Define selenodont teeth and identify the mammal group in which they are common.

Explanation:
Selenodont teeth are defined by crescent-shaped enamel ridges on the grinding surfaces of the molars, tuned for shearing and grinding fibrous plant material as the jaws move. This pattern is a classic feature of ruminants, including animals like cows, sheep, goats, and deer, so the description fits them best. The other patterns describe different dentitions: low-crowned, rounded cusps point to bunodont teeth typical of omnivores; ridges that run across the tooth describe lophodont dentition; and high-crowned teeth refer to hypsodont dentition related to tooth height rather than the crescent ridge pattern.
