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

量化已灭绝类群的吻部敏感度的尝试已被证明在与雷克斯暴龙密切相关的恐龙中是成功的。然而，重onychine类群的情况尚不确定，重onychine类群与水生觅食和鳄鱼般的生态和行为有关。该项目将研究和描述来自怀特岛布莱特斯通湾的特殊和独特的重onychine恐龙材料。通过应用和进一步发展先进的三维微计算机断层成像（uCT）成像和计算方法，用于矿化和石化组织/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，骨骼解剖，脑解剖，眼睛和鼻腔位置的数据，以阐明分类群的生活习惯，并评估水生习惯的可能性。通过更好地了解这个分类单元，与已知的系统发育，学生将能够确定一个独特的神秘和魅力的英国兽脚亚目动物的性格习得和行为。这个多学科项目利用了工程、philip Schneider （uCT， u-VIS x射线成像中心学术主任）和生物科学、Claire Clarkin（骨骼解剖学）和Neil Gostling（古生物学和进化）方面的专业知识，它将重新振兴整个大学的本科教学，并建立在大学与怀特岛恐龙岛（www.dinosaurisle.com）之间的谅解备忘录的基础上。提供免费进入预备实验室和其他发现的标本。uCT技术的使用意味着化石标本的非破坏性采样，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灵敏度。

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.
