This might be a double definition.

'resist' is the first definition.
(as in bucking a trend)

'horned creature' is the second definition.
'buck' can be an answer for 'creature' (buck is a kind of creature). I am unsure of the 'horned' bit.

Can you help me to learn more?

(Other definitions for buck that I've seen before include "Animal - dollar - responsibility" , "impetuous youth" , "vault" , "A slangy American dollar, may be fast" , "Blood < money" .)

I've seen this clue in The Times.
