In the southern French region of Montagne Noire, a new fossil site has been discovered dating back to the lower Ordovician period. The site contains some of the richest and most diverse fossils from this time period, with a total of 400 well-preserved specimens found and analyzed by scientists from the University of Lausanne and the CNRS. The results were published in the journal Nature Ecology & Evolution.
The area where these fossils were discovered was close to the south pole during the Ordovician, offering a rare glimpse into the polar ecosystems of that time. 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 these fossils suggests that the area was an ancient refuge for species escaping hot conditions further north. This discovery provides valuable insight into how organisms responded to extreme climate conditions in the past and may offer clues to how species might respond to climate change in the future.
The two amateur paleontologists who discovered this remarkable site, Eric Monceret and Sylvie Monceret-Goujon, have been prospecting for fossils since they were twenty years old. They were amazed and excited by their discovery and understood its importance immediately.
This new find adds to our understanding of life during this era and could provide valuable information on how species adapt to changing environments over time.
