Artistic reconstruction of the Cabrières Biota. Credit: Christian McCallNearly 400 remarkably well-preserved fossils going back 470 million years have been discovered in the south of France by 2 amateur paleontologists. This brand-new fossil website of around the world importance has been evaluated by scientists from the University of Lausanne, in collaboration with the CNRS and global groups. This discovery supplies extraordinary details on the polar communities of the Ordovician period.Paleontology lovers have actually discovered among the worlds wealthiest and most varied fossil websites from the Lower Ordovician duration (around 470 million years ago). Found in Montagne Noire, in the Hérault department of France, this deposit of over 400 fossils is identified by an incredibly unspoiled animals. In addition to shelly parts, it consists of very rare soft elements such as digestive systems and cuticles, in a remarkable state of conservation. This biota was when situated extremely close to the South Pole, exposing the composition of Ordovician southernmost ecosystems.Groundbreaking Research at UNILAt the Faculty of Geosciences and Environment at the University of Lausanne (UNIL), researchers have worked together with the CNRS and global teams to bring out the first analyses of this deposit, understood as the Cabrières Biota. The outcomes are released in Nature Ecology & & Evolution.Sylvie Monceret is among individuals who found biota.

The websites high biodiversity suggests that this location functioned as a refuge for types that had escaped the high temperature levels prevailing more north at the time.” At this time of intense global warming, animals were undoubtedly residing in high latitude refugia, leaving extreme equatorial temperatures,” explains Farid Saleh, scientist at the University of Lausanne, and very first author of the research study. “The far-off past gives us a look of our possible near future,” adds Jonathan Antcliffe, scientist at the University of Lausanne and co-author of the study.Eric Monceret is among individuals who found the biota.

This very first publication marks the start of a long research study program involving massive excavations and thorough fossil analyses. Using innovative approaches and methods, the objective is to reveal the external and internal anatomy of the organisms, along with to deduce their phylogenetic relationships and modes of life.Reference: “The Cabrières Biota (France) supplies insights into Ordovician polar communities” 9 February 2024, Nature Ecology & & Evolution.DOI: 10.1038/ s41559-024-02331-w.
