The Mono Spine Lizard, having somewhat of a spin places it as a somewhat close relative to the Gliding Spino-Lizard. Along with living in some of the habitats that the said Spino-Lizard lives, not in the water. However unlike it's cousin it is a more grassland hunter that seems to always live closer to grasslands next to open forests, loves to make a nest out of any fallen log it can gets it's claws on.  Like the other Dinosaur like creatures on Menagerie it lives on the same islands as the other Dinosaur like creatures, the Primal and Naturae Islands.
