What kind of plants did the Mamenchisaurus eat?
The Mamenchisaurus preferred leaves and young twigs of Jurassic trees ( concerning to their long neck):



Araucaria (http://en.wikipedia.org/wiki/Araucaria),

Ginkgo (http://en.wikipedia.org/wiki/Ginkgo).



Sorry, but that`s all I could find. If you accept the different species of Araucaria, you get more than 5.
