Abstract

The carbon stable isotope composition (δ13C) of tooth enamel in mosasaurid squa-mates reflects aspects of their diet and diving behaviour. Here we present new δ13C data for such marine squamates from the Maastrichtian of Denmark and compare these with results obtained in previous studies from the lower-latitude type area of the Maastrichtian Stage (latest Cretaceous; 72.1–66.0 Ma) in the south-east Nether-lands and north-east Belgium. For the Danish samples, there is a weak correlation between mosasaur body size and δ13C values, with larger-sized taxa having lower δ13C values, comparable to what has previously been observed for mosasaurs from the Maastrichtian type area.

马尾藻配偶牙釉质的碳稳定同位素组成（δ13C）反映了它们的饮食和潜水行为。在这里，我们提供了来自丹麦马斯特里赫特阶的这些海洋小队的新的δ13C数据，并将这些数据与之前在荷兰东南部和比利时东北部马斯特里赫特期（白垩纪晚期；72.1–66.0 Ma）低纬度型区域的研究结果进行了比较。对于丹麦样本，摩萨龙的体型和δ13C值之间的相关性较弱，较大的分类群具有较低的δ13C，与之前在马斯特里赫特类型地区观察到的摩萨龙相当。
