How this 3D skeleton was made
This 3D model is a reconstruction. Most bone shapes (386 of 408) are estimated from close relatives and published reconstructions. The bone shapes are not the actual shapes of this species' fossils. 22 are borrowed from close relatives.

- 3D Skeleton: A reconstruction created for this site from freely usable sources (research papers, out-of-copyright books, and Wikimedia photos) (2026-10-05). Of the 408 bones (excluding teeth), 0 bones were shaped from photos, drawings, or measurements of actual fossils of this species; 22 bones borrowed shapes from close relatives and were scaled to size; and 386 bones were estimated. Sources used: Zhao 2026 PeerJ doi:10.7717/peerj.21146 (https://creativecommons.org/licenses/by/4.0/) / Wikimedia Commons (authors listed in figures.json) (CC BY 2.0 / CC BY 4.0 / CC BY-SA 2.0 / CC BY-SA 3.0 / CC BY-SA 4.0 / CC0 / Public domain). For papers that are not freely usable, only factual data such as stated measurements were referenced. Important note: About one-third of the well-known Harvard University mounted skeleton (MCZ 1285) is plaster restoration, and a 2021 study reportedly reclassified it under a different name (Eiectus longmani) (based on secondary sources). The only fossil definitively confirmed as Kronosaurus is a fragment of the lower jaw. This 3D model is a reconstruction shaped from its close relative Liopleurodon, matched to that skeleton’s estimated total length (about 10.4 m, Zhao 2026).
- Discovered bones: 2 bones are documented in the literature as fossil finds or visible in photographs (the rest are undiscovered, or unknown from the literature)
