Can anyone tell me the age and stratigraphy of the Miocene shelly sands of Touraine (Savigne / Lathan) Saumur (Doue la Fontaine, Noyant la Plaine) and of Britain (The Quiou) and their correlation? I found the recent articles of Gagnaisson 2013 and Courville 2003. I work on echinoids fauna.
By my simple experience as fossil's amateur I can say that 'Faluns' of Savigné sur Lathan are typically 'Helvetian' in age, i.e. Middle Miocene. As 'Helvetian', also most of Middle Miocene marine sediments of the Torino Hill district, NW Italy, were formerly meant. They are (were) also fossils-rich. Part of such strata now is corresponding to the 'Baldissero Formation'.
Have a nice day,
Domenico
So in the biblio The falun begin in Langhian and end in Tortonian but I don't know the age of the different formations... Thank's
Ask to the paleontology lab of the MNHN in Paris, via its present director Dr Sylvie Crasquin: Sylvie Crasquin
See message sent to you today with attached papers on "faluns" ages
