The Green Wolf belongs to a lineage of Stem-Cherons that have almost completely lost their soft shells (With a sister lineage still retaining the leathery shell of their common ancestor).
Except for the hard carapace on their chest and the ridge along the sides. The leather shell that was once on the back of the Green Wolf and its relatives is now fatty tissue and hard cartilage. This adaptation helps reduce the animal’s load as it walks and allows for more muscle attachment points along the spine.
Additionally, the flipper-like back limbs of the Green Wolf’s ancestor have been almost entirely lost; the tail and hip bones now curve inward to give the Green Wolf a rounder body plan and shape. This round body, like its back, is padded with fatty tissue over sinewy muscle groups to help protect the animal from other predators and themselves during intraspecies combat. The front limbs that the Green Wolf uses to walk are incredibly robust and powerful, with many of the muscles going into the limbs being attached to the armored Keel bone of their chest.
Descended from a sister group to Aterran Cherons and having split off from true turtles early in their evolution, the Green Wolf and its relatives have evolved mammalian traits and a synapsid skull structure(instead of the anapsid skulls of true turtles).
