How this 3D skeleton was made
This 3D model is a reconstruction. Most bone shapes (214 of 259) are borrowed from close relatives and fitted to this species' size and body proportions. The bone shapes are not the actual shapes of this species' fossils. 12 bones were shaped from photos or figures of this species' own fossils. 33 are estimated.

- 3D Skeleton: Borrowed bone shapes from the template "Allosaurus" (T5). As there are no actual body part measurements for this species, its size was determined from the 507 mm femur of one specimen (FPDM-V97122, a juvenile) in the table of Benson et al. (2018), with the humerus matched to the bone length of the same specimen; the proportions of the rest of the body remain as in the template. The individual bone shapes are not from this species, but from the template species. Source of the template skeleton: 3D Skeleton: Created on this site. The bone shapes were traced from outlines of plate photographs and text illustrations in Gilmore 1920 (Bulletin of the United States National Museum 110, out of copyright; named Antrodemus valens at the time), and scaled according to the measurement tables in the same book (complete specimen USNM 4734). Cervical vertebrae were combined into a single component from an illustration where they were drawn connected. Hand and foot digits, ribs, chevrons, etc., have estimated shapes. Pose (2026-09-30): Bone orientations were taken directly as measured in pixels from Fig. 1H of Pacheco et al. 2019 PeerJ (CC BY) (skeletal reconstruction of Gnathovorax in a walking pose) (front leg: femur 50° forward, shin 46° backward, metatarsus 24° forward; hind leg: femur 12° backward, shin 67° backward, metatarsus 16° forward; arm: humerus 40° backward, forearm 66° forward). Since the diagram only depicts one arm, the far arm is slightly swung forward (estimated). The levels of both foot soles were aligned by adjusting the angle of the hind leg's shin (or metatarsus if needed). The sideways turn of the neck and lateral bending of the tail are estimated (the diagram is strictly in lateral view). Rather than a walking diagram of this species itself, bone orientations from a relative sharing the same gait were applied. The neck was turned slightly to the side, and the tail was bent laterally (angles are estimates; the diagram was lateral-only).
- Known bones: Per-species bone table from Cashmore, Butler & Maidment (2021) (Zenodo 5029952, CC0). Because vertebrae are recorded as "at least one found" per section (neck, back, hips, and tail), bones within each section share the same color.
