On almost every ancient camp site are found numbers of 
rejected fragments or cores from which the prehistoric implement 
maker has struck the material used in his work, many of these 
cores or “ turtlebacks,” are nearly circular and are often mistaken 
for implements by collectors. A typical example is shown in 
Fig. 22.
