项目摘要
Europe was mainly covered by epicontinental seas during the Upper Jurassic and Lower Cretaceous, so that terrestrial faunas were mainly restricted to several larger islands. Nevertheless, recent biogeographic analyses indicate that Europe represented an important "turntable" of terrestrial faunas between Asia, Africa, and North America at that time. One of the important islands in the Lower Cretaceous was Iberia, which included most of present day Spain and Portugal. Lower Cretaceous dinosaurs from Spain have become better known in the past 30 years, and especially ornithischian and sauropod dinosaurs have already yielded important data for our understanding of European dinosaur faunas of that time and their biogeographic relationships. However, theropod dinosaurs are much more poorly known; apart from the exceptionally preserved ornithomimosaur Pelecanimimus and the carcharodontosaur Concavenator from the laminated limestones of Las Hoyas, only one further taxon, Camarillasaurus cirugedae, has recently been described from the Barremian Camarillas Formation. This latter taxon is based on a fragmentary postcranial skeleton and was identified as a basal ceratosaur, with important implications for the evolution and diversity of this clade. However, a preliminary study of this material by the applicant highlighted several problems with the original interpretations of the remains and the identification as a ceratosaur. Furthermore, a visit to the site, from where the original materials were recovered by surface collection, demonstrated that there is potential to recover more material of this taxon. The objectives of the current project are thus a complete excavation of the type locality of Camarillasaurus and a revision of the anatomy and phylogenetic position of this taxon, based on both the original remains and newly discovered elements.This will lead to a better understanding of its importance for our knowledge of Early Cretaceous European dinosaur faunas and their biogeographic relationships.
上侏罗世和下白垩世期间,欧洲主要被陆缘海覆盖,因此陆地动物群主要局限于几个较大的岛屿。然而,最近的生物地理学分析表明,欧洲代表了当时亚洲、非洲和北美之间陆地动物群的重要“转盘”。下白垩纪的重要岛屿之一是伊比利亚岛,其中包括今天西班牙和葡萄牙的大部分地区。来自西班牙的下白垩纪恐龙在过去 30 年中更加为人所知,尤其是鸟臀目和蜥脚类恐龙,已经为我们了解当时欧洲恐龙动物区系及其生物地理关系提供了重要数据。然而,兽脚类恐龙却鲜为人知。除了拉斯霍亚斯层状石灰岩中保存完好的拟鸟龙 Pelecanimimus 和鲨齿龙 Concavenator 之外,最近在巴雷姆卡玛利拉斯地层中仅描述了另一种分类群:Camarillasaurus cirugedae。后一个分类单元基于破碎的颅后骨骼,被鉴定为基础角鼻龙,对该分支的进化和多样性具有重要意义。然而,申请人对这些材料的初步研究突显了对遗骸的原始解释和角鼻龙鉴定的几个问题。此外,对通过表面收集回收原始材料的地点的访问表明,有可能回收更多该分类单元的材料。因此,当前项目的目标是根据原始遗骸和新发现的元素,全面挖掘隐密龙的模式产地,并修订该分类单元的解剖学和系统发育位置。这将有助于我们更好地了解其对于我们了解早白垩世欧洲恐龙动物群及其生物地理关系的重要性。
