and stupidly described it as “not unlikeVelociraptor“. I was so mortified when I heard the first draft of the video that I got in touch with the videographer and begged him to snip out the “not un-“. He did a great job, and I bet you can’t hear the join.) ...
thinking it could plausibly belong to a sauropod, after Andy countered every point I raised in my “Saurophaganaxis a theropod after all” push with photos of the same characters in the vertebrae of juvenile sauropods, which led to me agreeing with Andy and the other authors that designatingS...
short version is that OMNH 1123, the holotype specimen of the giant allosauridSaurophaganax maximus, does not definitely belong to a theropod and may actually belong to a sauropod, and the same goes for some of the referred material, namely the atlas and chevrons. Since neither...
I ended the talk with something that’s not in the abstract but should be: all of the ideas in the abstract are hypotheses, not conclusions. They’re crying out to be tested. In the last paragraph of the abstract I highlighted some recent work that I admire, that gives us examples to ...
fig. 3) figured and labeled the epipophysis in one of the cervical vertebrae. The vertebra image in that figure is tiny (nice work, glam-magz!), so here are some sketches ofJobariamid-cervicals (from two different individuals) that I made back in the day when I was doing the resear...
Assuming the scale bar is supposed to be 1 meter (and not 20 meters or 2.0 meters as it is labeled) yields a summed cervical length of 13.4 meters, a summed dorsal length of 3.39 meters, and a cervical/dorsal ratio of 3.96–all admirably close, off by no more than 4cm across 16+...
(and not 20 meters or 2.0 meters as it is labeled) yields a summed cervical length of 13.4 meters, a summed dorsal length of 3.39 meters, and a cervical/dorsal ratio of 3.96–all admirably close, off by no more than 4cm across 16+ meters, if the neck in the ground was articulated...
Carpenter 2018: Figure 3.Drawing made by E.D. Cope of the holotype of Maraapunisaurus fragillimus (Cope, 1878f) with parts labeled. “Pneumatic chambers*” indicate the pneumatic cavities dorsolateral of the neural canal, a feature also seen in several rebbachisaurids. Terminology from Wilso...
And the same thing labeled: And now flipped around so we can see it in medial view: And now that image labeled: And, hey, there are three of our alternative hypotheses on display: the long (many vertebral segments) lumbosacral expansion of the spinal cord, which is reflected in a gradual...
A simplified diagram of the sauropod respiratory system. What I’ve labeled “air tubes” here are the pneumatic diverticula. Air holes in the vertebrae are also known as pneumatic foramina. The shapes of the lungs and air sacs are speculative, but the minimum extent of the pneumatic diverticul...
