 Isotope analysis of the remains revealed δ13C values that were typical of those found at many other Southern British Neolithic sites , albeit with significantly higher values of δ15C , which grew over time . Although this data is difficult to interpret , it was identified as probably reflecting a terrestrial diet high in animal protein that over time was increasingly supplemented with freshwater river or estuarine foods . In the case of the older individuals whose remains were interned in the tomb , the tooth enamel was worn away and the dentine had become exposed on the chewing area of the crowns .
