This individual, NHMM 2012 072, was recovered from the upper Lixhe 3 Member (Gulpen Formation, upper Maastrichtian) near Maastricht, the Netherlands. In all likelihood, it was bitten in the snout by a large, possibly conspecific mosasaur – and survived this attack. The specimen described here is among the very few with clear and unambiguous evidence of (very likely intraspecific) agonistic interactions amongst mosasaurs. Desp狮心

0部分另外复原内容：应该是CCMGE的发现过程 完整的沧龙骨骼是惊人的少见的。这些发现包括乌克兰东部坎帕尼亚矿床中1901年的Prognathodon lutugini Yakovlev的部分骨骼（Yakovlev 1905；Grigoriev2013）；第二次世界大战期间丢失的马斯特里赫特地区Rasstrigin（伏尔加格勒地区的右岸部分）（Lavrentiev1930；Yarkov1993）的部分强变形骨骼；来自马斯特里赫特阶地区霍夫曼沧龙的部分化石来自Penza149的晚白垩世（萨拉托夫地区的右岸部分），Bayarunas（1914年）将其定义为Mosasuru狮心...

5Incremental stages of major evolutionary transitions within a single animal lineage are rarely observed in the fossil record. However, the extraordinarily complete sequence of well preserved material spanning the 27-Myr existence of the marine squamate subfamily Mosasaurinae provides a unique exception. By comparison with extant and extinct analogs, the tail morphology of four mosasaurine genera is examined, revealing a pattern of evolution that begins with the generalized varanoid anatomy and culminates in a high-aspect-ratio fin, similar to that of sharks. However, unlike the epicercal cauda狮心...

2Mosasauroids are squamates secondarily adapted to an aquatic life that dominated the sea during the Late Cretaceous. Mosasauroids display distinct types of morphologies illustrating steps in the adaptation of this lineage to increasing obligatory habits. Hydropelvic mosasauroids (sensu Caldwell & Palci) were the most highly adapted to an open-sea environment. Contrary to plesiopelvic forms, they are considered to have relied on a hydrodynamic, rather than hydrostatic buoyancy and body trim control strategies. This led previous authors to consider that these taxa would favour bone lightenin狮心...

我就搞不懂了，吧友为什么认为沧龙不如虎鲸？ 1.体型对比 大型沧龙和虎鲸体型上面差不多或者完全压制 经过大范围实测 最小的虎鲸种群 南极C 雌性平均5.2米 最大5.8（论文提出比常规母虎鲸短0.6米 所以母虎鲸典型体长 5.8米） 雄性平均5.6米 最大6.1 （论文提出比常规公虎鲸短1.1米 所以公虎鲸的典型体长6.7米） For the 252 individual whales we photographed, images of 220 were of sufficient quality to measure accurately (Table 2). These included 64 males, 33 adult females (with calves), 26 calve共 8 张狮心...
