The last of the oldies: a basal rebbachisaurid (#Sauropoda, Diplodocoidea) from the early Late #Cretaceous (#Cenomanian–#Turonian) of #Patagonia, #Argentina https://www.tandfonline.com/doi/full/10.1080/08912963.2023.2297914

"The presence of an early species at Cenomanian-Turonian times, so close to the #extinction of the group, implies that the evolutionary history of #Rebbachisauridae was more complex than previously thought"

A new #titanosaurian (#Dinosauria: #Sauropoda) from the Upper #Cretaceous (Campanian) #Quseir Formation of the #Kharga Oasis, Egypt https://www.tandfonline.com/doi/full/10.1080/02724634.2023.2199810

"Interestingly, all known #titanosaurians from #Campanian-#Maastrichtian deposits in northern #Africa and the then-conjoined #ArabianPeninsula were small to medium-sized for #sauropod #dinosaurs... The same is true for southern #Europe"

A new gigant #titanosaur (Dinosauria, #Sauropoda) from the Upper Cretaceous of Northwestern #Patagonia, #Argentina https://www.sciencedirect.com/science/article/abs/pii/S0195667123000150

#Titanosaurs were the most diverse and abundant terrestrial #herbivores in the Southern Hemisphere landmasses during the Late #Cretaceous. Their high diversity rivals that of the hadrosaurid and ceratopsid #ornithischians of northern hemisphere ecosystems at the same time.

For this #ManospondylusMonday I recommend the article where I discover a newfound appreciation for Araucaria and its long history and co-evolution with dinosaurs. You can read it here: https://www.manospondylus.com/2022/10/sparing-thought-for-some-fossil-plants.html
