npub1psdfxfpxz2cwmmnsk60y3nqpn2tqh9n24h4hstvfkwvr6eaek9js499sr7 (npub1psd…9sr7) npub1jc0sh3wdfut8hmnmqy8l4smqhnq0y32mn5536mdn9wtsac5geynslnsldg (npub1jc0…sldg) Eggs have a maximum size set by the ratio of surface area to volume as a constraint on gas exchange. The approximately 13cm average diameter of ostrich eggs is into the size range for sauropod eggs, the very largest reconstructed diameters of which max out at about 20cm.
Sauropod eggs tend to be longer and proportionately skinnier than ostrich eggs, so the relative size difference is more than the diameter alone might imply.
