Description: Mamenchisaurus is a mamenchisaurid sauropod whose cervical column could reach twelve meters thanks to an unusual count of around nineteen neck vertebrae, the greatest among Sauropoda. Ribbing and accessory articulations braced this elongate lever arm against torsional stresses while feeding along river corridors in Jurassic East Asia.

Features:
  - Neck lengths rival any sauropod clade worldwide
  - Accessory cervical ribs bound successive vertebrae into beams
  - Tail terminations bore slender whiplash segments

Related genera: Brachiosaurus, Diplodocus, Omeisaurus
