摘要

在非洲首次报道了丰富的planus caroichnus SMITH & CRIMES, 1983。它们产于阿尔及利亚西北部Tiaret附近中新世下的深海矿床。该痕迹的形态特征，加上该地区记录的Cardioichnus与棘球纲之间的空间相互关系，提供了证据，表明地方性的棘球纲Echinocardium nummuliticum PÉRON & GAUTHIER, 1885代表了所研究的C. planus的痕迹。Cardioichnus为上侏罗统至更新世所知，具有广泛的地理和环境分布。

The trace fossil Cardioichnus planus from the lower Miocene of Algeria: the first record from Africa and a probable endemic tracemaker

Abundant Cardioichnus planus SMITH & CRIMES, 1983 have been reported for the first time from Africa. They occur in lower Miocene deep-marine deposits near Tiaret in northwestern Algeria. Morphological features of the trace, coupled with the spatial interrelationships between Cardioichnus and the echinoids documented in this area, provide evidence that the endemic spatangoid Echinocardium nummuliticum PÉRON & GAUTHIER, 1885 represents the tracemaker of the studied C. planus. Cardioichnus is known from the upper Jurassic to the Pleistocene and it has a wide geographic and environmental distribution.

期刊介绍： Geologia Croatica welcomes original scientific papers dealing with diverse aspects of geology and geological engineering, the history of the Earth, and the physical changes that the Earth has undergone or it is undergoing. The Journal covers a wide spectrum of geology disciplines (palaeontology, stratigraphy, mineralogy, sedimentology, petrology, geochemistry, structural geology, karstology, hydrogeology and engineering geology) including pedogenesis, petroleum geology and environmental geology. Papers especially concerning the Pannonian Basin, Dinarides, the Adriatic/Mediterranean region, as well as notes and reviews interesting to a wider audience (e.g. review papers, book reviews, and notes) are welcome.
