To date, almost all the modern human crania are from the Samuel George Morton Collection, housed and curated at the University of Pennsylvania Museum of Archaeology and Anthropology. 

The original Morton collection is composed of approximately 1200 human crania (most without mandibles) and which were sent to Morton by others who collected them from both archaeological and recent contexts (1820’s to 1851). After Morton’s death, his student, J. Aitken Meigs, continued with the collection which totals approximately 1800 crania. Although much controversy surrounds the conclusions that were part of Morton’s work especially his use of cranial capacity as a measure of relative superiority of living human races, he took meticulous and copious notes on the geographic and population derivation of the crania, as supplied to him by those who provided him the crania.
