A large stalactite cave filled with prehistoric artifacts was discovered during work on a sewage line in Israel's Western Galilee region this week.

Construction crews immediately called in the Israel Antiquities Authority after unintentionally penetrating the previously undiscovered cave.

Archeologists said the cave is the richest prehistoric find in Israel in over 50 years, and contains numerous flint tools and the remains of animals that are now extinct in the region.

Over the coming months and years, researchers will carefully examine the cave and the artifacts found there to gain a better understanding life, climate and the animal population in the Land of Israel during the prehistoric periods.
