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.
Trilobites
Scientists used trilobites as index fossils because they were abundant, had a wide distribution, and had a relatively short existence in the fossil record. This made them useful for correlating rock layers from different locations and determining the relative ages of the rocks.
Paleontologists specialize in the study of ancient extinct animals. They analyze fossils and other remains to learn about prehistoric life forms and their behaviors.
The plural noun is paleontologists.The plural possessive form is paleontologists'.Example: The professor is making a presentation at the paleontologists' conference.
because they changed slowly through time(:
Trilobites are animals that existed millions of years ago. Geologists, anthropologists, and paleontologists study the fossilized remains of this animal.
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.
geology
Paleontologists are especially interested in the study of fossils.
When mammoth remains are found, they are usually turned over to paleontologists. Paleontologists preserve them in controlled environments at natural history museums.
Paleontologists use carbon dating to determine the age of rocks.
The Trilobites was created in 1984.
Trilobites did not have jaws, therefore they could not bite.
Paleontologists study prehistoric forms of life, including dinosaurs, ancient mammals, and early forms of plants. They use fossil evidence to understand the evolution and behaviors of these organisms that lived millions of years ago.

Palaentologists study ancient species by the fossil remains, footprints, by the traces of animals and DNA with comparision with their ancestors
Paleontologists, stratigraphers, and geochronologists worked with geologists to develop the geologic time scale. Paleontologists study fossilized remains of ancient life forms, stratigraphers study rock layers and their relationships, and geochronologists use various dating techniques to determine the age of rocks and events in Earth's history.
