denis, I agree! Mamenchisaurus should win this due to 53-ton weight advantage.
Hopefully you like this match more than Palaeoloxodon vs Diplodocus.

Anyhow, for everyone else, here's a size chart of the femur fragment vs the undescribed but fairly complete skeleton. Palaeoloxodon by Larramendi, Mamenchisaurus by GSP

The larger long necked dinosaur would win easily.
