Mars Rover Opportunity photo shows Dead Bird and Fossilized Horned Animal

An image taken by Mars rover Opportunity shows some interesting objects that looks like animals.

The first object appears to be a bird. The bird is so completely symmetrical that it is hard to tell that it was created by accidental natural forces.

The second object appears to be a horned animal, fossilized to stone. Clearly visible is its shape, head, open mouth, eye and horns.
