  Cerin Lagerstätte (France) | |
The Cerin Lagerstätte is a fossil deposit of the Jura Mountains located in Cerin, a hamlet belonging to the commune of Marchamp in the department of Ain. The site is internationally known for its surprising diversity.[1]
The deposits are located in what was a tropical lagoon at the end of the Kimmeridgian age (Late Jurassic). It is dated from the Aulacostephanus pseudomutabilis biozone, whose equivalent in the Mediterranean area is the Aulacostephanus eudoxus biozone, which dates to 153 Ma.[2][3]
Situation
The site belonging to the Bugey historical region was erected at 560 meters above the sea level and is located 20 km off Belley, 75 km off Lyon, 80 km off Grenoble and 90 km off Geneva.[4]
Lithographic limestone
A Jurassic European lagoon.
Cerin was reputed by the end of the 19th century for the quality of its lithographic limestone. The area was, during the Late Jurassic, a tropical lagoon. Lithographic limestone is formed by sedimentation of a very thin carbonated mud deposited at the bottom of a lagoon 153 million of years ago. Those deposits are disposed in strata.
The quarry exploitation, which began in 1835 during the lithography golden age, allowed to periodically uncover prints of prehistoric animals and plants fossilized in stone. Paleontology was at its beginning and those discoveries were still little-known.[3]
Site discovery
In 1838, thanks to the engineer Aimé Drian, a passionate amateur geologist, and Lyonese geologist, and Victor Thiollière, those fossils were discovered and the existence of the paleontological site of Cerin was revealed to the scientific world. The site has an international reputation and rivals with the Solnhofen Limestone, in Bavaria. Until his death, Victor Thiollière never ceased to collect and study a maximum of fossils from the site, and it was, in large part, thanks to his study of the Cerin fossils that he was recognized in the palaeontology world.
His works showed the similarities of the lithographic limestones of Cerin and Solnhofen. He described several new species of fish. He published in 1854 the first part of his "Description des poissons fossiles provenant des gisements coralliens du Jura dans le Bugey" ("Description of the fossil fish from the Jura corallian deposits in the Bugey"), but died shortly before the publication of the second part, the descriptions and lithographic plates already finished.[5]
Research on site
Research on the Late Kimmeridgian site (Late Jurassic, around −153 Ma),[6] occurred from 1975 to 1995, it was a unique operation and involved advanced technology. Directed by geologists from Claude Bernard University in Lyon, it necessitated heavy equipment of civil engineering.
This operation allowed the discovery of algae, ferns, conifers, molluscs, sea urchins, starfish, crustaceans such as the holotypes of Cyclerion bourseaui and Soleryon amicalis,[7] reptiles, fish, as well as tracks of turtles and other reptiles.[8] A thorough study permitted to determine the age and nature of the site (a tropical lagoon 153 million years old) and to understand the reasons of this exceptional fossilization.[1]
A one-of-a-kind Late Jurassic fossilized track of prehistoric marine turtle was discovered in Cerin.
Fossilization process in Cerin
To understand the fossilization process in Cerin, scientists went on an expedition to Aldabra in the Indian Ocean, to observe a fossilization process similar to the one that happened on the Cerin site.
153 million years ago, the climate was tropical. The lagoon had only few contacts with the open sea, and evaporation was intense. Terrestrial animals venturing in the lagoon shores left their tracks in a quickly drying mud.
During storms, a large quantity of saltwater, carrying mud, vegetal remains, and dead or alive animals, entered the lagoon; clearwater, brought by rains and water runoff, brought as well large quantities of particulate matters. When the calm was settling, the fine particles deposited in a regular layer which carpeted the depths and covered remains and tracks.
This layer gave then birth to a strata of lithographic limestone.
When evaporation made the water level drop again, it became under oxygenated and over-concentrated on salt, which led to the death of many living beings, while protecting their bodies from scavengers. The microbial mats, who thrived in this environment, covered the corpses and vegetal remains, helping their conservation as fossils.[1]
