Lurdusaurus is a large herbivorous ornithopod. Lurdusaurus is unique among ornithopods for its stout build and relatively short limbs, giving it an uncanny resemblance to the ankylosaurs despite not being a direct relative. This short, stout build is thought to have served a similar purpose as it does in the hippopotamus, allowing the creature to move on both land and in the water.
The Lurdusaurus in the game will be the first semi-aquatic herbivore, comfortable on land and in the water, but not masters of moving on either. This allows the Lurdusaurus to use the water to escape the predators of the land, and land to escape aquatic predators. This means that the Ichthyovenator is currently the prime candidate for Lurdusaurus' main predator, since it can easily follow no matter where Lurdusaurus tries to go.
Other facts: While currently not in the game, the Lurdusaurus will be in the EA release.
