And is firmly in 'Camp Tyrannosauroidea' for megaraptorans, finding them to be early-diverging within the clade (as per Aranciaga Rolando et al. 2022), not 'mid-grade' as per my 2022 work. It also supports Laurasian (maybe Asian) origins followed by Gondwanan dispersal... 5/n

Lots to think about, making this such an exciting group for hypotheses about theropod evolution in general. The paper is accompanied by this exciting piece of art, credit to Pedro Salas/Sergey Krasovskiy. 6/end #dinosaurs #theropods

Today sees the publication of an exciting new study on megaraptoran evolution by Morrison et al. @cretaceous-cass.bsky.social in R Soc Open Sci that seeks to clarify patterns and biogeography. It's OA and here .... royalsocietypublishing.org/doi/10.1098/... 4/n #dinosaurs #theropods
Rise of the king: Gondwanan origins and evolution of megaraptoran dinosaurs | Royal Society Open Science
Late Cretaceous Earth was dominated by theropods such as tyrannosauroids and megaraptorans; however, it is unclear how these clades diversified and grew to massive proportions. This study aimed to conduct a biogeographical analysis and test climate as a ...
