Transition in Nesting Methods and Behaviors from Non-Avian Dinosaurs to Birds

Kohei TANAKA, Darla K. ZELENITSKY, François THERRIEN, Yoshitsugu KOBAYASHI. Transition in Nesting Methods and Behaviors from Non-Avian Dinosaurs to Birds. Japanese Journal of Ornithology, 2018 Volume 67 Issue 1 Pages 25-40

Abstract:

Archosaurs (e.g., crocodilians, pterosaurs, and dinosaurs including birds) are the most diverse and successful clade of terrestrial vertebrates. An understanding of the nesting methods and behaviors of both extinct (e.g., non-avian dinosaurs) and extant archosaurs (i.e., crocodilians and birds) is crucial for the advancement of our understanding of the evolution and diversification of this clade. The nesting methods and behavior of extinct taxa cannot be directly observed from the fossil record, thus aspects of nesting (i.e., nest type, incubation behavior, and incubation period) may only be inferred and reconstructed based on certain features of fossil eggs, nests, and embryos (e.g., clutch size, egg mass, eggshell porosity, and embryonic osteology). Nests and nesting behaviors were likely to have been diverse among non-avian dinosaurs, and the evolution of these features in archosaurs is discussed..
