The diets of most subfossil lemurs, most notably Palaeopropithecus and Megaladapis, consisted primarily of C3 plants, which use a form of photosynthesis that results in higher water loss through transpiration. Other subfossil lemurs, such as Hadropithecus and Mesopropithecus, fed on CAM and C4 plants, which use more water-efficient forms of photosynthesis. Fruit and animal matter was more common in the diets of subfossil lemurs including Pachylemur, Archaeolemur, and the giant aye-aye. In southern and southwestern Madagascar, the subfossil lemurs of the spiny forests generally favored the C3 plants over the more abundant CAM plants, although closely related sympatric species may have fed upon the two types of plants in different ratios, allowing each to divide resources and coexist. Since plants produce defenses against leaf-eating animals, the extensive use of spines by plants in the spiny forests suggest that they evolved to cope with leaf-eating lemurs, large and smal
