What is the name for a very old fossil in sedimentary rocks?
A very old fossil in sedimentary rocks is called a "trace fossil" or "index fossil." These fossils provide valuable information about past life forms and help scientists understand Earth's history.
Used to date fossils in rocks to give an approximate age?
Radiometric dating is used to determine the age of fossils in rocks by measuring the decay of radioactive isotopes, such as carbon-14 or uranium-238, in the fossil. By comparing the amounts of the parent and daughter isotopes present in the fossil, scientists can calculate the age of the fossil. This method provides an approximate age of the fossil based on the rate of radioactive decay.
What Process where scientists look at the half life of the chemical contained in rocks around a fossil to determine the age of that fossil?
The process you’re referring to is called radiometric dating, specifically using carbon dating for relatively recent fossils or other isotopes like uranium-lead for older rocks. Scientists measure the half-life of radioactive isotopes within the surrounding rocks, which decay at a predictable rate. By comparing the ratio of parent isotopes to their stable daughter products, they can calculate the age of the rocks and, consequently, the age of the fossil contained within them. This method provides a reliable means of dating fossils and understanding the timeline of life on Earth.
Why are fossil fuels NOT found in metamorphic rocks?
Fossil fuels are not found in metamorphic rocks because the high pressure and temperature conditions during the formation of metamorphic rocks would have altered and destroyed any organic matter present, which is necessary for the formation of fossil fuels such as oil and natural gas. Fossil fuels are primarily found in sedimentary rocks where the organic material can be preserved and transformed into oil and gas over millions of years.
What do scientists use to calculate age when a fossil is too old for carbon dating?
Scientists use techniques such as uranium-lead dating or potassium-argon dating to determine the age of fossils that are too old for carbon dating. These methods rely on the radioactive decay of specific isotopes within the rocks surrounding the fossil to estimate its age.

How do scientists use radioactive decay to date fossil and artifacts?
Because they want 2
How is Oil a fossil fuels?
The definition of a fossil fuel is fuel consisting of the remains of organisms preserved in rocks in the earth's crust with high carbon and hydrogen content. Oil is actually being debated as to whether or not it is a fossil fuel. Most scientists support that it is a fossil fuel and we need to conserve it.
How scientists estimate the age in years of a fossil?
Scientists can use carbon dating to determine the age of a fossil.

Where are gold fossils in fossil fighters?
You can find them in Miraculous Fossil rocks.You can find those in any Fossil Park but it is very hard to find one.They appear as Yellow dots on your sonar,but the yellow dots can also be Fossil rocks,Dark Fossil rocks,and Wonderous Fossil rocks.
Why are fossil found in sedimentary rocks and not in igneous rocks?

How do you tell how old a fossil is by the rock layer?
You can determine the relative age of a fossil by looking at the position of the fossil in the rock layers. The closer a fossil is to the surface, the younger it is relative to fossils found deeper in the layers. To determine the absolute age of a fossil, scientists use radiometric dating techniques on the surrounding rocks to determine the age of the rock layer the fossil is found in.
