The Heavy Neolithic and Neolithic material was mostly in a creamy chert and consisted of adzes, chisels, oval axes with retouch all over, racloirs, cores and discs. Lorraine Copeland made a collection of similar materials in 1966 and noted the problems assigning material to specific periods. It seemed apparent that the Neolithic flint knappers had re-used older Acheulean tools and that the site had been a factory throughout numerous periods in a long and ancient history.[1]
