摘要

摘要Algorachelus peregrinus是月桂岛已知的冠群Pleurodira中最古老的代表。这两种类型的地点是阿尔戈拉,位于西班牙中部,在上塞诺曼尼亚时期沉积的水平。这个城镇最近进行了一次新的挖掘工作。因此,发现了大量的褐藻材料。几个完整的壳,以及许多部分甲壳和质,呈现在这里。大量的残骸使我们能够分析出这种沿海形式的一些贝壳部分或完全脱落的一般模式。对这些遗骸的分析不仅显示了几种病理,而且还提高了对远游褐藻的解剖学和种内变异性的认识。这一新信息允许对来自中东和北美的其他格诺曼尼亚形式的Bothremydidae进行修订。因此,在这些地区发现了Algorachelusis,在巴勒斯坦的早期或中诺曼尼亚语中,新组合为Algorachelus parvus,在犹他州的最上层诺曼尼亚语中,新组合为Algorachelus tibert。因此,认识到一个相对快速和广泛分布的地理分散事件,对应于迄今为止确定的从冈瓦纳到劳亚的最古老的Pleurodira谱系的分散事件。

New information on the Cenomanian bothremydid turtle Algorachelus based on new, well-preserved material from Spain
Abstract. Algorachelus peregrinus is the oldest representative of the crown group Pleurodira known in Laurasia. The type locality of this bothremydid is Algora, situated in central Spain, at levels deposited during the uppermost middle–lowermost upper Cenomanian. A new excavation was recently carried out in this town. As a result, abundant material of Algorachelus peregrinus has been found. Several complete shells, as well as numerous partial carapaces and plastra, are presented here. The abundance of remains allows the analysis of the general patterns by which some of the shells of this littoral form were partially or totally disarticulated. The analysis of these remains not only shows several pathologies but also improves the knowledge about the anatomy and intraspecific variability of Algorachelus peregrinus. This new information allows the revision of other Cenomanian forms of Bothremydidae, both from the Middle East and from North America. Thus, Algorachelus is identified in these regions, being represented in the early or middle Cenomanian of Palestine by the new combination Algorachelus parvus, and in the uppermost Cenomanian of Utah by the new combination Algorachelus tibert. Therefore, a relatively fast and widely distributed geographic dispersion event is recognized, corresponding to the oldest dispersal event so far identified for a lineage of Pleurodira from Gondwana to Laurasia.

期刊介绍: Fossil Record (FR) is the palaeontological journal of the Museum für Naturkunde Berlin. This journal was founded in 1998 under the name Mitteilungen aus dem Museum für Naturkunde Berlin, Geowissenschaftliche Reihe and appears with two issues each year. Fossil Record publishes original papers in all areas of palaeontology including the taxonomy and systematics of fossil organisms, biostratigraphy, palaeoecology, and evolution. All taxonomic groups are treated, including invertebrates, microfossils, plants, and vertebrates.
