I found this in Belanglo Forest, very many apologies for the terrible photo, it was taken on my phone with my shaky hands. It looked like a pretty fresh kill but, after a good scout about I couldn't find even a scrap of fur left anywhere else. I'm thinking wallaby because of the toe arrangement, what do you think?
Found the remains of a domestic dog beside a quiet country road, ...it had been shot.
Rapid drying of the teeth after death cause long cracks to form.
There are three distinct types of vertebrae in this pic, from different parts of the same animal.
Yes, bone was contacted, I'm guessing a centre fire round like a .223 rem as there is a small entrance hole and
the back of the skull is badly damaged upon exit, not something you see with a lower powered .22 rimfire.
There was also a bone discoloured green from corroding copper, possibly the copper jacket from the bullet.
I'll try to take a pic and add it here.
edit .... and here it is, parts of the back of the skull.
