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.
As various trilobites belonged to various
periods of time, it is possible by finding out
what the type of trilobite is to also find out
when the fossil was made, that is from what
time period is the rock where it was found.
