A little more perspective
The museum’s dinosaur directory lists eight meters and identifies magniventris as the type species. It also notes that a complete Ankylosaurus skeleton has not been found. The figure is therefore a reconstructed size reference, not a direct measurement of a complete living animal.
The tail club remains part of total length, while the back armor rises away from the length axis. The museum explains that the exact arrangement of the back armor is uncertain. The illustration’s osteoderm pattern, colors and soft tissues should be read as restoration choices.

For a presentation or a research note, include the subject, the measurement definition, and the assumed measurement. A picture alone cannot explain those choices. The comparison guide explains how to export an image and its source notes together.
