Draconyx loureiroi, "a new camptosauridae (Dinosauria, Ornithopoda) from the Late Jurassic of Lourinhã, Portugal Draconyx loureiroi, un nouveau camptosauridae (Dinosauria, Ornithopoda) du Jurassique supérieur de Lourinhã, Portugal"
 
"Draconyx (meaning "dragon claw") is a genus of dinosaur from the Late Jurassic. It was an ornithopod which lived in what is now Portugaland was a herbivore. It was found in the Lourinhã Formation in 1991, and described by Octávio Mateus and Miguel Telles Antunes in 2001.[1]"
 

Classification:

Ornithopoda is usually given the rank of Suborder, within the order Ornithischia. While ranked taxonomy has largely fallen out of favour among dinosaur paleontologists, some researchers have continued to employ such a classification, though sources have differed on what its rank should be. Benton (2004) placed it as an infraorder within the suborder Cerapoda (originally named as an unranked clade), while others, such as Ibiricu et al. 2010, have retained it at its traditional ranking of suborder.[7]
