how did your group decide the age of each fossil sample?

Answer

Brief Explanations:

Common methods to determine fossil - sample age include radiometric dating (e.g., carbon - 14 dating for younger fossils and uranium - lead dating for older ones), stratigraphic correlation (matching the fossil's layer with known geological time scales), and biostratigraphy (using index fossils to date other fossils in the same layer).

Answer:

Radiometric dating, stratigraphic correlation, or biostratigraphy could be used to decide the age of each fossil sample.
