If the isochron slope is 0.0077 what is the age in millions of years when first evidence of abundant fossils?
Q: If the isochron slope is 0.0077 what is the age in millions of years when first evidence of abundant fossils?
How did fossils provide evidence for contental drift?
Because, similar fossils could be found on different continents, in rocks of the same age.
What can rock fossils and original remains show about earths rock?
it can show a rocks age and what it has gone through
What fossils are useful in determining the relative age of rocks?
Index fossils
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.

What sentence best describes the information provided by radiometric dating?
Age is based on fossils that are found in the rock.
What was Elizabeth Proctors age in The Crucible?
By calculating the evidence provided. I have made the conclusion that she is indeed a certain age.
What fossils are useful in determining the relative age of rocks?
Index fossils
The age of the earths crust can best be determined from the studies of A the salts of the oceans B the type of fossils left behind C erosion from a river D radioactive decay E surface weatherin?
Radioactive decay

Fossils such as trilobites that can be used to estabish the age of rocks are called?
I think they are called Index Fossils...
Why do scientist use radioisotopes to find the age of fossils?
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.
Can you tell the age of the earth from fossils?
no but you can tell the age of the fossil from the age of the rock around it, you cant tell the age of the earth from fossils is because animals with bones were didnt exist until later in the earth's "life"
