Greek coin - Zeus ? [Resolvido]

5.75 g. - 17.70 mm

I see Zeus on the obverse but I don't recognize the subject on the revers. It looks like the head on an animal on the right and some parts look like wings (it could be upside down).

Can you help me to identify this coin?

Thanks a lot.

Bonsoir, 

Je pense qu'il faut tourner le revers de 180° 

et j'ai l'impression de distinguer un trident comme celle-ci:
