A concretion is a hard, dense mass formed when minerals precipitate in the void spaces between sediment particles, primarily found in sedimentary rocks or soils. This concretion was discovered and excavated from an apartment construction site in Pohang in September 2019, and is currently stored in the Natural Monuments Center. Found in the Duho Formation of the Cenozoic Era in Pohang, it is among the larger sized concretions discovered domestically, with its circular form well preserved, and the discovery site has already been developed making additional discoveries unlikely. Concretions are formed reflecting sedimentary processes within depositional basins and the composition of pore fluids, and can be utilized as paleoenvironmental indicators. As a domestically produced concretion, it possesses high scholarly value through its rarity and aesthetic value in its intact form.
