The bone is thin-walled (about 1 mm thick) as seen in all other pterosaurs. In anterior view the dorsal margin is straight, and the ventral margin is concave due to a ventral expansion of the proximal end. Below this expansion there is a prominence, the tuberculum musculi bicipitis (TMB), which is more ventrally displaced than in the ulna of Santanadactylus pricei (AMNH 22552: Wellnhofer, 1985, 1991a; Kellner and Tomida, 2000; BSP 1980 I 122: Wellnhofer, 1985). A small pneumatic foramen is present proximal to the TMB of the abovementioned species, but the preservation of MMCH-Pv 53 does not allow observation of this foramen. The preserved portion of the shaft shows in its anterior face two longitudinal low ridges that suggest the contact area with the radius (Figure 2 B, G). In proximal view there are two concave, anteroproximally facing articular surfaces: a dorsal one, the capitular cotyle (sensu Bennett, 2001), and the ventrally located trochlear cotyle (sensu Bennett, 2001), separated by a sharp prominence. Posterior to this small prominence is a dorsoventrally elongated depression. The posterior margin of the proximal end shows an overhanging rounded and dorsoventrally elongated prominence, the olecranon process: that corresponds to the insertion area for the M. triceps brachii (Figure 2 A, F). Dorsal to this prominence is a wide, posteriorly orientated depression, also present in BSP 1982 I 93 (Wellnhofer, 1985).</p></div>	https://treatment.plazi.org/id/03B4F734FFA7FFE6FF9FFF35FE3FFC41	Public Domain	No known copyright restrictions apply.
