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.
