Figure 1. Eudimorphodon ranzii nests at the base of all non-dimorphodontid pterosaurs. Here bones are colorized using DGS and reconstructed below in several views. I can’t identify all the bones here, just the easy ones. Red spot in orbit is the rotated pterygoid with teeth. Other pterosaurs don’t have such teeth, but then other pterosaurs don’t have such marginal teeth either. Line art from F. Dalla Vecchia.
This is Eudimorphodon (Late Triassic), the basalmost of all the non-dimorphodontid pterosaurs. The in situ skull is crushed (Fig. 1), so if you want to see what it looks like in three views you take the parts and put the model back together.
Figure 2. Lateral, dorsal and cross-sectional views of Eudimorphodon ranzii. Note the overlap of the posterior ribs over the hind limbs and the very wide torso. The cross section shows the 2nd dorsal ribs and the 23rd. Note the small ischium which could only produce small eggs. A little taller and wider than we thought before. The forelimbs are pretty short relative to the torso.

We looked at
the post-cranium of Eudimorphodon earlier here. The torso is weirdly flattened, like that of Sharovipteryx, making the entire body a wing shape.
