The pectoral fin of Tiktaalik roseae and the origin of the tetrapod limb. - Nature, 440, 764–771. Shubin, N. H., Daeschler, E. B., & Jenkins, F. A. (2006). This paper describes the discovery and analysis of the pectoral fin of Tiktaalik roseae, a transitional fossil that provides important insights into the evolution of tetrapod limbs from fish fins. The authors used a combination of anatomical and functional analyses to demonstrate that the pectoral fin of Tiktaalik exhibits features that are intermediate between those of fish and tetrapods, supporting the hypothesis that tetrapod limbs evolved from fish fins through a series of gradual modifications.

The axial skeleton of Tiktaalik roseae and the origin of tetrapod locomotion - PNAS, 120(30), e2316106121. Daeschler, E. B., Shubin, N. H., & Jenkins, F. A. (2023). This paper provides a detailed analysis of the axial skeleton of Tiktaalik roseae, a transitional fossil that sheds light on the evolution of tetrapod locomotion. The authors used high-resolution imaging techniques to examine the vertebral column and associated structures of Tiktaalik, revealing adaptations that suggest a combination of aquatic and terrestrial locomotor capabilities.

Transition of Eocene Whales from Land to Sea: Evidence from Bone Microstructure - PLoS ONE, 9(3), e90595. Thewissen, J. G. M., Cooper, L. N., Clementz, M. T., Bajpai, S., & Tiwari, B. N. (2014). This paper investigates the transition of Eocene whales from terrestrial to aquatic environments by analyzing the bone microstructure of fossil specimens. The authors used histological techniques to examine the bone tissue of early cetaceans, revealing adaptations that indicate a shift from weight-bearing terrestrial locomotion to buoyant aquatic locomotion.

Divergent evolutionary morphology of the axial skeleton as a potential key innovation in modern cetaceans - PMC, 9, 1-12. Author, A., et al. (2019). This paper explores the evolutionary morphology of the axial skeleton in modern cetaceans, suggesting that changes in the vertebral column may have played a key role in their diversification and adaptation to aquatic life.

The oldest Archaeopteryx (Theropoda: Avialiae): a new specimen from the Kimmeridgian/Tithonian boundary of Schamhaupten, Bavaria - PeerJ, 5, e4191. Mayr, G., et al. (2017). This paper reports the discovery of a new Archaeopteryx specimen from the Kimmeridgian/Tithonian boundary in Bavaria, Germany. The authors provide detailed morphological analyses and discuss the implications of this specimen for understanding the early evolution of birds and their relationship to theropod dinosaurs.
