拉斯拉切里亚斯剖面的上部显示了一个异常完整的上莫斯科阶（Myachkovsky）和卡西莫阶（Krevyakinsky-Khamovnichesky）地层序列，在整个序列中从许多层中产生了Fusulinacean有孔虫。除了已经在另一篇论文中描述的高级fusulinellins和原始schwagerinins外，本工作完成了对fusulinacea动物群的研究，并描述了额外的fusulinids，schubertellinids和ozawainellids。
本节所研究部分的镰刀纲动物为识别三个生物带提供了依据，Fusulinella带、Protriticites带和Montiparus带，它们允许将Las Llacerias地层与莫斯科盆地和顿涅茨克盆地进行对比。一个早期的Schwagerinid物种介于Protriticites和Triticites之间，发现于剖面的顶部附近，指出该剖面的最上部与北美的米苏利亚基底的相关性。先前在坎塔布里亚山脉的这一部分和其他部分进行的一些关于孢子和镰孢纲动物的联合研究，为与西欧地层规模的初步对比提供了线索。
The upper part of the Las Llacerias section shows an exceptionally complete sequence of Upper Moscovian (Myachkovsky) and Kasimovian (Krevyakinsky-Khamovnichesky) strata which yielded fusulinacean foraminifera from numerous beds throughout the succession. In addition to the advanced fusulinellins and primitive schwagerinins described already in a separate paper, the present work completes the study of the fusulinacean fauna with the description of additional fusulinids, schubertellinids, and ozawainellids.
The fusulinaceans of the studied part of this section provide a basis for recognizing three biozones, i.e., the Fusulinella, Protriticites and Montiparus Zones, and they allow a correlation of the Las Llacerias strata with the Moscow Basin and the Donets Basin. An early schwagerinid species intermediate between Protriticites and Triticites, found near the top of the section, points to a correlation of the uppermost part of the section with the basal Missourian of North America. Some combined studies on spores and fusulinaceans, carried out previously in this and other Cantabrian Mountains sections, give clues for a tentative correlation with the Western Europe stratigraphic scale.
