Cranial anatomy and stratigraphy of a new specimen of the tyrannosaurine dinosaur Daspletosaurus from the Judith River Formation of Central Montana, USA [PDF]
Acta Palaeontologica PolonicaThe tyrannosaurine Daspletosaurus contains three recognized species from the Campanian of Montana and Alberta: Daspletosaurus torosus, Daspletosaurus wilsoni, and Daspletosaurus horneri. The recently named D. wilsoni has been proposed to represent a

Strong support for a heterogeneous speciation decline model in Dinosauria: a response to claims made by Bonsor et al. (2020). [PDF]
R Soc Open Sci, 2021 Through phylogenetic modelling, we previously presented strong support for diversification decline in the three major subclades of dinosaurs (Sakamoto et al. 2016 Proc. Natl Acad. Sci. USA 113, 5036–5040. (doi:10.1073/pnas.1521478113)).

Variability in biological diversity of dinosaurs and types of their diet [PDF]
E3S Web of Conferences, 2023 Biodiversity analysis underlies macroevolutionary studies and allows to identify mass extinctions. Numerous studies of mass extinctions show that geological factors play a central role in determining the diversity dynamics. The late Cretaceous extinction
