In some ways, Kata Tjuta is even more fascinating than Uluru - the rocks do not consist of fine but hard sandstone like Uluru, but of a conglomerate of sandstone with embedded pebbles, so hard that, in many places, the pebbles are not freed from the sandstone by erosion but erode at the same rate, forming a surface as if cut by a giant stone knife. Imagine the rivers forming these pebbles eons ago, building up huge banks of them, which then converted into the rocks of Kata Tjuta! Even dinosaurs are relatively recent, compared with these rocks.
