Research on subfossil lemur diets, particularly in southern and southwestern Madagascar, has indicated that ecological communities have been significantly affected by their recent extinction.[25] Many extinct subfossil lemurs were large-bodied leaf-eaters (folivores), seed predators, or both. Today, leaf-eating along with seed predation is only seen in mid-sized lemurs, and is far less common than it was in the past. Strict folivory is also less common, now found primarily in small lemurs.[8] In certain cases, subfossil lemurs, such as the sloth lemurs and koala lemurs, may have used leaves as an important fallback food, whereas other species, such as the monkey lemurs and the giant aye-aye, specialized on structurally defended resources, such as hard seeds and wood-boring insect larvae. Last, Pachylemur was primarily a fruit eater (frugivorous).[9] Subfossil lemur diets have been reconstructed using analytical tools, including techniques to compare tooth anatomy, structure, and wear; biogeochemistry (analysis of isotope levels, like carbon-13); and the dissection of fecal pellets associated with subfossil remains.[8
