Small Herbivores

[Mickey Megafauna]

Homalocephale Scale
Heterodontosaurus Unarmored Ornithopod Paleobotany
Lesothosaurus Unarmored Stegosaur Paleobotany
Microceratus Unarmored Ceratopsian Paleobotany
Pachycephalosaurus Scale
Protoceratops Armored Ceratopsian Paleobotany, only fights small carnivores
Scelidosaurus Armored Ankylosaur Paleobotany, only fights small carnivores
Thescleosaurus Unarmored Ornithopod Paleobotany, identical to Dryosaurus
Anymore? Hypsilophodon? More primitive ceratopsians?

 

[DragonNTiger]

Hetero, Lesotho and Microceratus are not Homalocephale scale... they're Compy scale; about half the size of Homalocephale or less. Homie sized animals would include Hypsilophodon, Leptoceratops, Minmi, and Orodromeus.

 

[TheMightyMegalosaurus]

Psittacosaurus sibiricus would work. It's the largest species of the genus and the tall rows of quills on its hips and tail would give it a distinct and noticeable feature.

 

[Stego0611]

what About Scutellosaurus, and Eoraptor, or Staurikosaurus or Nqwebasaurus.

 

[Archanubis]

Psittacosaurus sibiricus would work. It's the largest species of the genus and the tall rows of quills on its hips and tail would give it a distinct and noticeable feature.

It was also featured in the Jurassic Park: River Adventure rides at the Universal Studios parks, so it should hopefully be featured.

There's also Nanosaurus, which would be included due to the presence of Othnielia in the original novel (the latter is apparently now synonymous with the former).
