Mohammed Naserifard’s research has reportedly been hampered by Western sanctions which denies scientists access to the analytical tools they need.
The drawings marking some of the hillsides outside the western Iranian town of Khomeyn are among 50,000 paintings and engravings found by Naserifard since 2002.
Experts from the Netherlands assessed in 2008 that one cluster of drawings he had found could be more than 40,000 years old.
Many of the etchings are of animals. One of the more striking engravings he has found is that of an ibex deer, thought to be around 4,000 years old.
It’s difficult to accurately date the findings since Iranian scientists are not permitted to use the latest carbon dating technology under sanctions aimed at curbing Tehran’s nuclear program, which prevents the use of uranium analysis in any of the country’s research, the Independent says.
