19 new mollusc species shed light on the final days of the dinosaurs
A new study published in European Journal of Taxonomy has revealed a remarkable fossil mollusc fauna from the Paris Basin, France.
Even more remarkably, deposits long thought to be Danian have been shown to date to the Maastrichtian, the final stage of the Cretaceous.
The fossils reveal a shallow marine ecosystem near the coast, including species previously unknown from the region and, in some cases, from northwestern Europe.
The findings also establish a new geological unit: the Vertus-Mont Aimé-Esmans Formation.
