Abstract

A glimpse into ancient food storage: Sequestrichnia and associated nucleocave Chondrites from Eocene deep-sea deposits. Acta Palaeontologica Polonica 67 (3): 767–779. The old brickyard Velká nad Veličkou in the Czech Republic offers a unique insight into an Eocene deep-sea ichno assemblage that is dominated by sequestrichnia. Secondary use of such food-stowing was made by the tracemaker of Chondrites intricatus as evidenced by its frequent penetration of the trace fossil Zoophycos brianteus and its occurrence preferentially on the surface of Zoophycos spreiten. Here, the Chondrites tracemaker presumably exploited the nutrient-enriched micro-environment (nucleocave). This close interrelations between Chondrites and Zoophycos support the hypothesis of a sequestrichnial behaviour of the Zoophycos producer. The studied locality also yields Helminthopsis tenuis, Planolites

对古代食物储存的一瞥:始新世深海沉积物中的Sequestrichnia和相关的核孔球粒陨石。古生物学报67(3):767-779。捷克共和国的旧砖厂velk nad veli kou为研究始新世以sequestrichnia为主的深海ichno组合提供了独特的视角。这种食物储存的二次利用是由错综球粒陨石(Chondrites intericatus)的示踪器进行的，它经常渗透到brianteus Zoophycos的痕迹化石中，并优先出现在spreiten Zoophycos的表面。在这里，球粒陨石示踪器可能利用了营养丰富的微环境(核孔)。球粒陨石和植藻之间的这种密切关系支持了植藻生产者的序列行为假说。所研究的地区还产微藻(Helminthopsis tenuis)， Planolites

期刊介绍： Acta Palaeontologica Polonica is an international quarterly journal publishing papers of general interest from all areas of paleontology. Since its founding by Roman Kozłowski in 1956, various currents of modern paleontology have been represented in the contents of the journal, especially those rooted in biologically oriented paleontology, an area he helped establish. In-depth studies of all kinds of fossils, of the mode of life of ancient organisms and structure of their skeletons are welcome, as those offering stratigraphically ordered evidence of evolution. Work on vertebrates and applications of fossil evidence to developmental studies, both ontogeny and astogeny of clonal organisms, have a long tradition in our journal. Evolution of the biosphere and its ecosystems, as inferred from geochemical evidence, has also been the focus of studies published in the journal.
