The order Intejocerida is an enigmatic, short-lived cephalopod taxon known previously only from Early–Middle Ordovician beds of Siberia and the United States. Here we report a new genus,Cabaneroceras, and a new species,C. aznari, from Middle Ordovician strata of central Spain. This finding widens the paleogeographic range of the order toward high-paleolatitudinal areas of peri-Gondwana. A curved conch, characteristic for the new genus, was previously unknown from members of the Intejocerida.UUID:http://zoobank.org/21f0a09c-5265-4d29-824b-6b105d36b791

西班牙中部达里维利安(中奥陶世)地层的非古热带环纹头足类动物的首次记录

Intejocerida 目是一种神秘的、短命的头足类动物分类群,以前只在西伯利亚和美国的早中期奥陶纪地层中发现。在这里,我们报告了一个新属,赤霞珠,和一个新物种,C. aznari,来自西班牙中部的中奥陶世地层。这一发现扩大了该命令的古地理范围,朝向冈瓦纳周边的高古纬度地区。弯曲的海螺,新属的特征,以前在 Intejocerida.UUID 的成员中是未知的:http://zoobank.org/21f0a09c-5265-4d29-824b-6b105d36b791
