50,000 years is a pretty iffy radiocarbon date. Also the "tool" that's being displayed as evidence is so unsophisticated it looks pre-acheulean. On the other hand, maybe it is a tool, only not one made by Homo sapiens.

Yeah, the radiocarbon limit is only 60,000 years nowadays, but the age is also ballparked using its stratigraphy. I would like to know how ash remains are normed up for the test, since they might test older anyway having already been burned as they were deposited.
