Mamenchisaurus

Notable for its incredibly long neck, which can grow up to 11m – roughly half of the its overall length – Mamenchisaurus is one of the largest sauropods to have existed. This herbivorous dinosaur feeds on plants and leaves, swallowing vegetation whole without the need for chewing. Mamenchisaurus’ name derives from the place of its discovery, the Mamen Brook in Sichuan, China.
