Ancient animal fossil discovered in Norway’s Arctic region

Researchers at the University of Cambridge discovered one of the oldest known 3D fossils of an animal in a sheep field in Finnmark, Norway.
The fossil, dating back 560 million years to the Ediacaran Period, is of a creature called Charnia. This organism resembled a fern and lacked features common to modern animals, such as a mouth or organs, functioning as a stationary, gelatinous life form.
Unlike most fossils from this era, which are flat impressions, this Charnia fossil retained its three-dimensional shape because an ancient underwater avalanche rapidly buried it in seabed sediment. This exceptional preservation allowed scientists to observe previously unseen details, including ridges called “keels” along its branches. The find is noteworthy because Ediacaran fossils are rare, as the organisms from this period generally lacked hard parts like skeletons. Furthermore, rocks from the Ediacaran Period are not widely distributed, making fossil discovery challenging.
The team also found evidence of other organisms at the site, suggesting a potentially undiscovered community of early life existed in the area, and they believe similar fossils may exist in unexplored locations.
