well the fossils are trace fossils so we are gonna have too go with trace fossils cause it seems like it knows were it is located the print and the hard rock that has been some places for millions and millions of years.

Why are fossils important to evolution?
Fossils give a record as to what organisms lived throughout different time periods. Generally speaking, the lower layers of soil show the oldest fossils, which aids scientists in following the progression of evolution of an organism. Also, radioactive carbon dating is used in dating how old a fossil is by finding the amount of carbon^14, and then calculating how many half lives have passed to reach this amount.
How do forensic scientist help police?
The forensic scientists can help identify the means of death and how long they have been dead. More importantly, the forensic scientists can use the bones of the deceased person to identify their ethnicity, age, height, gender, and specific things about their body. ie, how many times the dead person has given birth if the person is a female.Also, forensic artists can create a sculpture of what the dead person would have looked like in life, if they have access to a skull. This would help the police to identify who was murdered.
Do fossil records help to date fossils?
Fossil records contain radiation, and the older the fossil is, the less radiation it gives off. Scientists study how much radiation is in the fossil record, and they find out how old the earth is.
Do index fossils tell the relative or absolute age of fossils?
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.
Why are fossils so important?
Fossils are important to the humans because they help us learn about animals that are extinct (like dinosours). They can also help us with many clues as to how dinosours became extinct, and what they looked like.
How do fossils in rock layers help scientists identify the age of rocks?
depending on how deep the rock is in the ground tells scientists how old the rock is
What do scientists use index fossils for?
Geologists use index fossils to define and identify geologic periods.
How are sedimentary rock used by scientists to learn about the past?
Sedimentary rock layers are used by scientist help learn by the texture and shapes
How can fossils help geologists match rock layers?
If the fossils that the scientists find are very evolutionarily similar, for example, if they are the same species or genus, then that means that the sedimentary rock layers have some correlation to each other since the two extinct animals that turned into the fossils most likely lived during the same time period. This hints that the two rock layers were both exposed to the atmosphere during the same time period.
What are index fossils and how are they used to determine the absolute age of sedimentary rock?
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 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 fossils help scientists learn about the history of life?
they help by showing index rock creations.
How do fossils help scientist?
Fossils help scientists by leaving a record for scientists to use. Fossils can help show a scientist which type of animal was living in an area during a certain time. This gives scientists a better idea of what that area was like hundreds of millions of years ago all the way through today.
Do fossils help scientists understand climate changes long ago?
Yes, scientists have used fossils to prove that continents were once one big super-continent named Pangaea.
What are index fossil and how are they used to determined the absolute age of sedimentary rock?
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 melting points help scientists?
The melting point can help a scientist identify a substance.
What type of data do scientists study to help them learn about the layers of the Earth?
