@HellWolf Those are not Wyvern attributes. A wyvern in its truest form is one such as Rathalos, a bipedal, winged monster without forearms, with a long tail and theropod-like gait. Only subclass that gets away with this are Pseudowyverns, as they have most of the qualifications, but walk a little differently. Technically, Giant Wyverns (Or at least Ukanlos or Odeibatorasu, which have absolutely no wings whatsoever) should not rightfully be classified as Wyverns, and nor should Brute wyverns, or Raptorial Bird Wyverns for that matter.

Zinogre is pretty much just a big dog monster. It's much closer to being a fanged beast than a Wyvern of any sort. That list of attributes you gave is very vague and highly general, and could be applied to an infinite number of non-wyvern designs.
