Hillyard had already determined that the tumuli were 'reminiscent of the Bronze Age one in Bahrain'.
During excavations at Umm Al Nar, the Ruler's brother, Sheikh Zayed bin Sultan Al Nahyan visited the dig and told the archaeologists that there were many more such artefacts in Al Ain.
Hafit period tombs and remains have also been located across the UAE and Oman in sites such as Bidaa bint Saud, in the UAE and Bat, Al-Khutm and Al-Ayn in Oman.
The Bronze Age Umm Al Nar period spans the period 2600–2000 BCE.The name is derived from the first excavations which took place at Umm Al Nar, an island on the coast of Abu Dhabi, in 1959.Burials at Jebel Buhais (Jebel is Arabic for mountain) date back to the 5th millennium BCE.During the glacial maximum period, 68,000 to 8,000 BCE, Eastern Arabia is thought to have been uninhabitable.and gives its name to the Hellenistic Mleiha period (now more commonly referred to as the 'late pre-Islamic period'), from 300 BCE onwards, characterised by the extensive fortified compound, 'Mleiha Fort', which was discovered in the late 1990s and is thought to have been possibly the seat of an ancient South Arabian kingdom.
The site, located near Madam, in Sharjah, consists of burial sites spanning the Stone, Bronze, Iron and pre-Islamic ages of human settlement in the UAE.This is thought to be consistent with changing patterns of human life as a result of climate change: a spring discovered at Jebel Buhais dried up at this stage, an event contemporaneous with similar discoveries pointing to increased aridity in the interior of Oman.Throughout Southern Arabia, evidence of human inland settlement in the 3rd millennium BCE is scant.One of the largest sites in the country, comprising an area of some five kilometres, the coastal settlement overlooks the Al Beidha Lake.It has been dubbed 'one of the most significant lost cities of Arabia'.as well as the hugely significant ancient city of Ed-Dur.
