Fossils found in the lowest geological strata are generally the oldest. This is because the law of superposition dictates that older rock layers are found at the bottom, with each successive layer above being younger. Therefore, fossils found in lower strata are older than those in higher strata.

the fissils in the upper strata are younger than thos in the lower strata.
Yes, fossils found in the lowest geological strata are generally more primitive compared to those found in higher strata. This is because the lower strata represent earlier geological time periods when simpler life forms existed, while more complex life forms evolved and appeared in higher strata over time.
They're called strata. Strata less than 1cm thick are Laminae.
Strata can be found in sedimentary rocks, which form in layers over time as sediments accumulate and compact. Igneous rocks, which form from molten magma cooling and solidifying, do not typically have distinct layers or strata.
By knowing which strata it was found and the rate of the strata's being laid down. finding fossils in that same strata.
If the age of a certain rock strata is found by the use of isotopic methods and another nearby strata is found to contain trilobite fossils, assuming there is no unconformity between the two strata we can infer the approximate age of the trilobites within certain parameters.
Strata are the layers of the earth. The deeper the layer, the older the objects that are found in the layer will be. Archaeologists use this as a common way to date objects.
