Maison des Faluns, a time travel


Once upon a time there was 15 million years ago, a sea at 26° and an outside temperature of 24°. You could have seen sharks, turtles, corals, sea urchins, manatees … Thanks to falun, a sedimentary rock that has allowed the conservation of many marine fossils, this journey through time is within reach of visitors to the Maison des Faluns.
