Monash University. The DOP has also excavated at 'Ain el-Gazzareen, El Qasr el-Dakhil, Deir el Hagar and Ain Birbiyeh. In 1985, the Petroglyph Unit of the Dakhleh Oasis Project was created by Lech Krzyżaniak, then director of the Archaeological Museum in Poznań, under the auspices of the Polish Centre of Mediterranean Archaeology University of Warsaw. At first, the studies of the petroglyphs focused on the eastern part of the oasis, where rock carvings had been documented by archaeologists already before World War II (Herbert Winlock and Hans Alexander Winkler). The expedition created systematic documentation of both the depictions mentioned earlier in the literature and the newly discovered ones. Aerial photographs proved helpful in this work. Then, under the direction of Michał Kobusiewicz from the Institute of Archaeology and Ethnology of the Polish Academy of Sciences, attention was turned to the area of the Central Oasis where 270 new petroglyph sites were recorded. The current director of The Petroglyph Unit, Paweł Polkowski from the Archaeological Museum in Poznań, extended the area of prospection and created a map showing the distribution of more than 1,300 panels with rock art. The depictions date from the Prehistory to the Islamic period and include images of animals and people (often pregnant women), hieroglyphs, and Beduin markings. In addition, excavations were undertaken at Amheida and Balat under the auspices of the IFAO. In 2018, the fossilized remains of a large dinosaur were discovered here. In 2019, two ancient tombs were discovered at Ber El-Shaghala archaeological site, that date back to Roman Egypt. Dakhleh Trust The Dakhleh Trust was formed in 1999 and is a registered charity in Britain. Its declared aim is to advance understanding of the history of the environment and cultural evolution throughout the Quaternary period in the eastern Sahara, and particularly in the Dakhla Oasis. To this end, the present trustees have committed themselves to supporting the DOP. References Further reading Published works Boozer, A.
