Beyond the game
The real Hylaeosaurus
It was one of the three animals Richard Owen used to define Dinosauria in 1842. Despite that early discovery, only limited fossil material is known.
Gideon Mantell discovered it in 1832, among the first recognized dinosaurs. Being known since the beginning of paleontology does not mean having a complete skeleton today. Its historical importance and the amount of material preserved are two different things.
Ankylosaurs developed bony armor in their skin. Some lineages had a tail club and others did not; a club should not be added to every armored dinosaur.
