Depending on the layers. For a certain amount of years there is a certain amount of layers. So, if a fossil is found on a certain layer then you can figure out how old it is.
Animal fossils have been found in many places in the ocean.
Because, similar fossils could be found on different continents, in rocks of the same age.
Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.
Index fossils help geologists determine the relative age of rock layers by comparing the fossils found in them to known ages of fossils. By identifying specific index fossils, geologists can correlate rock layers from different locations and help determine the chronological order of events in Earth's history.
Fossils are typically found in sedimentary rock layers, which are formed from the accumulation of sediments over time. Fossils are most commonly found in the mid to lower layers of sedimentary rock formations. The specific layer in which a fossil is found depends on the age of the fossil and the geological history of the area.

No. Under the north pole is seafloor. Dinosaurs were land-dwellers
Fossils themselves can very rarely be dated by any means...their age is usually judged by the geological assessment of the area and layer in which they are found
5,000,000,000,000 years old
Radiometric dating of fossils is not possible beyond roughly 70,000 years. However, when fossils are found in association with strata of volcanic and metamorphic rocks which can be dated radiometrically, a very accurate age of the fossils can be determined.
Because, similar fossils could be found on different continents, in rocks of the same age.
Index fossils are used to date rocks by correlating the fossils found in the rock layers with known ages of those fossils. Index fossils are distinctive, widespread, and lived for a relatively short period of time. By identifying these fossils in a rock layer, scientists can infer the age of the rock based on the age range of the known fossil.
Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.
Perhaps by carbon dating and by comparing with the evolution and dominance of various organisms in the geological time scale.
If a lava flow or bed of volcanic ash was dated using isotopic dating methods and fossils were found in a sedimentary rock beneath the volcanic rock, it can be surmised that the fossils were older than the lava or ash. If the same species of fossils were found in another part of the world it would make sense that the rocks there were the same age as previous fossils. By cross checking with many other areas with other volcanic rocks, it can be found that all the rocks around the world containing those fossils were of a similar age.
Fossils have been found with ages from a few tens of thousands of years old to roughly three billion years old.
Fossils are typically found buried deep in the ground, ranging from a few feet to hundreds of feet below the surface. The depth at which fossils are found can vary depending on factors such as the age of the fossil and the geological processes that have occurred in that area.
