Evidence of a lower dance score (4,4)

I believe the answer is:

hoof mark

'evidence of a lower' is the definition.
(eg mark left by a cow, animal which moos or lows)

'dance score' is the wordplay.
'dance' becomes 'hoof' (hoof can mean to dance).
'score' becomes 'mark' (synonyms).
'hoof'+'mark'='HOOF-MARK'

I've seen this clue in The Guardian.
