In southern France, a new fossil site has been discovered from the lower Ordovician period. This site contains some of the richest and most diverse fossils from this time period, with 400 well-preserved fossils dating back 470 million years found in Montagne Noire. Scientists from the University of Lausanne and the CNRS analyzed these fossils and published their results in the journal Nature Ecology & Evolution.
The area where the fossils were discovered was close to the south pole during the Ordovician, offering a rare glimpse into polar ecosystems of that time. The fauna present at the site includes arthropods, cnidarians, algae, and sponges. The high biodiversity of these fossils suggests that the area was an ancient refuge for species escaping hot conditions further north.
This discovery sheds light on how organisms responded to extreme climate conditions in the past, providing valuable insight into a possible future under climate change. Amateur paleontologists Eric Monceret and Sylvie Monceret-Goujon made this incredible discovery while prospecting and searching for fossils since their early twenties. They were amazed and excited by their findings and recognized their importance.
