Hypsilophodont

Hypsilophodonts are small, ornithiscians originating from the Early Cretaceous of Europe.

Characteristics
Hypsilophodonts are gracile animals, with a feathery coat covering their neck and back, large eyes compared to their body, and beaked mouths. They prefer the company of other herbivores, having been seen with herds of Stygimoloch and Triceratops in Vulture Valley and Psittacosaurus in New Fátima.

Destruction of the Collider
Hypsilophodonts were among the dinosaurs brought into Vulture Valley by the failure of the first USSR particle collider. A herd of Hypsilophodonts, alongside Stygimoloch, Triceratops, and Microraptors, were encountered by Vulture Squad and the Black Ops as they were traveling upriver towards the Russian Compound. All of the dinosaurs fled when a feeding frenzy of Kaprosuchus attacked them.

Arrival in New Fátima
Hypsilophodon were also among the dinosaurs brought over by a United States particle collider. A mixed herd of Hypsilophodon and Psittacosaurus were among the many dinosaur herds Stalker Force and their party encountered as they drove through the savannah. This herd was later attacked by a Carnotaurus, which mangled a Hypsilophodon with its horns. Another mixed herd was encountered after the party had been forced off a cliff by a Carcharodontosaurus known as The Goliath.

Trivia

 * It is never specified as to what genus of hypsilophodonts the animals in the first Primitive War are, and is not helped by the dubiousness of the clade itself.
