酋长龙属学名Loncosaurus)是鸟脚亚目恐龙的一,化石发现于阿根廷圣克鲁斯省,地质年代为上白垩纪模式种阿根廷酋长龙L. argentinus),是由阿根廷古生物学家佛罗伦天奴·阿米希诺(Florentino Ameghino)描述、命名,目前被认为是疑名。酋长龙的学名意思并不明确,有可能是阿劳坎语的“酋长”或希腊文的“长矛”,中文译名则使用了前者的意思[1]。由于酋长龙曾长时间被误认为是属于兽脚亚目,所以有关牠的资料经常存在矛盾。

历史

佛罗伦天奴·阿米希诺在1898年[2][3][4][5]或1899年[6][7][8][9][10]叙述、命名了酋长龙,化石包含一根股骨近端(编号MACN-1629)及牙齿,发现于圣克鲁斯省的Cardiel地层或Matasiete地层[9]

无论是哪一种说法,他都认为酋长龙是属于肉食性斑龙科,而休尼(Friedrich von Huene)也支持这个说法[11]。后来的研究则指酋长龙是属于虚骨龙科[12],但当时未分类的小型肉食性恐龙,多被分类到虚骨龙科。因为牙齿化石类似肉食性动物,而造成这种鉴定结果。

经过数十年后,Ralph Molnar重新研究这些化石[13]。他发现那牙齿不是来自于该股骨的同一动物个体。他更指出该股骨是属于棱齿龙类。后来的研究发现并没有不同的结果,只有股骨的长度数据不同,以及酋长龙是属于禽龙类而非棱齿龙类[9]。目前酋长龙被分类为鸟脚下目的分类不明属[9]、或禽龙类[3][4]。奇怪的是有人指出酋长龙是属于锐颌龙属,但却没有解释原因,这个分类法后来没有被接纳[14]

古生物学

罗多尔夫·科里亚(Rodolfo Coria)估计酋长龙长约5米[9]。这个体型在鸟脚下目是属于小至中等动物,所以酋长龙有可能是行动轻盈的双足草食性恐龙[4]
