Not in at the moment
differences in codiene and hydrocodone There were some variations in the postures and positions between the four different pterosaur species we looked at, but they span quite a range of sizes and anatomical body plans, but these were close enough to one another that it is likely this was a problem for all pterosaurs. It seems this posture, or something close to it, was indeed the one they adopted when sat on the surface. In the positions we recovered, the feet were often low in the water and this matches some of the suggested swimming tracks for pterosaurs, where just the feet left marks on the bottom. However, it does land in stark contrast to the bird-like postures that have been suggested and mean that any pterosaur residing on the surface would have their snouts at or under the surface.
