Wing-bone geometry is compatible with short-burst active flight in comparative models, but the evidence does not directly observe behaviour, endurance or a modern crown-bird flight stroke.

Synchrotron wing-bone geometry is compared with living flight modes; flight capacity is inferred biomechanically rather than observed.
Claim ledger
Referred Archaeopteryx skeletons preserve toothed jaws, a long bony tail and feather associations, while wing-bone cross-sections differ from those of specialized soaring birds.
