Quintic function: Fifth degree polynomial. Rational functions: A ratio of two polynomials. nth root. Square root: Yields a number whose square is the given one. Cube root: Yields a number whose cube is the given one.
These pseudofossils form as naturally occurring fissures in the rock are filled by percolating mineral solutions. They form when water rich in manganese and iron flows along fractures and bedding planes between layers of limestone and other rock types, depositing dendritic crystals as the solution flows through.
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 ...
