Abstract

A new member of Spinosauridae from the Enciso Group (uppermost Barremian–lower Aptian) from Igea (La Rioja, Spain) is here erected on the basis of axial, pelvic girdle, and hindlimb elements that exhibit a unique combination of characters. Riojavenatrix lacustris gen. et sp. nov. is one of the latest Iberian and European spinosaurid taxa. It retains a triangular pubic boot, like the megalosaurids, and a medial condyle of the femur that shows a transitional stage between the anteroposteriorly oriented long axis of non-spinosaurid theropods and the posteromedially oriented long axis of Spinosauridae. The spinosaurid record of Iberia ranges from the late Hauterivian–early Barremian to the latest Barremian–early Aptian so far, and both the oldest and the most recent evidence comes from the Cameros Basin, where spinosaurid remains are especially abundant in the Barremian deposits. A review of the spinosaurid record has allowed us to dismiss the presence of the genus Baryonyx from Iberia; hence, only Camarillasaurus, Iberospinus, Protathlitis, Riojavenatrix gen. nov., and Vallibonavenatrix are considered to be present in the Early Cretaceous of Iberia. According to this study, Riojavenatrix is one of the youngest baryonychines in the fossil record.
增加欧洲的兽脚类记录:卡梅罗斯盆地(西班牙拉里奥哈)恩西索组新发现的基干棘龙。进化意义和古生物多样性
本文基于伊赫亚(西班牙拉里奥哈)恩西索组(上巴利米亚统-下奥普梯统)的一个棘龙科新成员的轴部、骨盆腰部和后肢的特征组合,将其竖立起来。Riojavenatrix lacustris gen.与巨龙类一样,它保留了三角形的耻骨靴,股骨内侧髁显示出非棘龙科兽脚类的前胸向长轴与棘龙科的后内向长轴之间的过渡阶段。迄今为止,伊比利亚的棘龙类记录范围从豪特里维世晚期到巴雷姆世早期,再到巴雷姆世晚期到始新世早期,最古老和最新的证据都来自卡梅罗斯盆地,那里的巴雷姆世沉积中棘龙类遗骸尤其丰富。通过对棘龙类记录的回顾,我们认为伊比利亚早白垩世只存在Baryonyx属;因此,我们认为伊比利亚早白垩世只存在Camarillasaurus、Iberospinus、Protathlitis、Riojavenatrix gen.nov.和Vallibonavenatrix。根据这项研究,Riojavenatrix 是化石记录中最年轻的重棘皮动物之一。
