Field study reveals six distinct bone weathering stages calibrated across known-age mammal carcasses, indicating that local environmental factors determine skeletal preservation timelines.

Key Points

To establish a standardized classification for mammalian bone weathering and calibrate degradation rates against time since death and local environmental variables.
Defined six descriptive stages of bone weathering based on macroscopic surface alteration.
Calibrated the progression and timing of weathering stages using known-age mammal carcasses in the Amboseli Basin, southern Kenya.
Evaluated the comparative influence of carcass body size, age class, and microenvironmental factors like temperature, humidity, and soil chemistry on degradation rates.
Most mammalian bones weathered and decomposed beyond recognition within 10 to 15 years of exposure.
Bones belonging to juveniles and animals under 100 kg weathered more rapidly than those of larger animals or adults.
Localized microenvironmental conditions, including humidity and soil chemistry, exerted a greater influence on weathering rates than regional macroclimatic factors.
