How do Paleontologists use the remains of the Trilobites?
Paleontologists use the fossils of different aged trilobites to identify the age of rock formations and fossils in other locations. Similar trilobites found in British Columbia as found in Asia would indicate the rock was nearly the same age from both sites. May also mean that the two locations were once close together, but moved away due to plate tectonics.
What makes a fossil an index fossil?
fossils are preserved animals or plants. but index fossils are fossils have wide distribution,many of them,evolves rapidly, and very easy to recognize. Ammonites are index fossils. The fossils were made only in a certain short time period.
How do you scientists use rocks and fossils to understand age and geological history?
Aside from carbon-14, rocks that can be radiometrically dated are mostly igneous and metamorphic rocks. most sedimentary rocks cannot be dated by this method. this is because many sedimentary rocks are made up of particles eroded from older rocks. dateing these pieces only gives the age of the preexisting rock from which it came.
What are facts about paleontology?
Paleontology is scientists working with fossils. they dig up the fossils and research them. Fossils are making some scientists believe that evolution is true. Some fossils look very similar and it takes a trained eye to tell the difference between them. Sometimes when a paleontologist finds a fossil they can tell the approximiate size, weight and details if the creature would be alive.
How do scientist study plant and animals that lived a million years ago?
Scientists study ancient plants and animals by examining fossilized remains found in rock layers. They use techniques like radiometric dating to determine the age of the fossils. By analyzing the morphology and genetics of these fossils, scientists can reconstruct information about past ecosystems and the evolution of species that lived millions of years ago.
How paleontologists use trilobites fossils as index fossils for various geologic time periods?
Trilobites were rapidly evolving and widespread marine organisms that spanned a number of geologic time periods. Certain types of trilobites only appeared in specific segments of geologic time; therefore, when one of these trilobites is found, you can be certain that the rock layer it is found in is of a certain geologic age.
What do scientists use to mark boundaries in the geologic time scale?
I'm thinking it's index fossils because index fossils tell when or how old the layer it was found in. If that's what your asking.
What do scientists use index fossils for?
Geologists use index fossils to define and identify geologic periods.
To compare the relative ages of fossils scientists sometimes use an easily recognized species called?
To compare the relative ages of fossils, scientists use an early recognized species called an index fossil. An index fossil must have existed for a short period time and must have covered a wide geographical range.

What is a an important tool scientists use to study the relative age of rocks?
Index fossils are used, and are of significant importance in finding the relative age of rock.
How paleontologists use trilobite use fossils as index fossils for various geologic time periods?
yeah

What evidence do scientists use to study the ancient dinosaur?
Scientists use mainly fossils.
What do geologist use index fossils for?
to date a rock layer and other fossils within that layer
What do scientists use the fossil record for?
Recording fossils No.
What are two common tools that scientists use when cleaning fossils?
