  1. aThe same specimen number is used for the associated remains of Macrauchenia patachonica found by Bravard
  2. bThe transverse processes are broken so they were probably slightly longer
  3. cIt was estimated from the most complete half
  4. dThe measurements were taken in a cast of MLP 12-1424, currently exhibited in a mounted skeleton in the MACN
  5. eThe transverse processes are broken in this specimen, but preparators added the missing areas which were included in the measurements.
  6. fThe Chillingham cattle is a relatively small-sized Bos taurus breed (Grigson, 1974).
