Apt and the Aptian age
Here is a modern landscape - a man-made lake, a factory, a shopping area - extending across geologically historic lands: those which, in the 19th century, enabled Alcide d'Orbigny, one of the first French geologists, to create the Aptian age.
The Aptian age is a geological timescale occurring on a worldwide scale. Press on "Play" to find out more about Alcide d'Orbigny and his discovery.
