Summary: A new somphospondylan titanosauriform fossil, found in the Lower Cretaceous of Morella, Spain, is described. This fossil exhibits unique features and is possibly an early-branching somphospondylan. The discovery supports the somphospondylan hypothesis and reveals the complex phylogenetic mosaic of the sauropod fauna during the Early Cretaceous in the Iberian Peninsula.

Summary: Intensifying macrovertebrate reconnaissance and age-dating techniques in recent decades have provided a more detailed understanding of the impact of the Cretaceous Thermal Maximum on terrestrial ecosystems. A new early-diverging ornithopod, Iani smithi gen. et sp. nov., has been discovered in Utah, USA, adding to the knowledge of Cretaceous fauna. This finding confirms the coexistence of at least five neornithischian clades in the earliest Late Cretaceous terrestrial ecosystems of North America.

Summary: The end-Cretaceous European archipelago was home to a unique fauna of dinosaurs and vertebrates, some of which were dwarves or had features related to their insular habitats. A new study in Spain has identified a new genus and species of theropod dinosaur, Tamarro insperatus, which may have migrated from Asia to reach the Ibero-Armorican island during the Maastrichtian dispersal events. This theropod shows unique characteristics, such as a distinguishing foramen, setting it apart from other troodontids.

Summary: Fieldwork in Bolivia has led to the discovery of numerous aquatic crocodyliforms over the last four decades. New research has identified new Palaeocene dyrosaurid species and reassigned an Maastrichtian crocodylian to Gavialoidea. Additionally, a new phylogenetic analysis suggests a closer relationship between Vectisuchus leptognathus and Elosuchus, leading to a proposed new clade, Dyrosauroidea. Comparisons with geographical and temporal distributions have revealed a new scenario for dyrosaurid dispersal, with a high number of intercontinental interchanges occurring during the Maastrichtian and higher intracontinental diversification in the lower Palaeocene.

Summary: Isolated sacrum fragments, manual ungual phalanges, and a third metatarsal from the Upper Cretaceous (Santonian) Yalovach Formation at the Kansai locality in Tajikistan, are similar to those elements in various dromaeosaurid theropods. They are identified as Kansaignathus sogdianus and further analysis confirms its position as the basalmost Asiatic velociraptorine. It is also the oldest known member of this clade in Asia and worldwide.

Summary: The discovery of a new specimen of Diamantinasaurus matildae in Queensland, Australia provides further insight into this species, including a more complete skull and partial postcranial skeleton. The skull exhibits similarities to the coeval Sarmientosaurus musacchioi from Argentina, supporting their inclusion within the clade Diamantinasauria. Additionally, plesiomorphic features suggest an early-branching position for Diamantinasauria within Titanosauria.

Summary: This study presents the first description of sauropod teeth from the Upper Cretaceous Winton Formation in Queensland, Australia. The teeth resemble those of early branching members of the titanosauriform radiation, supporting a 'basal' titanosaurian position for Diamantinasauria. A comprehensive review of the early titanosauriform global record reveals a transition in tooth morphotypes from diverse at the start of the Berriasian to limited dental variability dominated by titanosaurs by the end-Turonian.

Summary: The study revises and names a well-preserved hadrosauroid dentary as a new genus and species, indicating it as the third hadrosaurid outgroup species in Europe and the youngest non-hadrosaurid hadrosauroid so far. It is suggested to be a close outgroup to Hadrosauridae and potentially originated in Appalachia, supporting the idea of Asian origin for hadrosauroids and dispersal to Appalachia.

Summary: A new alvarezsaurid theropod, Dzharaonyx eski, has been discovered in the Upper Cretaceous Bissekty Formation in Dzharakuduk, Uzbekistan. It possesses unique features, such as opisthocoelous posterior dorsal vertebrae and procoelous posterior caudal vertebrae with a longitudinal canal within the neural arch. The humerus structure is intermediate between two other alvarezsaurid species. Phylogenetic analysis suggests that Dzharaonyx belongs to the Parvicursorinae subfamily.

Summary: Bogolubovia orientalis, the first pterosaur taxon described from Russia, was initially misclassified as an azhdarchid but has now been reclassified as a pteranodontid. A second vertebra, also belonging to Bogolubovia, was discovered at the same locality. This finding confirms the validity of Bogolubovia as a distinct taxon and distinguishes it from other pteranodontids.
