Fig. 10 in Hipparion macedonicum revisited: New data on evolution of hipparionine horses from the Late Miocene of Greece
Fig. 10. Body mass of Hipparion macedonicum from the various Greek localities calculated by various methods and its change in relation to the time. The body mass is estimated using the metapodials (Eisenmann and Sondaar 1998); W1. ln(body mass) = -5,768+3.011 x (lnMc10); W2. ln(body mass) = 3.151+2.665 x (lnMc13); W3. ln(body mass) = -4.525+1.434 x (ln(Mc10 x Mc13)); W4. ln(body mass) = -4.362+2.634 x (lnMt10); W5. ln(body mass) = -4.552+3.100 x (lnMt13); W6. ln(body mass) = -4.585+1.443 x (ln(Mt10 x Mt13)).

Fig. 8. Logarithmic ratio diagram comparing the RPl skull (A) and third metatarsal (B) with the Vallesian hipparions from Sinap, Turkey. Hipparion mediterraneum from Pikermi (Koufos 1987a) is used as standard of comparison. The metrical data for the Sinap material were provided to me by Raymond L. Bernor (unpublished material, personal communication, 2007).

Fig. 9 in Hipparion macedonicum revisited: New data on evolution of hipparionine horses from the Late Miocene of Greece
Fig. 9. Stratigraphic table indicating the distribution of Hipparion macedonicum in Europe. The geomagnetic time scale is from Cande and Kent (1995). The shaded area in the MN zones express the different opinions for the MN 12/13 boundary; according to Sen (1997) it is at ~7.0 Ma while according to Steininger et al. (1999) it is at ~6.6 Ma.

Fig. 4 in Hipparion macedonicum revisited: New data on evolution of hipparionine horses from the Late Miocene of Greece
Fig. 4. Principal component analysis of the skull (A), mandible (B), and third metatarsal (C) of the RPl small-sized hipparion in comparison with other small-sized forms of Eurasia, indicating its strong size-similarities with Hipparion macedonicum. As the available specimens are fragmentary, lacking measurements the mean cranial dimensions for each locality are used. The used variables (various measurements of the skull, mandible and MtIII) and their influence to the distinction of the specimens is given in the left part of the diagrams. The convex hulls indicate the allocation of the measurements in the space for its sample. Hipparion dietrichi, Hipparion mediterraneum, and Hipparion proboscideum or Hipparion cf. proboscideum are used as comparative samples.

Data from: New insights on equid locomotor evolution from the lumbar region of fossil horses
The specialization of equid limbs for cursoriality is a classic case of adaptive evolution, but the role of the axial skeleton in this famous transition is not well understood. Extant horses are extremely fast and efficient runners, which use a stiff-backed gallop with reduced bending of the lumbar region relative to other mammals. This study tests the hypothesis that stiff-backed running in horses evolved in response to evolutionary increases in body size by examining lumbar joint shape from a broad sample of fossil equids in a phylogenetic context. Lumbar joint shape scaling suggests that stability of the lumbar region does correlate with size through equid evolution. However, scaling effects were dampened in the posterior lumbar region, near the sacrum, which suggests strong selection for sagittal mobility in association with locomotor-respiratory coupling near the lumbosacral joint. I hypothesize that small-bodied fossil horses may have used a speed-dependent running gait, switching between stiff-backed and flex-backed galloping as speed increased.
