Yes, a time period can often be recognized by its fossil content, as different geological eras and periods are characterized by distinct assemblages of fossils. These fossil assemblages reflect the types of organisms that existed during that time and can indicate significant evolutionary events, environmental conditions, and mass extinctions. Paleontologists use this information to correlate rock layers and establish a relative timeline of Earth's history. Therefore, the presence of specific fossils can serve as key indicators for identifying and dating geological periods.
Index fossils are original fossil remains, just a specific subcategory of them. Index fossils are used by paleontologists to identify a particular period of time and often a subperiod of time - the specific fossil is chosen as an index fossil because it is very specific to a time period and allows the other fossils and remains around them to be identified to the same time period.
They are called index fossils.

A body of rock defined by fossil content; usually representing a particular interval of time based on that content.
The principle of Fossil succession states that fossil organisms succeed one another in a definite and determinable order. Therefore, any time period can be recognized by its fossil content.
Fossil organisms succeed one another in a definite and determinable order, and therefore any time period can be recognized by its fossil content. -organisms evolve, and organisms become extinct. Proposed by William Smith late 1700's and early 1800's
The Law of Fossil Succession states that fossil organisms originate, coexist, and disappear from the geologic record in a definite sequential order.
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.

yeah
Place it in a time period

they need to use time scales and remember it because they need to know if they find a fossil they need to know around what time it became a fossil
