摘要：

Correlations between dental morphology and dietary preferences in ruminants explain the similarities but not the differences in relative incisor width encountered within the group. Observations on African browsing antelope have revealed extensive use of the lateral anterior dental elements for grooming purposes using a distinctive upward sweeping movement of the head. Inspection of these dental elements (I2, I3) and C) reveals a comb‐like array remarkably similar to the prosimian tooth‐comb. An hypothesis is presented to explain differences in incisor morphology based on the use of the teeth for purposes other than eating. The alternative biological role has implications for the use of dental characteristics in the determination of the feeding ecology of living and extinct ruminants. Copyright © 1990, Wiley Blackwell.
