摘 要:Our image of early dinosaur eggs must change.Early dinosaur eggs are portrayed as soft-shelled,like those of modern lizards or snakes[1],and yet all the evidence is that early dinosaurs at least laid leathery-shelled eggs,more like some turtle eggs such as Chelydra serpentina and Pseudemys nelsoni.This matters because the protective egg is key to the success of dinosaurs,as well as modern reptiles and birds.Han et al.[2]present a detailed account of the nest of an Early Jurassic sauropodomorph and the eggs are leathery,not soft-shelled or hard-shelled.
