Quick post this evening because I have been out at the museum and a monthly social gathering most of the day/evening. This a quick video showing a CT scan series through the proximal half of the humerus of the mid-sized pterosaur Bennettazhia oregonensis
. This animal was one of the critical specimens in the original quadrupedal launch work, and is also interesting in that it was found in Oregon (pterosaurs from the Northwest U.S. are quite rare). If you look closely, you can make out some of the internal bracing.
