Summary: Ondogurvel alifanovi, a new species of alvarezsaurid, is described in this study. It differs from other alvarezsaurids in the complete fusion of metatarsals II and IV in the contact area. Phylogenetic analysis places Ondogurvel in a clade with Late Cretaceous Asian parvicursorines Xixianykus and Albinykus. Two morphological types of the parvicursorine carpometacarpus are recognized.

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 cranial remains of non-avian theropod dinosaurs from the Cretaceous period in Australia are poorly understood. This study presents new evidence of non-mandibular cranial material, possibly belonging to the Megaraptoridae family, and contributes to the limited knowledge of Australian Cretaceous theropod cranial remains.

Summary: The Feliz Deserto Formation in NE Brazil preserves some of the earliest fossil records of the Gondwana supercontinent break-up during the Early Cretaceous. Recent discoveries include a new spinosaurid theropod tooth and various other fossils, expanding the fossil record of spinosaurine theropods and neosuchian crocodyliforms in Gondwana. The taphonomic features of the new fossils suggest a low fluvial transport prior to burial, and the depositional paleo-environment of the Canafistula 01 locality is compatible with a deltaic system unit.

Summary: The Lower Cretaceous in England has yielded a diverse assemblage of dinosaurs, including ornithischians, sauropods, and theropods. A newly discovered dromaeosaurid dinosaur, Vectiraptor greeni, from the Isle of Wight shows similarities to Early Cretaceous eudromaeosaurs from North America, suggesting faunal interchange between Europe and North America. The Early Cretaceous dinosaur assemblage in England and Europe resulted from dispersal from North America, Asia, and West Gondwana.

Summary: The Snake Creek Tracksite in the Upper Cretaceous Winton Formation of Queensland, Australia, presents an important vertebrate ichnoassemblage, including the first sauropod tracks reported from eastern Australia. This site also preserves a small number of theropod and ornithopod tracks, as well as the first fossilised crocodyliform and possible turtle tracks reported from Australia.

Summary: This study presents two trackways of fast-running theropods from the Lower Cretaceous Enciso Group of Igea (La Rioja) and compares them with other fast-running theropod trackways published to date, suggesting a basal tetanuran, possibly a carcharodontosaurid or spinosaurid, as the probable trackmaker. Speed analysis reveals that these trackways demonstrate some of the highest speeds ever calculated for theropod tracks, shedding light on the biodynamics of dinosaurs and their movement patterns.

Summary: The Upper Cretaceous Bissekty Formation in Uzbekistan has yielded various non-avian theropod dinosaur remains, including a large dromaeosaurid and a neovenatorid carcharodontosaurian named Ulughbegsaurus uzbekistanensis. However, the classification of Ulughbegsaurus uzbekistanensis remains uncertain due to the lack of definitive diagnostic features. Furthermore, a giant dromaeosaurid and a medium-sized tyrannosauroid called Timurlengia euotica coexisted in the same formation.

Summary: This passage describes the discovery of a unique tooth from the Ifezouane Formation in eastern Morocco, which exhibits a series of severe paleopathologies, including enhanced inner curvature to the crown and the formation of three deep grooves. This is the first report of external dental pathologies in a spinosaurine spinosaurid tooth.

Summary: Dineobellator notohesperus, a recently described dromaeosaurid from the late Cretaceous of the southwestern United States, exhibits unique physical attributes and pathologic features. Its presence reveals physical variation among dromaeosaurids and suggests the coexistence of multiple dromaeosaurids in its environment.

Summary: This study reports two new Early Cretaceous spinosaurid specimens from the Isle of Wight, which form a new clade within Baryonychinae and indicate a European origin for Spinosauridae with at least two dispersal events into Africa. These new finds contribute to updated palaeobiogeographic reconstructions for the clade and suggest potential sympatry between baryonychines and spinosaurids as a whole.

Summary: This study investigates the functions and formation process of the hand claws of early-branching maniraptoran dinosaurs using finite element analysis and functional-space analysis. The results show distinct functional divergence among the hand claws, with early-branching ones being used for digging and late-branching ones for display. The study also confirms that most therizinosaurians were herbivores.

Summary: This study describes a partial skeleton of a megaraptorid from the Maastrichtian beds in Argentina, which is the most informative megaraptoran known from this time period and is identified as a new taxon. Phylogenetic analysis shows that South American megaraptorans form a monophyletic clade, while Australian and Asian members are stem groups. South American megaraptorans differ from more basal forms in several anatomical features and are larger and more robustly built.

Summary: The Kem Kem Compound Assemblage along the Algerian-Moroccan border is a fossil-rich area known for its large-bodied theropod dinosaurs. Two species of carcharodontosaurid allosauroids have been discovered there. However, the validity of the second species has been challenged, and all carcharodontosaurid material from the Kem Kem Compound Assemblage has been referred to the first species.

Summary: Spinosaurid dinosaurs had a wide distribution in Gondwanan and Laurasian landmasses during the Lower Cretaceous and the Cenomanian. European spinosaurids are more diverse than previously known, with five or possibly six recognized genera. A revision study of CPI 477, a maxilla fragment from the Lower Cretaceous of La Rioja, Spain, has shown that it does not belong to the Baryonyx genus but is likely closer to an indeterminate baryonychine. The study also reveals insights into the tooth replacement process and anatomical differences among spinosaurids.

Summary: By analyzing oxygen and carbon isotope compositions in sedimentary deposits of Japan during the Cretaceous, the study revealed changing environmental conditions from cool temperate to warm temperate climates. The findings indicate significant variations in temperatures over time and climatic changes during different periods.

Summary: This study examines the dietary practices of the Gallic population through stable isotope analysis of bone samples from a Gallic site in France. The results suggest that the Gallic individuals followed a continental omnivorous diet based on plants and cattle meat, with a possible marine contribution. This study deepens our understanding of the cultural practices of Gallic tribes during the Second Iron Age.

Summary: Dinosaur eggshell fragments found in northeastern Russia are one of the northernmost records of dinosaur reproductive behaviors. Analysis of the eggshell fragments, adult dinosaur teeth, and fish scales shows that the eggs were laid at the very beginning of spring, benefiting from mild temperatures and increasing food availability. This timing allowed the hatchlings to grow large enough to survive the next winter or migrate southwards with adult dinosaurs.

Summary: The study revised the systematic status of ancient neurocrania found in the Autun Basin and the Bourbon l'Archambault Basin in France using new methods, proposing a new systematic classification and revealing their hidden anatomy. Through comparative analysis, an evolutionary transition between chondrichthyan groups, particularly in the ethmo-orbital region, was identified.
