Let's just say that a new skull of an early "human" is found at the bottom of the sea. It is really 1 million years old (let's just say). How can you tell how old it is if you don't know how old the skull is?

Answer
To determine the age of a newly discovered early human skull that is believed to be 1 million years old, scientists would use various dating methods such as radiometric dating (like potassium-argon or uranium-series dating) or relative dating techniques if the skull was found in sedimentary layers.
Key Concept
Dating Techniques in Archaeology and Paleontology
Explanation
When a skull or any other artifact is found, its age is not immediately known. Scientists use dating methods to estimate how old it might be. Radiometric dating measures the decay of radioactive isotopes within the fossils or the surrounding rocks, providing a date range for when the organism lived. Potassium-argon dating is useful for very old fossils because it can date materials that are billions of years old. Uranium-series dating is often used for bones and teeth. If the skull is found within sedimentary layers, relative dating can be used to determine its age based on the known ages of layers above and below the find. Other methods like electron spin resonance (ESR) and luminescence dating can also be employed depending on the circumstances of the discovery. These methods are based on scientific principles and have been refined over time to provide reliable age estimates for archaeological finds.
