Gastropods fossils.

Most commonly gastropod (snail) fossils. Some coiled shapes may also be goniatites, a type of small ammonite. Found in sandstone along the Walsh River in north Queensland; Some graptolites are coiled. These are easily differentiated from gastropods and goniates, in that they have saw-toothed edges.
