How do you see a sedimentary rocks age by looking at the fossils?

Find out what era the Fossil was from and then you can put a relative date on the sedimentary rock, assuming that the fossil was preserved in the sedimentary rock when it had died.
It would not be the actual age because you need to date the radioactive isotopes for that.

What are index fossils and how are they used to determine the absolute age of sedimentary rocks?
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.
How do sedimentary rock layers provide clues to a fossil age?
because fossils are in sedimentary rock
What fossils are useful in determining the relative age of rocks?
Index fossils
What can be used to date fossils in rocks to give an approximate age.?
The study of strata is called stratigraphy. Stratigraphy can be used to determine an approximate age of fossils in rocks.
What two things do sedimentary rocks record?
Sedimentary rocks record; 1. Time (Age) of formation. 2. Environment of formation.

How can the age of a rock be related to fossils?
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.

How do fossils in sedimentary rock help interpret ancient environments?
the type of sedimentary rock determines when other layers in rocks formed and how they shifted. the properties of the species of time periods need certain environmental conditions. these conditions must be what types of environments ancient creatures lived in.
What two things do sedimentary rocks record?
Sedimentary rocks record; 1. Time (Age) of formation. 2. Environment of formation.
What is the principal of paleontological identity?
The Principle of Paleontological Identity is the theory that the layers of sedimentary rocks around the world can be dated by the fossils which they contain. Based on this theory, two layers having the same fossils are regarded as having the same age. This principle is based on the existence of stratigraphic fossils. It is taken in theory to make it possible to correlate sedimentary sequences in distant areas from each other.
How do scientists use sedimentary rock to determine a fossils relative age?
Scientists use sedimentary rock to determine a fossil relative age by studying the rock.
What does relative dating mean?
Relative dating is used to determine the age of a fossil by looking at its position in layers of sedimentary rocks, whose age may have already been determined.
