The Givetian is one of two faunal stages in the Middle Devonian period. It lasted from 387.7 ± 0.8 million years ago to 382.7 ± 1.6 million years ago. It was preceded by the Eifelian stage and followed by the Frasnian stage. It is named after the town of Givet in France.
Name and definition
The Givetian stage was proposed in 1879 by French geologist Jules Gosselet and was accepted for the higher stage of the Middle Devonian by the Subcommission on Devonian Stratigraphy in 1981.[2]
