We're doing this?

Ok. Here's my take on the armour group.



I placed the Boneshark as the most basal in the group due to the lack of similarities with all other members.

Boneshark has 2 eye sockets, no hint of ever having had 4, a distinct head and neck, a feature no other member of the group shares, down-up tail motion, all other members aside from the Rockgrub seem to be adapted for left-right tail motion. And the Boneshark lacks true teeth, it just has serrations of the head plating whilst all other members have true teeth.

If I had my way the Rockgrub would be a million miles away from this group but Mr. Jubert has placed it here. Damnit Tom.

Oh also, Shinehorn, personally I would place the Arctic Ray with the Lily Paddler due to their very similar core body structure and eye stalks.
