Which rock monolith is the largest in the world?

Mount Augustus is located in the Mount Augustus National Park in Western Australia. Mt Augustus is widely claimed in tourist promotional and information literature as the "world's largest monolith" but the claim does not originate from the geological literature, nor is substantiated by any other scholarly research. Mt. Augustus is more than twice the size of Uluru. Unlike Uluru, which is a monolith and, in general, devoid of plant growth, Mt. Augustus is a monocline.
