A genus-level supertree of the Dinosauria [PDF]

Proceedings of the Royal Society of London. Series B: Biological Sciences, 2002
One of the ultimate aims of systematics is the reconstruction of the tree of life. This is a huge undertaking that is inhibited by the existence of a computational limit to the inclusiveness of phylogenetic analyses. Supertree methods have been developed

Comparative histological analysis of vertebrates reveals Triassic climate variability across southern Pangea. [PDF]

J Anat
Bone tissues of Triassic taxa reveal life history signals consistent with climatic variation across southern Pangea, spanning present‐day Brazil, Argentina, Zimbabwe, and India. Slower growth patterns within the Zimbabwean assemblage suggest a comparatively more arid intracontinental environment than those closer to the coast. Artwork by Andrey Atuchin.

Dinosaur diversification rates were not in decline prior to the K-Pg boundary [PDF]

Royal Society Open Science, 2020
Determining the tempo and mode of non-avian dinosaur extinction is one of the most contentious issues in palaeobiology. Extensive disagreements remain over whether their extinction was catastrophic and geologically instantaneous or the culmination of ...
