The techniques used to calculate the date of a fossil aren’t perfect and are subject to error.

Exposure from the sun on a piece of bone, for example, accumulates nitrogen in the bone fragment.

This nitrogen turns into carbon-14, which acts as a measuring guide for how old an object is.

The level of carbon decay may have varied across different time periods in the past.

Some species may have had less exposure to sun, or climate change may have influenced the amount of carbon in the atmosphere.
