Invitation to a Journey through Space and Time
I had my first chance to explore the re-opened Catacombs under Paris in December. We were lucky enough to visit when such a unique place, full of natural history as well as the macabre structures of human bones was eerily quiet as the minus temperatures above chilled the city air.
"Between street level and the bottom of the Catacombs, the visitor is taken back nearly 45 million years in time. You go through a succession of increasingly ancient layers of rock until you reach a bed of limestone whih corresponds to a geological period called the "Lutetian" (between 48 and 40 million years ago)."
"This period was first identified in Paris called "Lutetian" after the ancient name for Paris, Lutetia. The official reference profile (GSSP) for Lutetian is located in the catacombs, at the water-well that bears the name Bain de pieds des carriers ("The Quarrymen's Foot-bath")."
"The Lutetian doesn't actually account for very much time in the history of the Earth, which is 4,500 million years old. The dinosaurs disappeared 65 million years ago, while modern Man has only been developing for 200 000 years,"
