Mamenchisaurus jingyanensis was a gigantic herbivore that lived around 150 million years ago and had one of the longest necks of all known dinosaurs.
Mamenchisaurus jingyanensis had:
- a nine-metre-long neck to help it reach leaves high up in trees;
- hollows in its neck bones to reduce the weight of its neck;
- a large and powerful heart to pump blood to the head;
- strong and thick blood vessels to cope with its high blood pressure;
- thick pads of fibrous tissues on its heels to help cushion its great weight;
- a 'second brain' in the spinal cord in the hip area to help control its hind legs and tail.
