Three mounted skeletons of Plateosaurus, a roughly 210 million-year-old ancestor of the more famous “long-necked” sauropod dinosaurs. Photo taken in 2005 at the Museum am Löwentor in Stuttgart, Germany.
These particular mounts are now quite outdated and inaccurate for the current knowledge of these animals. Plateosaurus is now considered to have been fully bipedal — and in fact the forelimbs of the front specimen are in a weird anatomical position just to get it into a quadrupedal posture. (And see that forward forelimb? The elbow is actually dislocated. Ouch.)
And let’s not even get started on the tail-dragging going on there.
Here’s a link to a much more modern example of a Plateosaurus skeleton.
