- Jaws are part of an animal used for eating
- Teeth are part of an animal used for eating
- Hence, teeth and jaws are part of an animal used for eating

- Teeth have different shapes for eating different foods
- Jaws have different shapes for eating different foods
- Hence, teeth and jaws have different shapes for eating different foods

- Teeth and jaws are part of an animal used for eating
- Teeth and jaws have different shapes for eating different foods
- Therefore, animals that eat different foods have differently shaped teeth and jaws

- Carnivores only eat animals
- Herbivores only eat plants
- Therefore, carnivores only eat animals and herbivores only eat plants

- Animals that eat different foods have differently shaped teeth and jaws
- Carnivores only eat animals and herbivores only eat plants
- Therefore, canivores have differently shaped teeth and jaws than herbivores

- Canivores have differently shaped teeth and jaws than herbivores
- If one type of animal has a different feature compared to another type of animal, then that feature is specific to that type of animal
- So, certain teeth and jaws are specific to carnivores and other teeth and jaws are specific to herbivores

- Certain teeth and jaws are specific to carnivores and other teeth and jaws are specific to herbivores
- If a part of an animal is specific to a type of animal, then that part can be used to determine whether or not that animal was that type of animal
- So, teeth and jaws can be used to determine whether an animal is a carnivore or an herbivore

- Teeth are a part of an animal's skull
- Jaws are a part of an animal's skull
- Therefore, teeth and jaws are a part of an animal's skull

- Teeth and jaws can be used to determine whether an animal is a carnivore or an herbivore
- Teeth and jaws are a part of an animal's skull
- Hence, the skull of an animal can be used to determine if that animal was a carnivore or an herbivore

Therefore, the skull of an animal can be used to determine if that animal was a carnivore or an herbivore
