both male and female of this species are the same in coloration.

Mantellisaurus, one of the bigger ornithopods compared to their small relative hypsilophodon. These animals can usually be found alone in the forest, grazing on low-lying plants, but they'll join larger herds roaming the plains every now and then. Due to their small size, they've taken on the run-and-flee tactic when it comes to escaping predators which has lessened the need for their thumb spike thus it has reduced in size. As for this species' vocalizations, they are one of the loudest animals on the island, with their calls being heard from up to miles. All this makes the Mantellisaurus an interesting dinosaur indeed.
