[5] 130 million years ago, giant ammonites more than one metre (3.3 ft) wide colonized the ocean that then covered this area of the Préalpes.

[6] Those fossils can be discovered either in the Musée Promenade at Digne-les-Bains, or in situ in the folded and fractured layers of geological sites.

[7] The La Robine ichthyosaur, displayed in the Digne museum, lived during the late Toarcian, 185 millions of years ago.

Its conservation is due to paleogeographic conditions favouring the tilting of blocks, caused by the rifting following the opening of the Piemont-Liguria Ocean.

[9] Also known as sea cows, as they mostly eat algae and aquatic plants, they gave birth to the ancient myth of mermaids.
