The development of the chronological phases, based on recalibrated radiocarbon dating, has split the period up to the Bronze Age in Malta into a number of phases. The first evidence of human habitation in the Neolithic occurred in the Għar Dalam phase, in c. 5000 BC. The Temple period, from c. 4100 BC to roughly 2500 BC, produced the most notable monumental remains. This period is split into five phases; however, the first two of these left mostly pottery shards. The next three phases, starting from the Ġgantija phase, begins in c. 3600 BC, and the last, the Tarxien phase, ends in c. 2500 BC.
