How does this typically work?

[MysteriouslyMaple]

According to the Large Mythical Creature/Extinct Animal item, extinct animals can only get to about 10 feet; basically the size of horse to an elephant.

So since these creatures are smaller than 10 ft, I agree with Grimm Reaper's thoughts; to follow the height of modern day tigers but weighing much more than one.

I'd wait for staff confirmation though!!
