Mamenchisaurus sinocanadorum was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.

Mamenchisaurus sinocanadorum lived during the Jurassic Late period of the Mesozoic Era, approximately 161.5 to 145.0 million years ago.
