The Arch

The Arch locality is situated on the Bass Coast between Anderson and Kilcunda. The sediments at The Arch locality are made up of a finer grained conglomerate containing a mixture of sand, mud, fossil plant material and the occasional fossil bone. These rocks are the same age as the coarser quartz conglomerates found between San Remo and Punchbowl, but they have come from a different source. A number of fossil bones have been found at this locality over the years, including a small theropod dinosaur tooth, the only theropod tooth found on the Bass Coast outside the Flat Rocks site, near Inverloch. This is also the only site outside Flat Rocks where evidence of fossilised fresh-water molluscs has been found.
