After a three-year excavation of the Piltdown gravel pit in Sussex, England, Dawson had unearthed human-like skull fragments and a jaw with two teeth, along with a variety of animal fossils and primitive stone tools. Dawson and Woodward announced that one of the skulls and the jaw belonged to a primitive hominid, or human ancestor, who lived some , to 1 million years ago. The scientific community celebrated Dawson’s discovery as the long-awaited “missing link” between ape and man and the confirmation of Charles Darwin’s theory of evolution.

As the decades passed and new information came to light, however, it became clear that the Piltdown Man was not what he seemed. Significant evidence of early humans in the British Isles had not yet been found, and the success of the Sussex dig was a major headline-grabber. None of them showed the large brain and ape-like jaw of Piltdown Man; instead, they suggested that jaws and teeth became human-like before a large brain evolved.

In prehistoric archaeology, geographical methods are of importance in the determination of the relative age of archaeological finds. Image Source The Principle of Stratification I have already pointed out the importance of stratification when deposits are found in the open veld, in caves and rock shelters, in rubbish heaps associated with ruins, etcetera. At these sites the lowest layers are usually the oldest, while the topmost layers are of more recent origin we have already discussed the terraces of rivers, where the sequence is reversed.

Stratigraphy refers to the description or study of the observable layers of sediments. Strati-graphic dating is a relative dating technique based on the knowledge that layers of sediments are normally laid on top of each other through time, in turn based on the geological law of superposition. Image Source Usually the relative age of objects can be directly deduced from the strati-graphic conditions existing in a given number of strata. Stratification is the basis of every chronological investigation.
