Paleonet: Cenomanian stratotype collections

[MOREL Nicolas]

Dear colleagues, 

I'm in charge of a book about the Cenomanian stratotype (Cenomanian of the departement of Sarthe, area of the city of Le Mans, western France).
I'm looking for museums or university which care paleontological collections from the Cenomanian of Sarthe (e.g. localities of Le Mans, Coulaines, Yvré-l'Evêque, Bousse, Coudrecieux, Ecommoy, Lamnay, La Trugalle, Ballon). 
Best regards
