摘要

传统上，西伯利亚的克劳地那形态化石被认为是在特定的水动力条件下插入另一个Anabarites测试的一种地层学模式。在西伯利亚的Kessyusa群和同时期地层中，可伸缩的圆锥形试验簇是普遍存在的，并不是所有这些都可以很容易地解释为简单的机械堆积的结果。这些星团中的任何一个是否真的代表了云状结构的生命关联还有待证实。

Sesgo tafonómico en los datos de distribución de Cloudina en Siberia

Cloudina -morph fossils in Siberia have been traditionally regarded as a taphonomic mode of Anabarites tests inserted one into another under specific hydrodynamic conditions. Clusters of telescoped conical tests are ubiquitous in the Kessyusa Group and coeval strata across Siberia and not all of them can be easily interpreted as a result of simple mechanical stacking. It remains to be confirmed whether any of these clusters actually represents a life association of a Cloudina -morph structure.

期刊介绍： Since 1945 Estudios Geologicos publishes original research works, as well as reviews, about any topic on Earth Sciences. Estudios Geologicos is published as one yearly volume, divided into two half-yearly issues. It is edited by the Spanish National Research Council (Consejo Superior de Investigaciones Científicas, CSIC) at the Instituto de Geociencias (CSIC-UCM). Estudios Geologicos provides free access to full-text articles through this electronic edition. Accepted articles appear online as "Forthcoming articles" as soon as the galley proofs have been approved by the authors and the Editor-in-Chief. No changes can be made after online publication.
