Xenoctopods are early branches off the terrathere tree and have 8 legs. Most of them live in a continent without xenotetrapods, but a few of them live happily with the xenotetrapods. |
Xenotetrapods are the main branch of terratheres, they are tetrapodal jawed terratheres. |
Nullmaians are jawless xenotetrapods, instead having the proboscis inside a pod-like mouth with an openable end. Because nullmaians don't have a jaw to crack open the armor of plants or animals they all need weapons. |
