74. ........but maybe it's a goner - as it did threw stones(6) I have the answer as an anagram of words 4 & 5. Not sure where the throwing stones comes in though.
I had to look it up as I had never heard of the animal (the anagram you referred to) and found another definition for that word: a military machine that "threw stones", a type of historical catapult.
