00:03 Just off the coast of modern day Germany,
00:05 researchers have found a truly ancient discovery.
00:08 This is what they say is a prehistoric man-made stone
00:11 wall, one dating back more than 10 millennia.
00:14 It was discovered at a depth of around 69 feet.
00:17 But back when the structure was built,
00:18 it wasn't underwater at all.
00:20 The discovery was first made by geologist Jacob Gearson
00:23 while conducting underwater surveys with his students.
00:26 He returned a year later to confirm his suspicions,
00:29 this time with research divers and prehistoric experts.
00:32 They used echo sounding to reconstruct the area
00:35 during different periods, finding
00:36 that while the wall must be at least 8,500 years old,
00:39 as the area went underwater shortly after that time,
00:42 it's likely much older because of the wall's purpose.
00:45 Experts believe that it was likely built
00:47 to aid in the hunting of deer, as herds of the animals
00:49 will follow long, impeding structures.
00:51 Those include the likes of rivers or natural rock faces,
00:55 but also includes man-made walls as well.
00:57 And since reindeer left the area and headed north
00:59 upwards of 11,000 years ago, they
01:02 believe it must have been built before that.
