngoubou have the second nasal horn bigger than the first, or have smaller horns in the frill.
