In 2016, Nutman and his team claimed to have discovered 3.7-billion-year-old stromatolite fossils in the Isua Greenstone Belt of Greenland. If accurate, this finding would predate the previously oldest known fossils in Western Australia by over 200 million years.
How old are the rocks that Allen Nutman studies in Greenland?
Nutman primarily studies rocks in the Isua Greenstone Belt that are more than 3.7 billion years old, dating back to the Eoarchean era. These ancient formations provide vital clues about the conditions on Earth during its early, hostile formation.
Have Allen Nutman's fossil discoveries been controversial?
Yes, his 2016 claim regarding the 3.7-billion-year-old stromatolites in Greenland has been highly debated within the scientific community. Some researchers argue that the structures could be the result of tectonic deformation rather than biological activity.
