* "fossil" originally means "dug up" so the term references how the
specimen was found, not necessarily its condition or age. Any remains
that have been buried in substrate are fossils in terms of the original
definition. One way of defining the difference between "proper fossil"
and "subfossil" would be the state of the substrate - if it's still not
different from surface or currently-reworked soil/sediment, then
subfossil, if modified by mineralization/compression, then a proper fossil.
