A Description of new baryonychine material and assessment of trigeminal (palaeo) neuroanatomy in extinct and extant archosaurs

在灭绝的分类群中量化吻敏感性的尝试在与霸王龙雷克斯密切相关的恐龙中证明是成功的。然而，这是不确定的Baryonychine组，这一直与水生觅食和鳄鱼一样的生态和行为。该项目将研究和描述来自怀特岛的斯通湾的特殊和独特的重爪龙材料。通过应用和进一步开发先进的3D微计算机断层扫描（uCT）成像和计算方法，用于矿化和矿化组织/材料的最先进的定量形态测量，博士生将可视化和定量评估和解释来自骨密度的数据，骨骼解剖学，大脑解剖学，眼睛和鼻腔的位置，以阐明分类群的生活习惯，并评估水生习性的可能性。通过更好地了解这个分类群，与已知的遗传学有关，学生将能够确定一个独特的神秘和魅力的英国兽脚亚目恐龙的性格获得和行为。（uCT，学术主任u-VIS X射线成像中心）和生物科学，Claire Clarkin（骨骼解剖学）和Neil Gostling（古生物学与进化）将重振整个大学的本科教学，并建立在大学与怀特岛恐龙岛（www.example.com）之间的谅解备忘www.dinosaurisle.com录基础上，提供免费访问准备实验室和其他标本。uCT技术的使用意味着化石标本是非破坏性采样的，使我们能够以无与伦比的方式描述1.27亿年前恐龙的神经解剖学和敏感性。

Attempts to quantify rostral sensitivity in extinct taxa have proven successful in dinosaurs that are closely related to Tyrannosaurus rex. However, this is undetermined for the Baryonychine group, which has been associated with aquatic foraging and crocodilian-like ecology and behaviour. This project will examine and describe the exceptional and unique Baryonychine dinosaur material from Brightstone Bay, Isle of Wight. By applying and further developing advanced 3D micro-computed tomographic (uCT) imaging and computational approaches for state-of-the art quantitative morphometry for mineralised and fossilised tissues/materials, the PhD student will visualise and quantitatively evaluate and interpret data derived from bone density, and skeletal anatomy, brain anatomy, the position of eyes and nasal passages, to elucidate the life habits of the taxon, and assess the likelihood of aquatic habits. By better understanding this taxon, in relation to the known phylogeny, the student will be able to determine character acquisition and behaviours in a unique enigmatic and charismatic British theropod.This multidisciplinary project draws on expertise in Engineering, Philipp Schneider (uCT, Academic Director u-VIS X-ray Imaging Centre) and Biological Sciences, Claire Clarkin (Bone Anatomy) and Neil Gostling (Palaeontology and Evolution) it will reinvigorate undergraduate teaching across the University and builds upon the MoU between the University and Dinosaur Isle (www.dinosaurisle.com) on the Isle of Wight, providing free access to the prep-laboratory and to other specimens that come to light. The use of uCT technology means that fossil specimens are non-destructively sampled, allowing us unparalleled means of describing the neuroanatomy and sensitivity in a 127-million-year-old dinosaur.
