The cemetery was used only at the beginning of the Late Neolithic I and contained only cremations of children and adults, whose number exceeded 50. The discovery, initially at the cemetery and later at the settlement, of grey (Tsangli phase) and black burnished pottery (Larisa phase) in the same stratigraphical layer, places the Larisa phase at the beginning of the Late Neolithic and not at its end, as was earlier believed. This is of special importance in so as the chronology of Late Neolithic in Thessaly is concerned and has been confirmed at Soufli Magoula and Makrychori 2.

The settlement was inhabited from the end of the Early Neolithic up to the beginning of the Late Neolithic I (Tsangli-Larisa phase). After being abandoned for thousands of years, it was re-inhabited during the Early Bronze Age (3rd millenium BC). Architectural remains of the settlement were discovered at a depth of 4-5 metres from the surface of the ground today, buried under the alluvian deposits of the Peneios river. Geological research in the area has shown that the settlement was organized towards the end of the Early Neolithic Period near the river bank, providing particularly fertile soil for cultivation.
Architectural remains of Platia Magoula Zarkou provide little information about the organization of the settlement in various periods. The discovery of a clay house model beneath the floor of a house of the beginning of the Late Neolithic I has considerable importance for the architecture and society of the period. It depicts a rectangular house with no roof, with a domed oven for cooking and a rectangular elevated construction for relaxation (bench). In the model, 8 figurines were placed symbolizing the members of a Neolithic family. The discovery of the model beneath the floor and close to the hearth, that is at the focus of family life, and the fact that it was found intact, has lead to the conclusion that it was intentionally placed there during the foundation, to ensure prosperity for the house.
