A little more perspective
The museum’s 2017 species announcement identifies the 122-foot model and the fossil material used to reconstruct it. Converted literally, 122 feet equals 37.1856 meters, but the original whole-foot description does not imply millimeter precision. The model is a reconstruction, rather than one complete fossilized animal.
The living-form illustration extends the neck and tail along the horizontal axis. Its skin and muscle envelope are interpretations added around the skeletal reference. Changing the neck pose would change visible height, so this record compares length and does not claim a separately measured standing height.
