Dinosaur incubation periods directly determined from growth-line counts in embryonic teeth show reptilian-grade development

Birds stand out from other egg-laying amniotes by producing relatively small numbers of large eggs with very short incubation periods (average 11–85 d). This aspect promotes high survivorship by limiting exposure to predation and environmental perturbation, allows for larger more fit young, and faci...
