After The Ice Age..
One other campsite of related age has been discovered on Burry Holms (Gower). At this time Burry Holms is a tidal island however, during the Mesolithic, sea levels were much lower and the island would have been an inland hill overlooking the plain of the River Severn. The rise in sea levels that has occurred since, is a consequence of the melting of ice sheets far to the north.
Excavation at the location has produced a spread of finds, together with small stone barbs (microliths) used for hunting, and tiny saws. These may have been used for reducing plant stems to make thatch, twine, or fibre for basketry.
Communication between groups may have been fairly simple because it is probably going that individuals spent a part of their yr travelling in pursuit of herds of animals and other important meals sources. Through the heat summer months it is probably going that they have been to be found in inland areas, while in winter they returned to the decrease mendacity coast or river valleys.
Possibly an important Mesolithic site so far found in Wales is at Goldcliff (Newport). This site lies in the fashionable intertidal zone but, round 7,500 years in the past, it sat on a small wooded island surrounded by saltmarsh.
In addition to stone instruments, pollen, animal and fish bones have been also preserved at the positioning. Fish is believed to have been vital within the diet of Mesolithic people. Their stone microliths (barbs) red stone island cap would have been attached into wooden spears, best for fishing.
