The paper reports 215 exposed eggs in a 3.28-square-metre block, up to about 300 in that block, and 16 embryo-bearing eggs; behavioural and hatchling-flight claims are treated as interpretations.
The Hamipterus site preserves hundreds of three-dimensional eggs, including 215 exposed in one block and 16 containing embryonic remains across at least four levels; storm transport, colonial nesting, hatchling flight ability and parental care remain interpretations of context and development.
claim:event:hamipterus-egg-assemblageHamipterus is represented by eggs and embryos from at least four stratigraphic levels at the Shengjinkou locality; those repeated local horizons do not establish a global genus range or nesting distribution.
