A long time advocate of the use of carbon 14 dating, Waldren took a series of samples from different levels and areas of the Son Mas site and determined that it was first used during the year 2100 BC (this is a calibrated date). In 1992, a second series of radiocarbon dating results determined that this site was continually used from 2100 B.C. to 200 A.D.. This is incredibly significant, because at 2300 years the Son Mas Sanctuary is the longest continuously undisturbed site in Europe. This incredible continuity has provided Waldren and his colleagues with information concerning the entire span of the Bell Beaker society and their development in Mallorca.

Artifactual finds:

Amongst the thousands of pot sherds uncovered at Son Mas, a remarkable six percent have been of the Beaker ware variety, indicating the importance of the site. Beaker ware is a very fine (often only a few millimeters thick), black, artistically ornate type of pottery closely associated with funerary (ritualistic) events. Previously excavated sites which were heralded for the presence of such pottery routinely contained less than one percent Beaker of all pot sherds. The fact that Son Mas contains a frequency of Beaker ware sherds twelve times greater than other Bell Beaker sites attests to its uniqueness.
