The fossil was exhibited at Zoology Museum in Diyarbakır province, which features around 2,000 endemic animals including a hermit ibis, giant reptile and leopard carp.
The nummulite was found by Büşra Bektaş, a molecular biology student at Dicle University in Diyarbakır, during a family picnic in southeastern Siirt province.
The term "nummulite" means "coin" in Latin.
"Many areas including Anatolia [peninsula of land that today constitutes the Asian portion of Turkey] was underwater previously. When Anatolia rose, fossils appeared," Ali Satar, a zoology professor at Dicle University, told Anadolu Agency.
"These areas, where fossils exist, could not be able to be searched due to terror incidents. When we do a search in the area, we will find many fossils," Satar added.
Bektaş, who found the nummulite, expressed her excitement about finding such a fossil.
"There are many such things there. I want there to be researched. Because those areas were underwater before. Existence of such organisms in those areas makes me excited," she said.
