A zoologist analyzes the jawbones of an extinct mammal and concludes that it was an herbivore. The zoologist most likely came to this conclusion based on the shape of the teeth.

Animals that consume plants, such as deer, elephants, cows, and many others, are known as herbivores. They eat a range of vegetables, fruits, grasses, grains, and other foods depending on the habitat of the specific animal, hence they are essentially vegetarians.

The broad, flat teeth of herbivores are perfect for chopping up the plant material they consume. These animals' teeth enable them to break down the fibers in their food, making it much simpler for them to digest.

Plant-eating animals known as herbivores have large, flat molars and sharp incisors. They don't own any dogs. The incisors, canines, and molars of omnivores are used for a range of foods. The teeth of herbivores are designed to crush and ground vegetation.
