What are the fallacies of fossil dating?
One of the biggest fallacies of fossil dating is that they use the rock layer to help determine the age of the fossils, but the fossils are also used to help determine the age of the rock layer.
The rock samples collected from the bottom of the drill hole came from which earth layer?
Lithosphere
Where can you find the oldest fossils in sedimentary rock layers?
It would be found in the lower layers, rather that younger fossils which are found in the upper layers. ♥
Why are there no index fossils in the granite and basalt?
Granite and basalt are both igneous rocks - they are formed from magma extruded into another rock layer or from expulsion from a volcano. The heat of the cooling rock would completely melt any fossils they came into contact with and destroy them, so you don't see fossils in these rocks.
What sedimentary rock often has fossils?
Paleontologists are looking for fossils in sedimentary rock.
What do geologist use index fossils for?
to date a rock layer and other fossils within that layer
Which kind of rock has fossils?
layer rocks
Are index fossils short lived?
studyisland awnser: to date a rock layer and other fossils within that layer
How are fossils related to science?
because it has to do with layers of sedimentary rock; piles of rock get stacked upon fossils which means the bottom layer with the fossils is oldest since it was there 1st
What is a specialist in the study of rocks fossils and earth layer?
people who specialize in rock fossils are called paleontologists
What layer is an old fossil found?
fossils are formed in Sedimentary rock
What type of rock layer are tertiary fossils usually found in?
metamorphic
What are the fallacies of fossil dating?
One of the biggest fallacies of fossil dating is that they use the rock layer to help determine the age of the fossils, but the fossils are also used to help determine the age of the rock layer.
Why are index fossils so important to geologists?
Index fossils are very important to geologists because they identify geological time periods. Index fossils are found within a specific layer of rock- So when one finds the age of the rock layer, that is also the age of the index fossil.
A scientist identifies a variety of fossils in a layer of sedimentary rock By applying the principle of fossil succession the scientist can identify?
The age of the rock layer
What can you infer about other fossils in the same rock layer as trilobites?
It can be assumed that the organisms that created the fossils were a part of the same depositional environment and process, and roughly from the same time span of the rock that comprises the layer.
What fossils can be formed from plant leaves a thin layer of carbon on rock?
A fossil fuel
