A/Prof Malcolm Wallace says he loved fossils as a child, and wanted to become a palaeontologist. He also liked rocks, however, and at university chose geology. He has brought these interests together for of one of the most significant fossil discoveries in Australian history. If he's right, this may soon lead to something even bigger.rnWallace was part of the discovery of an enormous reef at Arkaroola in the Flinders Ranges. The reef is ten times the size of something you would find on the Great Barrier Reef, and has been dated to 650 million years ago {AS, Nov/Dec 2008 p.7). A Canadian reef is more than 100 million years older, but Arkaroola dates from a particularly interesting point in the Earth's evolution.
