A bipedal lizard 2 meters long, with special characteristics that made it look somewhat freaky. Its mouth was toothless in general, although some species did have small sharp teeth to devour the new flowering plants that appeared for the first time in mid-Cretaceous. Its mouth closed with a strong peak like that of a parrot and hence the name Lizard Papagayo. A peak bone, a protuberance of the skull finished with keratin (like rhino horn) that provided a hardened tip and sharp as that of a parrot.
The other peculiarity of this animal is that its tail and back were covered with tubular and hollow bristles. One thinks bristles served as a peacock tail.
Walking on two hind legs, had tubular and hollow bristles as protofeathers, the parrot-like beak and normal ... now would wonder if it was related to birds. And the answer is NO. In fact, and this certainly surprise you, is related to the Triceratops or Eotriceratops. (Ceratopsia)
Animals heavy, clumsy, weighing several tons and with horns, one, three or even five. But if you look at the representations that have been made in the fossils found, we see that these large animals ... also have beaks.
