Aside from carbon-14, rocks that can be radiometrically dated are mostly igneous and metamorphic rocks. most sedimentary rocks cannot be dated by this method. this is because many sedimentary rocks are made up of particles eroded from older rocks. dateing these pieces only gives the age of the preexisting rock from which it came.
sometimes you can tell there old because of the condition but really you should get it cheek with a museum or a person who knows allot about fossils good luck if you have one i love them im into that stuff too and i hope i answered your question
Superposition is the term that describes the relating the age of a layer of rock by comparing it to the age of a layer above it. New rock is superpositioned over old rock. Geologists work backwards from present with this assumption. Fossils are found in those layers that help the geologists to index the layers when there is a discontinuity. If a geologist knows when an animal or plant became extinct the geologist knows that the rock is earlier than that date if the fossil of that animal is in it.
Usually it is rocks which determine the age of fossils, but if the fossils discovered are already of a known age, the age of the rock can be inferred.
i think they use a special kind of machine,or they trace the lines and march them to others
People want to know about fossils because fossils are history and tell us about history, and a lot of people find history fascinating.
By comparing body structures of living organisms...By studying fossils...And comparing the early development of different organisms.
---- Informations: Paleonthology-is the study about fossils Paleontologists-are persons who study fossils ---- Other Questions??
The fossil record provides evidence about the history of life and past environment on earth. The fossil record also shows that different groups of organism have changed over time.
because they think they are smart in past history
Fossils show the geological history of man and animals.
they can provide history of the past and what geological time frame the fossil was in
Scientists can use fossils to learn about what happened about what Earth was like in the past. A fossil is any evidence A fossil is any evidence that life once existed in a place.

Sedimentary Rocks in Layers
no fossils of organisms with hard parts. the few soft body part fossils found rarely fossilize well.
geologist
they help by showing index rock creations.
scientists compare look for the similarities between fossils and living things.but,only a small part of the organisms that have once lived have been made into fossils.in conclusion the record of fossils is incomplete this tells us that scientists dont have a completed record of changes in life on earth Hope this helps ;D
The vast majority of fossils are found in sedimentary rock.
The geological history of this place is fascinating.She is at university studying geological history.
One unanswered question about geological Texas is the exact origin and age of the Balcones Fault Zone. While it is known to be a significant geological feature, there is ongoing debate among scientists about its formation and the processes that led to its development. Further research and investigation are needed to fully understand the origin and geological history of the Balcones Fault Zone in Texas.
