Here's some non-shock gore references, this means that there's no mutilation, severe injuries, etc.
BUT this is still dead animals and real gore, something not everyone can handle.
All of these photos are taken from my personal dissections and diggings. As I work on each animal, I have my own process to lay them to rest, whether I keep their remains afterwards or not.

Feel free to trace these, reference them, paint over, use as studies, anything you might need them for. You do not need to credit me if you use them!
