Areas where sedimentary rocks are being eroded include exposed Mountainous areas, river banks and beds and engineering features like quarries and road cuts. Generally in appearance, a fossil will be either a different color to the surrounding rock, because of the different mineral content, will have a defining shape and texture or a combination of both. Dried up natural lake beads and caves in the form of pitfall traps also has an occurrence of a recent fossil fauna for the locality as is the case with Cuddie Springs and Naracoorte Caves in Australia.
