Abstract

This paper documents the occurrence of Skolithos linearis, Planolites beverleyensis, and Thalassinoides isp. in the Cárdenas Formation (Late Cretaceous), southeastern San Luis Potosí, central Mexico. This is the second record of S. linearis for this lithological unit, while P. beverleyensis and Thalassinoides isp. are documented for the very first time in this formation. The ichnoassemblage is referred to the Cruziana Ichnofacies which, in concert with associated invertebrate body fossils (Exogyra costata), suggest a shoreface setting with moderate- to low-energy conditions and episodic storms.

墨西哥中部圣路易斯波托西Potrero del Carnero的Cárdenas组（白垩纪晚期，马斯特里赫特阶）遗迹化石的古环境意义

本文记录了线性Skolithos linear, Planolites beverleyensis和Thalassinoides isp的出现。在墨西哥中部圣路易斯Potosí东南部的Cárdenas组(晚白垩世)。这是继P. beverleyensis和P. Thalassinoides之后，在该岩性单元中第二次记录到S. linearis。都是第一次记录在这个信息中。该鱼群组合被称为Cruziana鱼群相，该鱼群相与相关的无脊椎动物化石(Exogyra costata)相一致，表明一个具有中低能量条件和间歇性风暴的滨面环境。

期刊介绍： The Boletín de la Sociedad Geológica Mexicana is a completely free-access electronic journal published semi-annually that publishes papers and technical notes with its main objective to contribute to an understanding of the geology of Mexico, of its neighbor areas, and of geologically similar areas anywhere on Earth’s crust. Geology has no boundaries so we may publish papers on any area of knowledge that is interesting to our readers. We also favor the publication of papers on relatively unfamiliar subjects and objectives in mainstream journals, e.g., papers devoted to new methodologies or their improvement, and areas of knowledge that in the past had relatively little attention paid them in Mexican journals, such as urban geology, water management, environmental geology, and ore deposits, among others. Mexico is a land of volcanos, earthquakes, vast resources in minerals and petroleum, and a shortage of water. Consequently, these topics should certainly be of major interest to our readers, our Society, and society in general. Furthermore, the Boletín has been published since 1904; that makes it one of the oldest scientific journals currently active in Mexico and, most notably, its entire contents, from the first issue on, are available online.
