The thigh-bone is enormous, measuring five feet eight inches in length, and is relatively of greater mass than that of _Diplodocus_.

The neck, chest, hips, and tail are correspondingly massive.

The neck is relatively shorter, however, measuring eighteen feet, while in _Diplodocus_ it measures over twenty-one feet.

The total length of this massive specimen is estimated at sixty-three feet, or from six to eight feet less than the largest "long-limbed" dinosaur.

The height of the skeleton at the hips is fifteen feet.
There is less direct evidence that the "thunder saurian" had the power of raising its fore quarters in the air than in the case of the "light-limbed saurian," because no bend or supporting point in the tail has been distinctly observed.
The third type of giant dinosaur is the less completely known "chambered saurian," the _Camarasaurus_ of Cope or _Morosaurus_ of Marsh, an animal more quadrupedal in gait or walking more habitually on all fours, like the great _Cetiosaurus_, or "whale saurian," discovered near Oxford, England.
