Based on current anthropological knowledge, it is known that in Sardinia the human Paleo-Sardinian morphology of the Late Neolithic (3500-2800 B.C.), better known as the Ozieri ethnic group, originates from the encounter between two different human races belonging to the Ancient Mediterranean Neolithic: the Danube and the African-Mediterranean ones (fig. 1).

The human types of the Ethnic Ozieri group were dolichomorfic, i.e with elongated skull, broad shoulders, long torso, low to medium height and with more developed upper limbs than lower ones; the same anthropomorphic features are found after all also in the ceramic fragments depicting the stylised facial features of the Ozieri people (fig. 2).

There are no human skeletal remains from the Culture of the Megalithic Circles, with the exception of only a few bones recovered at the site of Li Muri, too few to establish the human race and the number of individuals placed in each grave, and the two skeletons, one of a child and one of a brachycephalic adult, i.e. characterised by a short and wide skull, found in the central cista of the circle tomb of Li Muracci of San Pantaleo-Olbia (fig. 3).
