To anyone who may be able to help.
I have been trying to find recent references to the age of the Lotena
Formation, Neuquen, Argentina. I have older literature from the 70's in
which some list it as Middle Jurassic and others as Upper Jurassic.
I would be very grateful for any help (guide to references, information or
names and addresses of those who may be able to assist) with this problem.
Please reply off-list to dave.unwin@bristol.ac.uk (fax 44-117-925-3385)
Thanks
Dave Unwin
