The Mountain Boomer is a small sized (by dinosaur standards) bipedal dinosaur evolved from a Thescelosaurus-like ornithopod.
Female Mountain Boomers are generally 6 to 7 feet tall while smaller males are usually 3 to 5 feet high. The males have a more vivid coloration than the females. The Mountain Boomer are found everywhere ... but tend to nest in the more remote mountain regions where they sleep lives in caves or burrows. Its is extremely fast, swift and agile, easily being able to outrun a human or other predator. Additionally, it has a tremendous leap. The creatures are shy and reclusive, fleeing as defence. They have a strange wolf-like howl.
