Pseudofossils are inorganic objects, markings, or impressions that might be mistaken for fossils. Pseudofossils may be misleading, as some types of mineral deposits can mimic lifeforms by forming what appear to be highly detailed or organized structures.

Other types of pseudofossils are kidney ore (round shapes in iron ore) and moss agates, which look like moss or plant leaves. Concretions, spherical or ovoid-shaped nodules found in some sedimentary strata, were once thought to be dinosaur eggs, and are often mistaken for fossils as well.
A concretion is a hard and compact mass formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary rock or soil. [1] Concretions are often ovoid or spherical in shape, although irregular shapes also occur.
In 1894, it was shown that the place where it was found was associated with metamorphism (O'Brien 1970; Adelman 2007). Similar Eozoön structures were subsequently found in metamorphosed limestone blocks erupted from Mount Vesuvius , where high-temperature physical and chemical processes were responsible for their formation ( O'Brien 1970 ).
The term dubiofossil is a portmanteau word used in geology and paleontology for a problematic structure that looks like a fossil but has an uncertain biologic origin. From Latin dubius, and English fossil, the word has been used mainly for remains found in rocks dating from the early history of the Earth (Precambrian rocks), but it is also applicable in other settings such as problematic ...
