Animals that die in a car (rod kill), animals that die in oil, dead animals that have died in zoos... What about these animals?
Some animal carcasses are used to study ecology, and they are also stuffed into the shape of a living thing and live a second life. The rod kill is made in a posture in which the wound is blocked even if the torso is cut or the wing collides with the windshield. The animal carcasses contaminated with crude oil should be washed and wiped clean to restore it to its original condition. You can observe closely the wild animals that are hard to see if you make them stuffed, and you can prove that animals exist on Earth if the animals are extinct. It is also possible to isolate the tissue from the stuffing and carry out genetic analysis if necessary, such as identification of the cause of the extinction.
