 "In Equus, how can you tell a cannon bone in the front leg from the back leg, and the
left from the right? When you hold the proximal (top) end of the cannon bone toward
you with the rounded side up, you will note that the proximal end of the metacarpal
(front leg) is oval in shape with the bottom flattened. The proximal end of the
metatarsal (hind leg) is larger and rounder. (See diagrams below.) Looking at the
proximal end of either the metacarpal or metatarsal, you will see that both will have
a small facet on them. If this facet is on the left side then the bone comes from a
left limb. If the small facet is on the right side then it's from a right limb."

I put two photos together and scanned them to make the image at left. The deposit
was within a few inches of the surface in a local area that was being developed from
being a meadow into a row of homes.
