Concreations rocks.
The forces of wind, water, and time constantly work to shape rocks into a range of shapes, sizes and colours — including ones that look like past life. Scientists call these features pseudofossils. Pseudofossils are formed by inorganic (non-living) processes but look like fossils or other signs of life.

An ironstone (76) is a sedimentary rock that contains more than 15% iron, which may be present as variable proportions of iron-bearing minerals such as goethite, siderite, and berthierine. Sedimentary ironstones may be hard and calcareous and contain quartz grains, ooliths, pebbles, and a wide variety of macrofossils.
tary rock. The power of water and wind, over time, has gradually deteriorated the soft shale rock leaving the much more solid concretions buried within it exposed. This is especially true in the case of Highbanks’ concretions, as shale is easily eroded and breakable. Ohio Shale is visibly distinguished from other rocks by its appearance.Explore Dripping Rock Trail from the nature center at 9466 Columbus Pike in Lewis Center, Ohio. The hike ascends high cliffs.

The cannonballs are formed by minerals precipitating around a core deep within rock strata. The ball-shaped rocks build up over long periods of time. However, it takes another geologic process, erosion, to expose them. A trail near the pullout explores a stream channel which is cutting into the canyon wall.
Clay stone glacial concretions are known by many names around the world. For example, they are called “Imatra Stones” in Finland, “Fairy Stones” in Scotland, Ireland and Quebec, and “Mud-babies” or “Clay Dogs” in Connecticut.
