遗留龙属
遗留龙(属名:Oblitosaurus,意为“遗留的蜥蜴”)是西班牙晚侏罗世大主教村组发现的一属直姆指龙类鸟脚类恐龙。模式种是布氏遗留龙(Oblitosaurus bunnueli)。[1]
发现与命名
遗留龙正模标本由一颗齿骨牙齿(CPT-1440)、一个来自左手的爪子(CPT-1444)及一条近乎完整的左后肢(MAP-8290至MAP-8299)组成。来自同一区域的大型脚印也可能属于该分类单元。[1]
这些骨骼残骸于2023年鉴定为鸟脚类新属新种布氏遗留龙(Oblitosaurus bunnueli)。属名取自拉丁语oblitus(意为“遗留的”或“被遗忘的”)及希腊语sauros(意为“蜥蜴”)以形容其化石在发现地的发现时间之晚。种名致敬西班牙电影制作人路易斯·布努埃尔(Luis Buñuel)。[1]
分类
Sánchez-Fenollosa等人(2023年)在系统发育分析中发现遗留龙是种原始直姆指龙类兼龙爪龙的姐妹群,形成了一个貌似未在北美出现过的欧洲直姆指龙类演化支。此外,该分析还表明弯龙是一个单系群,并首次显示所有归入弯龙的物种皆处在同一演化支中。系统发育分析结果如以下分支图所示:[1]

古生态学
除遗留龙外,大主教村组还出土了许多其它动物的遗骸,包括一种类似弯龙、仅有椎骨发现的不同鸟脚类、[2]一种类似锐龙的剑龙类[3]及多种蜥脚类如图里亚龙、洛西亚龙、加尔瓦龙和阿拉果龙。[4][5][6][7]
