Environmental controls and distribution of Late Jurassic neoselachians from the Iberian Basin (NE Spain) in the European context

化石新塞拉亚人.主要是通过它们的牙齿来识别的，因此，新塞拉契亚人的进化和生态学仍然是模糊的。晚侏罗世新塞拉纪的多样性知识是我们了解其早期演化历史和辐射的基础。尽管不同的新塞拉纪动物群在侏罗纪的发展，古生物的特殊性的类群一般被忽视。该项目的重点是来自西班牙东北部的晚侏罗世新塞拉契亚人。从平台内的一系列相的广泛采样将允许评估盆地内的新塞拉纪鲨鱼和鳐的古环境分布，但也重建欧洲晚侏罗世新塞拉纪动物群和disciminate特提斯和北方影响之间的动物群交流。地球化学示踪分析…对一系列不同相和年龄的牙齿进行的研究将有助于建立地层和古生态框架。结果将与其他晚侏罗世新塞拉纪组合进行比较，并重建总体多样性模式，这反过来又可用作现代新塞拉纪分布的代表。

Fossil neoselachians... are primarily recognized by their teeth and, consequently, the evolution and ecology of neoselachians through time is still obscure. Knowledge of Late Jurassic neoselachians diversity is fundamental to our understanding of their early evolutionary history and radiation. Despite the development of diverse neoselachian faunas within the Jurassic, the palaeonvironmental specificity of the taxa has generally been ignored. The project focuses on Late Jurassic neoselachians from NE Spain. Extensive sampling from a range of facies within the platform will allow to asses the palaeoenvironmental distribution of neoselachian sharks and rays within the basin but also to reconstruct faunal exchanges between European Late Jurassic neoselachian faunas and disciminate Tethyal and boreal influences. Geochemical tracer analyses... performed on selected teeth from a range of different facies and ages will help establishing a stratigraphic and palaeoecological framework. The results will be compared to other Late Jurassic neoselachian assemblages and general diversity patterns will be reconstructed, which, in turn, can be used as proxies for modern neoselachian distribution.
