The more recent rock layers will contain fossils that are more similar to current species because of evolution. The older the fossils, the more evolutionary changes will exist between them and current species which accounts for the greater differences.

∙ 14y agoMany possibilities, eg. conditions were not right for fossilization, there were no creatures about to be fossilized, or the rock has been altered and all traces of fossilization lost. Some fossil localities will have meter after meter of barren rock, with only very few thin rich layers of fossils. This forms an interesting record of what was going on at the time, and can provide a wealth of clues as to what life was like hundreds of millions of years ago.

What layer is an old fossil found?
fossils are formed in Sedimentary rock
What is called when organisms are trapped in sedimentary rock?
when an organism is trapped in sedimentary rock, it will die and the organism will slowly decay, but it won't decay altogether and you get a fossil. the older the fossil is the lower down it will be in a sedimentary layer. that's called superposition...
What rock encloses a fossil?
sedimentary rock.
What type of rock is a fossil?
A fossil is evidence of an organisms existence, not a type of rock. Most fossils are found in sedimentary rocks.
What fossil fuel is sometimes considered a type of organic sedimentary rock?
Coal is the fossil fuel sometimes considered a organic sedimentary rock.
What layer is an old fossil found?
fossils are formed in Sedimentary rock

The age of the rock layer

Is a sedimentary rock a fossil?
A fossil is any record of an organism preserved in rock, whether it be igneous, sedimentary, or metamorphic. Nearly all fossils are discovered in sedimentary rock.

What fossil fuel is sometimes considered a type of organic sedimentary rock?
Coal is the fossil fuel sometimes considered a organic sedimentary rock.

sedimentary
How do sedimentary rock layers provide clues to a fossil age?
because fossils are in sedimentary rock
