Fig. 8 in Quadrupedal dinosaurs did not evolve fully pronated forearms: New evidence from the ulna
Fig. 8. Comparison of standardized views of semi-pronated forearms in ornithischian dinosaurs that utilized quadrupedalism. A. A tracing of a representative neosauropod sauropodomorph, Apatosaurus excelsus (Marsh, 1879) (YPM 1980), in distal view. B. A hadrosaur, Edmontosaurus annectens (Marsh, 1892) (USNM 3814), reversed, in distal view. C. A stegosaur, Stegosaurus sp. (USNM 11659), reversed, in flexor (C1), distal (C2), and pre-axial (C3) views. D. A ceratopsid, Torosaurus cf. latus Marsh, 1891 (high fidelity YPM 57489 cast of MPM VP6841), reversed, in flexor (D1), distal (D2), and pre-axial (D3) views. E. An ankylosaur, Sauropelta edwardsorum Ostrom, 1970 (AMNH 3032), in flexor (E1), distal (E2), and pre-axial (E3) views. Pre-axial views are in full extension and scaled to equal radial length. Distal views not to scale.
Fig. 6 in Quadrupedal dinosaurs did not evolve fully pronated forearms: New evidence from the ulna
Fig. 6. Comparison of true standardized views of forearm pronation in tetrapods that have evolved a fully pronated manus, in flexor (A1–C1) and distal (A2–C2) views. A. A representative metatherian mammal (marsupial), Virginia opossum Didelphis virginiana Kerr, 1792 (FMNH 166984), oriented in a fully pronated orientation. B. A representative chameleon, Furcifer pardalis (Cuvier, 1829) (FMNH 250433). C. A representative anuran (toad), Bufo blombergi Myers and Funkhouser, 1951 (FMNH 210096). Flexor views are scaled to equal radial length; distal views are not to scale. The reader should note that the distal radial epiphyses of small therians and chameleons are often not located at exactly 180° of pronation relative to their ulnae, as it may not be necessary due to a crouching forelimb posture with moderately abducted elbows (Hutson 2010). Note also that, when present, the full pronation of an anuran manus is accomplished via carpal, not radial torsion (see Schwarz 1935: fig. 10), while the distal radial epiphysis remains in full contact with the plesiomorphically semi-pronated articulation (Ecker and Wiedersheim 1896).

Fig. 3. Isotemnid antebrachia, ulnae A, B, and C; radii D, E, and F. A and D are of Anisotemnus distentus, AMNH 28906; B and E are of Thomashuxleya externa, AMNH 28653; C and F are of Pleurostylodon similis, AMNH 28904. All are shown as being from the right side, but the elements of Pleurostylodon (C and F) and the radius of Anisotemnus (D) are from the left, but digitally reversed to appear as right. Abbreviations are: ap, anconeal process; cp, coronoid process; and ce, capitular eminence. The olecranon process of Pleurostylodon (C) is reconstructed.

Hippopotamus Right Radius and Ulna
This is the right forearm, comprised of the fused radius and ulna of a juvenile hippopotamus (*Hippopotamus amphibius*) skeleton given to the Lapworth Museum by Russell Coope. It is very robust, and large muscle attachment points such as on the olecranon process that extends behind the elbow joint allow the hippo to support its heavy body and move with surprising speed. This specimen was digitised by Jack Mayer Wood using photogrammetry, and is part of a collection of bones from this individual hippo that have been digitised. Source: Objaverse 1.0 / Sketchfab
Juvenille mammoth ulna
# SHCMS:G.10695**** **Mammuthus primigenius.** Age: approx 14000 years. Length 34cm Width 15cm Depth 12cm. This is the right ulna of one of the juvenille Shropshire mammoths. Imaged using a canon 5DS R and Stackshot 3x with turntable to provide 112 images which were then processed using agisoft photoscan at high levels. If you like this model or any others we produce we'd love to hear from you and how you've used them. Source: Objaverse 1.0 / Sketchfab
