"#Titanomachya gimenezi roamed our planet during the latest #Cretaceous period, around 66 million years ago. The ancient species was a member of a group of derived titanosaurian #sauropods called Lithostrotia and shared some features with the family Saltasauridae."

A bizarre new plioplatecarpine mosasaurid from the #Maastrichtian of #Morocco https://www.sciencedirect.com/science/article/abs/pii/S0195667124000430

"Some #mosasaurs had teeth to pierce prey, others to cut, tear, or crush. Now we have #Khinjaria acuta, with a short face full of huge, dagger-shaped teeth."

New #fossils of Abelisauridae (#Dinosauria: #Theropoda) from the upper #Maastrichtian of #Morocco, North Africa https://www.sciencedirect.com/science/article/abs/pii/S0195667123002057

"the African dinosaur fauna hints that at low latitudes, #dinosaurs were thriving, even diversifying. If so, that means dinosaurs were cut down in their prime; burning out rather than fading away."

"A partial skull originally thought to be from a T. rex might actually represent a previously unknown species... They have named this creature #Tyrannosaurus mcraeensis, after the McRae Formation where it was discovered."

Signs of wear on #mosasaurs' teeth show they were picky eaters who liked #seafood https://phys.org/news/2023-11-mosasaurs-teeth-picky-eaters-seafood.html

"#Prognathodon in particular, with its large cone-shaped teeth, appears to have had a surprising amount of #shellfish in its diet... #Plioplatecarpus, with narrow pointed teeth, showed a striking number of signs of wear. Perhaps it was also fond of #fish with strongly scaled bodies"
