The documentation of enamel thickness variation across primates is important because enamel thickness has both taxonomic and functional relevance. The Old World monkeys commonly referred to as mangabeys have figured prominently in investigations of feeding ecology and enamel thickness. In this article, we report enamel thickness values for four mangabey taxa (Cercocebus atys, Cercocebus torquatus, Lophocebus aterrimus, and Lophocebus albigena), offer revised interpretation of the significance of thick enamel in papionin evolution, and place our new data in a broader comparative framework. Our data indicate that all mangabeys have thick enamel and that the values obtained for Cercocebus and Lophocebus equal or exceed those published for most extant non-human primates. In addition, new field data combined with a current reading of the dietary literature indicate that hard foods make up a portion of the diet of every mangabey species sampled to date. Clarification on the relationship between diet and enamel thickness among mangabeys is important not only because of recognition that mangabeys are not a natural group but also because of recent arguments that explain thick enamel as an evolved response to the seasonal consumption of hard foods.
描述灵长类动物釉质厚度变化的文献很重要，因为釉质厚度具有分类学和功能相关性。通常被称为山魈的旧世界猴在进食生态和釉质厚度的研究中占有重要地位。在本文中，我们报告了四种山魈分类群（白臀长尾猴、白臀叶猴、黑长尾猴和白眉猴）的釉质厚度值，重新解释了厚釉质在狒狒进化中的意义，并将我们的新数据置于更广泛的比较框架中。我们的数据表明，所有山魈都有厚釉质，而Cercocebus 和 Lophocebus 的值与大多数现生非人类灵长类动物公布的值相等或超过。此外，新的实地数据加上对饮食文献的当前解读表明，到目前为止，在对每一种取样的山魈物种的饮食中，硬食物都占一定比例。澄清山魈饮食与釉质厚度之间的关系不仅很重要，因为人们认识到山魈不是一个自然群体，而且因为最近有人认为，厚釉质是对季节性食用硬食物的一种进化反应。
