发现与命名

[编辑]
角鳄龙(后)与滨猎龙(前)的已知材料

2021年,模式种冥鹭角鳄龙C. inferodios)由克里斯·巴克(Chris Barker)、德恩·耐许英语Darren Naish(Darren Naish)、大卫·宏恩(David Hone)及其他古生物学家组组成的团队命名并描述。种名意为“地狱苍鹭”,指研究团队所推测的食鱼性生态栖位。[1]

正模标本IWCMS英语Dinosaur Isle 2014.95.5(前颌骨体)、IWCMS 2021.30(前颌骨后段的碎片)和IWCMS 2014.95.1-3(接近完整的脑壳)组成,三者皆发现于威塞克斯组奇尔顿岭英语Chilton Chine的岩石中,并在恐龙岛博物馆英语Dinosaur Isle收藏。归入本属材料包括单个右眶后骨(IWCMS 2014.95.4)。[1]

描述

根据Dan Folkes2021发表的描述论文中的骨骼重建,角鳄龙身长估计为8.5米(27英尺)。[1]

种系发生学

[编辑]

描述者将该属作为新建立的演化支――角鳄龙族(Ceratosuchopsini)的成员,且与似鳄龙及同时期的滨猎龙关系较近。[1][2]

古生态学

[编辑]

角鳄龙生存于威塞克斯组干燥的地中海栖息地,那里的河流是河岸带的起源。[3][4]与大多数棘龙科一样,它会以该地区的中小型水生及陆生动物为食。[5][6][7]
