today the fossil record can be dated

In addition to being tilted horizontally, the layers have been faulted dashed lines on figure. These objects make up the earliest archeological record, which is studied in tandem with the fossil record to piece together hominin life and evolution. Carbon has three isotopes: carbon 12 C , carbon 13 C , and carbon 14 C. The second section discusses how the physical and chemical properties of elements can provide more precise ages. Figure 5: Radioactive isotopes and how they decay through time. Thus, radiocarbon dates must be treated with a certain degree of caution. Figure 2: The principles of stratigraphy help us understand the relative age of rock layers.
