Figure 2. Evolution of BM and GI-MT3 along the phylogeny for the studied species. Left: mean BM. Right: mean GI-MT3. Computations were made on the log-transformed cubic root of mean BM and the log-transformed GI-MT3. Values at nodes and along branches were reconstructed based on a Brownian Motion model of evolution (Revell, 2012). Colour codes for taxa follow Figure 1. Evolution of the third metatarsal shape depending on the GI-MT3 value is illustrated by specimens Hyrachyus eximius AMNH FM 12675 (minimum) and Teleoceras fossiger YPM VP 039358 (maximum).
