Animal found in mountain area, roughly (6)
I believe the answer is:
alpaca
'animal' is the definition.
(South American animal)
'mountain area roughly' is the wordplay.
'mountain' becomes 'alp' (the Alps are a mountain range).
'area' becomes 'a' (maths abbreviation).
'roughly' becomes 'ca' (abbreviation for circa).
'alp'+'a'+'ca'='ALPACA'
'found in' is the link.
(Other definitions for alpaca that I've seen before include "Break down (food)" , "South American animal" , "Llama relative, valued for it's wool" , "Wool of S American lama" , "South American relative of the llama" .)
