Pre-Angkor Sculptures in "Thousands of Lingas /penis/"

Pre-Angkor Sculptures in "Thousands of Lingas /penis/" -- or Ling Poin in Khmer -- in "Phnom Kulen /litchee hill/" river bed which was the Cradle of [Khmer] Angkor Empire and Civilization.

You'll see Sculptures of Crocodiles -- among others, lingas included -- carved in the rocky walls and beds of the river, there. In proto-Khmer cultures, crocodiles are the very symbols of this nation's civilization as observed till now: the white-colored crocodile-flag -- called "the flag of soul" -- is erected at a funeral in commemoration to the dead person, according to the traditional ritual.
