Now is this because LAGs are not annual, or is it because old lags near the
center of some bones are being eroded away by bone remodelling (a bit like
stratigraphy-beware of unconformities). If the latter is the case then the
situation wouldn't be hopeless, you would just have to take care in which
bone is used and to look out for signs of erosion of the old LAGs.
