Fossils of the Past: A New Discovery Sheds Light on Extreme Ecosystems and Biodiversity in the Lower Ordovician Period

Inexperienced French fossil hunters find ancient fossils with global importance dating back 470 million years

In southern France, a new fossil site has been discovered that dates back to the lower Ordovician period. The site, located in Montagne Noire, contains some of the richest and most diverse fossils from this time period. Scientists from the University of Lausanne and the CNRS analyzed 400 well-preserved fossils dating back 470 million years, which were found at the site. The results were published in the journal Nature Ecology & Evolution.

The discovery of this fossil site offers a rare glimpse into the polar ecosystems of that time. The area where the fossils were discovered was close to the south pole during the Ordovician, providing valuable insight into how organisms responded to extreme climate conditions in the past. The fossils are incredibly well-preserved, with shell-like components and soft tissue fossils such as digestive systems and cuticles.

The fauna present at the site include arthropods, cnidarians, algae, and sponges. The high biodiversity of the fossils suggests that the area was an ancient refuge for species escaping hot conditions further north. This discovery sheds light on how organisms adapted to changing environments in the past and provides valuable insight into a possible future under climate change.

The two amateur paleontologists who discovered the site, Eric Monceret and Sylvie Monceret-Goujon, have been prospecting and searching for fossils since they were twenty years old. They were amazed and excited by their discovery and understood its importance to science.
