Scientists identify the forms as “constructions,” but they can’t figure out what they were for.
It was in 1990 when a French archaeologist first ventured deep into Bruniquel Cave in southwestern France. Spelunkers had just broken through the entrance, which apparently had been obstructed for millennia. The archaeologist traveled deep into the cave, over 1,000 feet.

The team found the circles of stone spikes, almost like 2-foot-high fences. …
