A New Large-Bodied Oviraptorosaurian Theropod Dinosaur from the Latest Cretaceous of Western North America
Phylogenetic analysis indicates that Anzu is most closely related to Caenagnathus collinsi, a taxon that is definitively known only from a mandible from the Campanian Dinosaur Park Formation of Alberta, and the problematic oviraptorosaurs Microvenator and Gigantoraptor are recovered as basal caenagnaths, as has previously been suggested.

The evolutionary continuum of limb function from early theropods to birds
It is emphasised that many false dichotomies or categories have been applied to theropod form and function, and sometimes, these impede research progress, and a combination of techniques that emphasises integration of neontological and palaeontological evidence and quantitative assessment of limb function cautiously applied with validated techniques and sensitivity analysis of unknown variables are needed.

Fossil fishes from a lag deposit within the Upper Cretaceous Mancos Shale in New Mexico, USA, with comments on correlative Turonian–Coniacian time-transgressive lags in the Western Interior Seaway of North America
Abstract A lag deposit between the Tocito Sandstone and Mulatto Tongue of the Upper Cretaceous Mancos Shale in Sandoval County, New Mexico, USA, contains a fossil assemblage of late Turonian–earlyExpand
A new two-fingered dinosaur sheds light on the radiation of Oviraptorosauria
Variation in forelimb length and manus morphology provides another example of niche partitioning in oviraptorosaurs, which may have made possible their incredible diversity in the latest Cretaceous of Asia. Expand
Forelimbs of the theropod dinosaur Dilophosaurus wetherilli: Range of motion, influence of paleopathology and soft tissues, and description of a distal carpal bone
Experiments on American alligator cadavers show that ROM exhibits limited intraspecific variation and is greater in the fullyfleshed elbow than skeletal manipulation suggests, and this work adjusts the results of the bare-bones manipulations to account for the known influence of soft tissues.

Spatiotemporal Distributions of Non-ophidian Ophidiomorphs, With Implications for Their Origin, Radiation, and Extinction
Non-ophidian ophidiomorphs, colloquially referred to as ‘dolichosaurs,’ are small-bodied aquatic lizards that lived in shallow seaways, rivers, and reef environments during the Late Cretaceous.Expand
“Keep your feet on the ground”: Simulated range of motion and hind foot posture of sauropods-a case study of the Middle Jurassic Rhoetosaurus brownei
  • 2019
“Keep your feet on the ground”: Simulated range of motion and hind foot posture of the Middle Jurassic sauropod Rhoetosaurus brownei and its implications for sauropod biology
It is shown that Rhoetosaurus brownei was capable of significant digital mobility at the osteological metatarsophalangeal and distal interphalangeal joints, ultimately resulting in a functionally plantigrade pes, which may have arisen during the Early to Middle Jurassic. Expand
Morphological and phylogenetic aspects of the dentition of Megacephalosaurus eulerti, a pliosaurid from the Turonian of Kansas, USA, with remarks on the cranial anatomy of the taxon
Abstract Megacephalosaurus eulerti is a large macropredatory plesiosaur representing one of the last members of the diverse pliosaurid clade Brachaucheninae. The taxon was established upon a nearlyExpand
