Mamenchisaurus

Mamenchisaurus was a species of dinosaur.

Description
Mamenchisaurs were sauropods. Their massive body supported what is likely the longest neck of any natural creature found on Toril. Their neck is a full in length. Their neck contains nineteen vertebrae, which were supported by bony connections. This prevented the mamenchisaurus from bending its neck other than their head.

Combat
When targeted by a predator, mamenchisaurs used their tails as a destructive whip.

Habitat
Mamenchisaurs were found living in swamps.

Biology
Mamenchisaurs were herbivores and solitary creatures. Their long neck allowed them to reach the foliage from any tree.
