As we wandered through a valley in a South-German forest, we stumbled across this skeleton:

A few key-facts:

• Big eyes
• It had two sharp "ear like" bones coming out of its skull
• The pictured remains were about 30-40cm long
  • Please mention the foot in the upper part of the image, which is ...
    • EU 45
    • GB 10,5
    • US 11,5

I don't have an idea what this might have been. Can anyone help out?

Edit:

As pointed out in the comments, the structure that is closer to the bottom end of the image could also be the pelvis bone and not the skull.
