A 560-Million-Year-Old Animal Survived in 3D, Hinting at an Entire Lost Ancient Ecosystem

A 560-million-year-old animal fossil, called Charnia, was discovered in a sheep field in the Norwegian Arctic. The fossil is the first of its kind in Europe in decades and provides insight into an ancient ecosystem. The fossil is preserved in three dimensions, unlike most Ediacaran fossils, which are found as flat impressions. The team identified subtle ridges on the fossil, called keels, which had never been seen in other Charnia fossils. The discovery suggests the site could contain an entire lost ancient ecosystem. The fossil was formed after being buried in an underwater avalanche, which filled the animal’s body with sediment and preserved it in 3D. The team believes this discovery offers a new perspective on the early evolution of complex life forms. The finding is rare, as most Ediacaran fossils are found in flat impressions, making this a significant breakthrough. The study, published in Paleontology, highlights the importance of this discovery in understanding the early history of life on Earth.
