... as transition from paleolithic to neolithic

in  http://emuseum.mnsu.edu/archaeology/sites/europe/franchthicave.html

    It is unique for having unbroken series
    of deposits spanning the period from ca. 20,000 B.C. down to ca.
    3000 B.C.

* no definite evidence of plant gathering before ca. 11,000 B.C.E.

* wild oats and wild barley -- neither becomes common until ca. 7000 B.C.E.

* The disappearance of the equid and caprine bones from the faunal
  assemblage, as well as an increase in the number of pistachios,
  all taking place ca. 8000 B.C. suggest a change of environment to
  open forests.
