True. But no pterosaurs walked, bipedally or quadrupedally, with a
Quetzalcoatlus can, due to the remarkable bony support shelves at the
shoulder and elbow that carry the weight when the elbow is raised well above
the shoulder.. However, that doesn't mean that they did -- walking in that
configuration requires a reversal of the normal direction of the walking
All pterosaurs except "azhdarchids," ctenochasmatids, dorygnathids (that's
one clade) and cycnorhamphids + ornithocheirids (a second clade).
Are you saying that azhdarchids were not soarers?
