Relative dating fossils are found in sedimentary rocks that formed when eroded sediments piled up in lowlying places such as river flood plains lake bottoms or ocean floors sedimentary rock typically is layered with the layers derived from different periods of sediment accumulation.
Relative dating is the science of determining the relative order of past events ie the age of an object in comparison to another without necessarily determining their absolute age ie estimated age in geology rock or superficial deposits fossils and lithologies can be used to correlate one stratigraphic column with another.
In addition the oldest known moon rocks are 45 billion years old since the moon and the earth probably formed at the same time this supports the current idea of the earths age you can learn more about fossils dinosaurs radiometric dating and related topics by reading through the links below.
There are two main methods determining a fossils age relative dating and absolute dating relative dating is used to determine a fossils approximate age by comparing it to.
sedimentary and metamorphic rocks and age determination the photo shows rock layering or stratification which is a typical feature associated with sedimentary rocksnatural gas and petroleum are formed and found in sedimentary rocksfossils which occur in sedimentary rocks show the life forms present on earth during geologic time.
relative dating techniques provide geologists abundant evidence of the incredible vastness of geologic time and ancient age of many rocks and formations however in order to place absolute dates on the relative time scale other dating methods must be considered.
