Abstract

The European fossil record of crocodylomorphs during the Cretaceous is indubitably skewed towards the lowermost and uppermost strata. Neosuchian remains from the Aptian–Albian interval are exceptionally rare in marine deposits globally. Yet, they potentially hold important information for understanding the phylogenetic interrelationships of several neosuchian lineages. Here, we assign a single squamosal to cf. Pholidosauridae and some postcranial elements to Neosuchia indet. from Aptian and Albian marine deposits in southeastern France. Although it is presently impossible to ascertain the continental versus marine origin of the specimens, their rare occurrence calls for future investigations of the diversity and interrelationships of neosuchians during the mid-Cretaceous.

法国东南部Aptian-Albian海相沉积物中首次发现新苏世遗迹

欧洲白垩纪鳄鱼形动物的化石记录无疑偏向于最下层和最上层的地层。在全球海相沉积物中，来自阿普提亚-阿尔比安区间的新苏世遗迹极为罕见。然而，它们可能为理解几个新古猿谱系的系统发育相互关系提供了重要的信息。在这里，我们将一个单一的鳞片分配给cf. Pholidosauridae，并将一些颅后元素分配给Neosuchia indet。来自法国东南部的阿普tian和Albian海洋沉积物。虽然目前还不可能确定这些标本的大陆和海洋起源，但它们的罕见出现要求对白垩纪中期新龙目的多样性和相互关系进行进一步的研究。

期刊介绍： The Proceedings of the Geologists'' Association is an international geoscience journal that was founded in 1859 and publishes research and review papers on all aspects of Earth Science. In particular, papers will focus on the geology of northwestern Europe and the Mediterranean, including both the onshore and offshore record. Following a long tradition, the PGA will focus on: i) a range of article types (see below) on topics of wide relevance to Earth Sciences ii) papers on aspects of Earth Science that have societal relevance including geoconservation and Earth management, iii) papers on palaeoenvironments and palaeontology of the Mesozoic and Cenozoic, iv) papers on aspects of Quaternary geology and climate change, and v) papers on the history of geology with particular reference to individuals that have shaped the subject. These topics will also steer the content of the themes of the Special Issues that are published in the PGA.
