Archaeologists in Ankara, Turkey, discovered a 66-million-year-old gastropod fossil during excavations at Kulhoyuk in the Oyaca neighborhood of Golbasi district. The fossil dates back to one of the final phases of the Tethys Sea, an ancient body of water that covered parts of Central Anatolia around 250 million years ago. Researchers theorize that the ancient inhabitants of Kulhoyuk may have brought the fossil there from elsewhere, raising questions about its significance and how it was preserved for thousands of years before modern discovery.

A 66-million-year-old gastropod fossil has been discovered at an archaeological site in Ankara, Turkey.
asserted
fossil → discover → Ankara
Excavators uncovered the fossil during work at Kulhoyuk in the Oyaca neighbourhood of Ankara’s Golbasi district.
asserted
Excavators → uncover → district
Researchers believe it dates to one of the final phases of the Tethys Sea, an ancient body of water that once covered parts of Central Anatolia.
asserted
that → believe → Anatolia
The creature existed millions of years before the settlement was established about 5,000 years ago.
asserted
settlement → exist → years
According to the Anadolu Agency of Turkey, the specimen may have been found elsewhere and later brought to Kulhoyuk by the settlement’s ancient inhabitants.
uncertain
specimen → accord → inhabitants
What was the 66-million-year-old fossil found in Ankara
asserted
fossil → find → Ankara
The fossil belongs to a gastropod, a group of mollusks that includes snails and slugs.
asserted
that → belong → snails
It was discovered during archaeological excavations at Kulhoyuk, in Ankara’s Golbasi district.
asserted
It → discover → district
Researchers believe the specimen dates to one of the final phases of the Tethys Sea.
asserted
specimen → believe → Sea
The ancient sea began forming about 250 million years ago and once covered parts of Central Anatolia.
asserted
sea → form → Anatolia
The fossil therefore predates the settlement by millions of years.
asserted
fossil → predate → years
The discovery connects Kulhoyuk’s archaeological history with a much older geological past and gives researchers another clue about the site’s history.
asserted
discovery → connect → history
What makes the fossil’s presence at Kulhoyuk rare
The fossil, however, is about 66 million years old, long before people lived at Kulhoyuk.
asserted
people → make → Kulhoyuk
The gastropod therefore belonged to a much earlier period than the settlement’s inhabitants.
asserted
gastropod → belong → inhabitants
Researchers are considering whether ancient residents may have found the fossil elsewhere before bringing it to Kulhoyuk.
uncertain
residents → consider → Kulhoyuk
This would make the discovery different from a fossil found in the geological setting where it originally formed.
asserted
it → make → setting
It also leaves researchers with questions about how the specimen reached the settlement and why its ancient inhabitants may have chosen to keep it there.
uncertain
inhabitants → leave → it
Mystery behind the fossil’s presence at Kulhoyuk
Researchers are considering whether people living at Kulhoyuk thousands of years ago found the fossil elsewhere and brought it to the settlement.
asserted
people → consider → settlement
However, this remains a possibility rather than a confirmed explanation for how it got there.
asserted
it → remain → ?
Researchers would need to establish where the fossil came from and why ancient inhabitants may have decided to keep it at the site.
uncertain
inhabitants → need → site
Its age adds another layer to the mystery, since the people at Kulhoyuk were handling an object that had formed millions of years before their time.
asserted
that → add → time
The discovery has opened another area of investigation into how the fossil reached the settlement and what significance it may have held for those who lived there.
uncertain
who → open → those
How is the fossil connected to the ancient Tethys Sea
The fossil is believed to date to one of the final phases of the Tethys Sea, an ancient body of water that began forming about 250 million years ago and once covered parts of Central Anatolia.
asserted
that → connect → Anatolia
The gastropod lived along the shores of this sea about 66 million years ago before eventually becoming fossilised.
asserted
gastropod → live → sea
Its discovery at Kulhoyuk therefore connects the archaeological site with a much older landscape shaped by the ancient sea.
asserted
discovery → connect → sea
The finding does not indicate that the settlement existed during that period.
asserted
settlement → indicate → period
Instead, it offers a glimpse into the region’s geological past, long before communities were established at Kulhoyuk.
asserted
communities → offer → Kulhoyuk
How are discoveries helping researchers understand Kulhoyuk
The fossil is the latest notable discovery from Kulhoyuk, where archaeological excavations have been underway since 2021.
asserted
excavations → help → 2021
Archaeologists recently found what they described as the earliest-known seed remains of Ankara’s distinctive ‘Sevgi Cicegi’, or Love Flower, inside a 4,000-year-old Hittite vessel.
asserted
they → find → vessel
The excavation programme is backed by the Turkish presidency and led by Associate Professor Derya Yilmaz Tekin on behalf of Ankara University and the Culture and Tourism Ministry.
asserted
programme → back → University
The work is continuing to uncover evidence from the site and its long history.
