Welcome Zavacephale rinpoche ("Zava" means root/origin in Tibetan) from the Early Cretaceous Khuren Dukh Formation of Mongolia!
Gone are the days of Yaverlandia and Stenopelix, as we finally have a definitive Early Cretaceous pachycephalosaurian! The discovery of Z. rinpoche pushes back the origin of pachycephalosauria by around 14 & 16 million years, before the previous record-holders Sinocephale and Acrotholus respectively. The holotype is pretty much the smallest pachycephalosaur we've found, although it could just be because of the specimen's immaturity. Still, it seems pachycephalosaurs had well-developed dome structures on their heads as far back as the Aptian.

On the other hand, we have some more Iberian spinosaur news! In a recent paper on Camarillasaurus, Rauhut and colleagues found the material of Protathlitis (the fella described just over a year ago) had insufficient diagnostic features to be considered a distinct taxon, and therefore a nomen dubium, and found the remains to be chimaeric as well. In addition, Rauhut found even more support for Camarillasaurus as a spinosaur, and even a spinosaurine, as a sister taxon to Spinosaurus itself!
