Detailed explanation-1: -Answer: Fossils are defined as the remains or traces of organisms that died more than 10, 000 years ago, therefore, by definition the minimum time it takes to make a fossil is 10, 000 years.
Detailed explanation-2: -Fossils are the remains and/or traces of prehistoric life. The critical factor is age. Fossils have to be older than 10, 000 years, the generally accepted temporal boundary marking the end of the last Pleistocene glacial event. Fossil remains include bones, teeth, shells, and wood.
Detailed explanation-3: -Buried bone and shell contain tiny air spaces into which water can seep, depositing minerals. Reinforced by these mineral deposits, bone and shell can survive for millions of years. Even if the bone or shell dissolves, the mineral deposits in the shape of the body structure remain.
