风神龙族
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与巴西。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]
