coyotes

— have carnassial teeth

didelphis, chimp, human

species with compression teeth (3)

chinese water deer, longhorn, beaver

species with grinding teeth (3)

hypsodont

chinese water deer, longhorn, and beaver have — teeth

bunodont

chimps and humans have — teeth

beavers

— have specialized incisors

cartilage

the shark has a — jaw

homodont

all the teeth in the jaw have the same general size and shape

heterodont

 the teeth in the jaw have distinctly different shapes and sizes

diphyodont

 the teeth in the jaw are replaced once during life. This is seen in mammals that possess a set of milk teeth and then replace those with the adult teeth

polyphyodont

teeth are replaced continually throughout life

acrodont

teeth are attached to the dorsal surface of the jaw without sockets

pleurodont

teeth are attached to the medial surface of the jawbones (often the dentary)

thecodont

teeth are set in bony sockets

incisors

tooth specialized to bite and cut

• clip pieces off of food

canines

teeth specialized to grab and rip

• capture and combat

molars

teeth specialized to grind and tear

• mastication and mechanical digestion

carnassials

the last premolar of the upper jaw and first molar on lower jaw of true carnivores

• They work like scissors to shear

compression teeth

— work like a mortar and pestle to break up hard substances. They can be found on the jaws of many mammals that are omnivores or have a diet of berries and nuts. These teeth tend to be relatively shorter, low-crowned, or brachydont.

Brachydont

— teeth are a type of tooth characterized by having:

• Low crowns (short height)

• Well-developed roots

• Narrow enamel coverage that does not extend far below the gum line

Grinding

— teeth are found most often in animals that feed on mostly plant material
