Some 46, years ago in what is now the Polish highlands, a Neanderthal man got some food stuck between his teeth. So he did what any self-respecting hominin would do—he reached for a toothpick, according to new research. The teeth were recovered in and kept at the State Archaeological Museum in Warsaw, and only now have scientists given them a thorough inspection. A key finding of the new study are a series of toothpick grooves found on one of the teeth, in what is being interpreted as evidence of oral hygiene among Neanderthals.

Radiocarbon dating has transformed our understanding of the past 50, years. Professor Willard Libby produced the first radiocarbon dates in and was later awarded the Nobel Prize for his efforts. Radiocarbon dating works by comparing the three different isotopes of carbon.

Relative techniques were developed earlier in the history of archaeology as a profession and are considered less trustworthy than absolute ones. There are several different methods. In stratigraphy , archaeologists assume that sites undergo stratification over time, leaving older layers beneath newer ones.
The remains were at first thought to be a Roman Britain era female, however more recent analysis indicates the bones are of a young male. Goat's Hole was occupied throughout prehistory. Artefacts are predominantly Aurignacian , but also include examples from the earlier Mousterian , and later Gravettian and Creswellian periods.
