Abstract

A turtle carapace, identified as Algorachelus cf. peregrina (Pleurodira, Pelomedusoides, Bothremydidae), is reported here from the shallow marine deposits of the Boundary Marls Unit (Utrillas Group), in Estercuel (Teruel Province, northeastern Spain). These levels are identified as deposited during the Lower to Upper Cretaceous transition (late Albian to earliest Cenomanian). This is the oldest record of a bothremydid turtle in Laurasia, documenting that the first dispersal of pelomedusoid turtles from Gondwana to Laurasia occurred earlier than previously identified, most probably in the Early Cretaceous. Pleurodiran turtles always require warm climatic conditions and are mainly freshwater forms. This dispersal was favored by climate change (global warming) that began in the Albian, as well as by the habitat change of the Algorachelus lineage from freshwater to coastal marine environments.

西班牙东北部的一只海龟表明,Pelomedusoides 从冈瓦纳到劳拉西亚的扩散可能发生在早白垩世
本文报告了一只海龟的甲壳,经鉴定为 Algorachelus cf. peregrina(Pleurodira, Pelomedusoides, Bothremydidae),它来自埃斯特奎尔(西班牙东北部特鲁埃尔省)边界泥灰岩单元(乌特里利亚斯组)的浅海沉积层。这些地层被确定为沉积于下白垩世向上古白垩世过渡时期(晚白垩世至早白垩世)。这是劳拉西亚最古老的两栖类海龟记录,证明了侏罗纪海龟首次从冈瓦纳向劳拉西亚扩散的时间早于之前的发现,很可能是在早白垩世。褶纹龟总是需要温暖的气候条件,而且主要是淡水龟类。阿尔卑斯山时期开始的气候变化(全球变暖),以及阿尔戈拉切卢龟系从淡水环境到沿海海洋环境的栖息地变化,都有利于这种扩散。

期刊介绍: Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene. Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of significant new findings. Papers submitted to Cretaceous Research should place the research in a broad context, with emphasis placed towards our better understanding of the Cretaceous, that are therefore of interest to the diverse, international readership of the journal. Full length papers that focus solely on a local theme or area will not be accepted for publication; authors of short communications are encouraged to discuss how their findings are of relevance to the Cretaceous on a broad scale. Research Areas include: • Regional geology • Stratigraphy and palaeontology • Palaeobiology • Palaeobiogeography • Palaeoceanography • Palaeoclimatology • Evolutionary Palaeoecology • Geochronology • Global events.
