We don't know what the definition of the class "Fanged Wyvern" is, so we don't know. Many people speculate that they are a link between (Pseudo-)wyverns and Pelagi, what Zinogres fur and wolf-like behavior suggest. Though until there's another member of Fanged Wyvern but the two Zinogre subspecies or Capcom defines them completely (maybe they did already and we couldn't read it in MHP3rd?) we can't say.
