Only one other time have I been able to offer an eremotherium calcaneus. This offering includes and astragalus and navicular. The preservation and color are very similar and they fit together very well. I can't say for sure they are associated, but the odds of finding these three bones that happen to fit together so well is not that likely. They are very heavy and solid with crisp articulating surfaces.

The calcaneus measures 11" across and the astragalus 6 1/2". All three bones weigh close to 11 pounds.
