Cenograms are used in studying ancient communities to draw conclusions about a biome's relative humidity.

Notes on verification

Multiple independent academic sources confirm cenograms (mammalian body-size distribution graphs) are used to reconstruct paleoenvironmental conditions, including relative humidity, vegetation density, and biome type. Some debate exists in the literature regarding the statistical robustness of climate correlations, but the core methodological claim is well corroborated.
