Having had some training in geology, that's a point I had wondered
about. It does seem that shorelines provide the best conditions for
fossilization. For an organism to become fossilized, it needs to be
covered with sediments before it decays or is destoyed by scavengers.
While an ocean or large lake shoreline might not be ideal, it should be
a whole bunch more condusive than open savannah.

Yet I remember this as an argument used by AAT supporters. The only two
possible reasons that come to mind are that those ancient shorelines
are now offshore and inaccessible, or that anthropologists have not
looked for hominid fossils along the ancient shorelines. Did I just
remember this wrong?
