To answer the real question you can find out be carbon dating the rocks.
The actual age of a rock can be determined through radiometric dating methods that analyze the decay of radioactive elements within the rock. By measuring the ratio of parent isotopes to daughter isotopes, scientists can calculate the rock's age in years.
the relative age of the rock where it was found.
Geologists generally know the age of a rock by determining the age of the group of rocks, or formation, that it is found in. The age of formations is marked on a geologic calendar known as the geologic time scale. Development of the geologic time scale and dating of formations and rocks relies upon two fundamentally different ways of telling time: relative and absolute.
This fossil is called a index fossil. It is a species that is easily recognizable, widespread, and existed for a short period of time. By determining the age of the rock layer where the index fossil is found, geologists can establish the approximate age of the surrounding rocks.
If the age of a certain rock strata is found by the use of isotopic methods and another nearby strata is found to contain trilobite fossils, assuming there is no unconformity between the two strata we can infer the approximate age of the trilobites within certain parameters.

5-10 I think would be the age group.
the relative age of the rock where it was found.
The most effective way for a scientist to determine the actual age of a rock is through radiometric dating methods, such as carbon-14 dating or uranium-lead dating. By measuring the decay of radioactive isotopes in the rock, scientists can calculate its age with high precision.
the relative age of the rock where it was found.
A Rock Breakage is a rock that breaks when its age is old. They can be found at the Trench where rocks re formed and rocks that are old
