When discovered in a cave on Gower in the 1820s the bones were thought to be around 18,000 years old, but were later redated to between 25,000 and 26,000... The skeleton of the Red Lady - actually a young male - was discovered at Goat's Hole Cave at Paviland on Gower in 1823 by William Buckland, then a geology professor at Oxford University... The remains were found along with a number of artefacts including ivory wands, bracelets and periwinkle shells... "Many of the bones were treated with preservations in the 19th Century and some of this contamination is often difficult to remove." He said their analysis was the bones were "just over" 29,000 years old."...and we really mean it this time. And she, I mean, he, was interred by loved ones in Sheep's Hole Cave, oops, I mean, Goat's Hole, oh, what's the difference?!?"
I guess they are certain, until the next “certain” determination...
