One method of relative dating
As the word relative tells that defining the object with respect to the other object, it will be pertinent to mention here that actual numerical dates of the rocks or sites are not known in this type of dating.
Other than rocks, fossils are the other most important elements in relative dating as many organisms have there remain in the sedimentary rocks.
Geological specimens that are unearthed need to be assigned an appropriate age.
To find their age, two major geological dating methods are used.
These techniques are more complex and advanced regarding technology as compared to the techniques in practice in relative dating.
The absolute dating is also sometimes referred to as the relative numerical dating as it comes with the exact age of the object.
Biostratigraphy: An extended version of stratigraphy where the faunal deposits are used to establish dating.
In other words, we can say that in relative dating the archaeologist determines that which of the two fossil or the artifacts are older.
Contrary to this, absolute dating is the technique, using which the exact age of the artifacts, fossils, or sites are ascertained.
Faunal deposits include remains and fossils of dead animals.
Cross dating: This method compares the age of remains or fossils found in a layer with the ones found in other layers.
Most commonly, the ancient factors of the rocks or objects are examined using the method called stratigraphy.
