Biomechanical analyses of pterygotid sea scorpion chelicerae uncover predatory specialisation within eurypterids
Introduction Feeding toolkits of proposed fossil predators are typically explored through functional morphology, often with comparison to modern analogues. In the last two decades, there has been a focus on modelling animals using two-dimensional (2D) and three-dimensional (3D) biomechanical analyses, including finite element analyses (FEA) (Ross, 2005; Rayfield, 2007; van Heteren et al., 2021; Rowe & Snively, 2022).
A European giant: a large spinosaurid (Dinosauria: Theropoda) from the Vectis Formation (Wealden Group, Early Cretaceous), UK
Additional Information and Declarations Competing Interests The authors declare there are no competing interests. Author Contributions Chris T. Barker conceived and designed the experiments, performed the experiments, analyzed the data, prepared figures and/or tables, authored or reviewed drafts of the article, and approved the final draft. Jeremy A.F. Lockwood conceived and designed the experiments, analyzed the data, authored or reviewed drafts of the article, and approved the final draft.
The phylogenetic nomenclature of ornithischian dinosaurs
Protocol In order to be formally established under the ICPN, clade names must comply especially with the provisions of Articles 7 and 9–11 of the Code (ICPN: Art. 7.2d). These Articles are fully followed here. The entries, provided in ‘Phylogenetic nomenclature of ornithischian clades’ below, partly follow the scheme used in Phylonyms (de Queiroz, Cantino & Gauthier, 2020); they include the following sub-sections: ‘Definition’, ‘Reference phylogeny’, ‘Composition’, ‘Synonyms’, and ‘Comments’.
Bite force estimates in juvenile Tyrannosaurus rex based on simulated puncture marks
Discussion Estimated bite forces of adult T. rex have yielded a wide range of results, and our study provides the first experimentally derived juvenile bite force estimates to contextualize the assessment of adult bite force estimates. Modelled muscle volume estimates for adult T. rex bite correspond to forces between 8,526 and 34,522 N (Barrett & Rayfield, 2006; Bates & Falkingham, 2012). However, estimates incorporating likely muscle fiber length produced results over 64,000 N for adult T.
A new brachylophosaurin (Dinosauria: Hadrosauridae) from the Upper Cretaceous Menefee Formation of New Mexico
Introduction The Menefee Formation represents one of the most promising frontiers for exploring the early evolution of major dinosaur groups in Laramidia, the Upper Cretaceous landmass consisting of Mexico, the western United States, western Canada, and Alaska (Fig. 1 in Sampson et al. (2010)).
A new tyrannosaurid (Dinosauria: Theropoda) from the Upper Cretaceous Menefee Formation of New Mexico
UMNH VP 28348 was collected at a single locality; as there is no duplication, morphological inconsistency, or size incompatibility among the identifiable elements, all bones collected from the site are regarded as pertaining to a single tyrannosaurid individual. All elements were collected as float in 2012. A test excavation that same year and subsequent visits in 2013 and 2018 did not reveal additional bones at the site.
A new nodosaurid ankylosaur (Dinosauria: Thyreophora) from the Upper Cretaceous Menefee Formation of New Mexico
Western Science Center 16505 consists of small fragments of a dorsal rib, six complete or partial identifiable osteoderms (WSC 16505.1–WSC 16505.6), and fragments of additional osteoderms. Although this specimen includes fewer osteoderms than the two referred specimens, UMNH VP 28350 and UMNH VP 28351 (Fig.
