化石食草动物常见于欧亚大陆、南北美洲和非洲，特别是在干旱和半干旱地区。 有充分的证据（尽管通常是间接和半定量的）表明它们对植被具有局部和大范围的影响。 这些影响来自摄食、收获和储藏、局部土壤扰动以及土壤结构和地形的长期变化，其中许多方面在化石食草动物的多样性中是相似的。 通常，这些动物活动的净效应是改变植物物种的组成并增加植物多样性。 植物的常备作物经常减少，生产力可能会发生长期和短期的变化。 需要更好地了解控制饮食选择和洞穴大小、动态和几何形状的规则，以预测这些动物在特定环境条件下的影响。
Fossorial herbivores are common in Eurasia, North and South America, and Africa, particularly in arid and semiarid regions. There is ample evidence, although often indirect and semiquantitative, that they have local and broad-scale effects on vegetation. These effects arise from feeding, harvesting, and caching, local soil disturbances, and longer-term changes in soil structure and topography, many aspects of which are similar among the diversity of fossorial herbivores. Often, the net effect of these animals' activities is alteration of composition of plant species and increased plant diversity. Standing crop of plants often is reduced, and long- and short-term changes in productivity can occur. Better understanding of the rules that govern diet selection and burrow size, dynamics, and geometry are needed to predict effects of these animals under specific environmental conditions.
