风神龙族(Aeolosaurini)或风神龙科(Aeolosauridae),是蜥脚下目泰坦巨龙类的一个演化支,来自白垩纪晚期的阿根廷巴西。Rodrigo M. Santucci和Antonio C. de Arruda-Campos(2011)的系统发育研究认为风神龙冈瓦纳巨龙马萨卡利神龙泛美龙林孔龙属于风神龙族。[1]

体征

编辑

风神龙族以许多尾椎上的共有衍征为特色,例如偏转的椎体、加长的前关节突、神经棘相对椎体前倾。牠们的尾巴在生前时可能因为以上特征而强烈下弯,这可能增强尾股长肌英语Caudofemoralis收缩后腿的力量。[2]一些风神龙族如宽颈龙属奥韦罗龙相对于其他泰坦巨龙类体型较小。[3][4]但像巨风神龙则体型较大。[1]

风神龙族由Franco-Rosas、Salgado、Rosas和Carvalho(2004)定义为:包含里奥内格罗风神龙、弗氏冈瓦纳巨龙在内,但不包含护甲萨尔塔龙斯氏后凹尾龙在内的最大演化支。以下两个演化树根据Santucci和Arruda-Campos(2011)的风神龙族系统发育关系为基础,左边取自Franca等人(2016)、右边取自Silva等人(2019):[1][5][6]
