Just a thought

Try chaining them together. If that were absolute, many places
(e.g. drove roads and their stockyards) would be many feet deep
in bones from the millennia of debris.

Bones rot down in an active heap in between a few months and a few
years, depending on the size and age of the animal and whether the
bone was load-bearing. For example, the carcass and leg bones of
a chicken typically take 2 years, but the smaller bones disappear
within a year. The leg bones of a mature ox would probably take
the best part of 10 years, but lamb shanks take about 3-5.
