Abstract

The fossil record indicates that complex multicellular organisms started to become dominant in the second half of the Neoproterozoic. However, many macroscopic fossils of this period are not yet well understood. As one example, the Jinxian Biota includes some affinity-unresolved, millimeter- to centimeter-sized discoid fossils of probable pre-Ediacaran age from the shales of the Xingmincun Formation, in southern Liaodong Peninsula, China. This paper presents new observations of these fossils based on new material. Three types of preservation were identified and analyzed. The organisms were probably transported by turbidity currents, rapidly buried in fine-grained deposits and then compacted to yield thin films. Pyrite- and carbonate-related mineralization may have been involved in their early diagenesis, but local-controlled late diagenesis altered the fossil-related mineral composition to that observed today. The concentric annular relief on the fossil surfaces exhibits a “half convex, half concave” pattern, which is interpreted to reflect the differentiated mechanical nature between adjacent annuli. New specimens have been found that support the existence of programmed fission and budding. In addition, another group of previously ignored discoid fossils are first described here. With the same preservation as the “normal” discs, these fossils lack any concentric relief and always occur in clusters. The relationship between the two types of discs remains unclear. Even with all of the new information, it remains impossible to indubitably correlate the Jinxian Biota to any known taxonomic group. However, it is quite probable that these fossils represent a group of eukaryotic organisms.

Kurzfassung

Der fossile Bericht zeigt, dass größere komplexe Organismen erst in der zweiten Hälfte des Neoproterozoikums (Cryogenium) erscheinen. Allerdings sind diese Fossilien nur schwer interpretierbar und es ist nicht möglich sie heutigen Metazoen zu zuordnen. Ein Beispiel dafür sind die bis einige Zentimeter großen scheibenförmigen Fossilien aus der Xingmincun Formation (südliche Liaodong Halbinsel, Nordchina). In der vorliegenden Arbeit werden neue Beobachtungen zur Paläobiologie dieser Fossilien beschrieben basierend auf drei unterschiedlichen Erhaltungsstadien. Die Organismen wurden sehr wahrscheinlich in Suspensionswolken von feinkörnigen Mikroturbiditen transportiert und durch diesen Prozess rasch im Sediment eingebettet. Durch diesen Vorgang wurden sie zu dünnen Scheiben kompaktiert. Es lassen sich drei unterschiedliche Erhaltungstypen, bedingt durch unterschiedliche diagenetische Bedingungen, unterscheiden. Die drei verschiedenen Diagenestypen unterscheiden sich in den assoziierten Mineralien und in der Dicke der Scheiben. Die Scheiben zeigen konzentrische, reliefartige Muster mit halb konvexen und halb konkaven Kompaktionsstrukturen. Neben diesen spezifischen Oberflächenstrukturen finden sich Teilungs- und Knospungsmuster. Es wird eine weitere Form dieser Scheiben-Fossilien beschrieben, die keine konzentrischen Strukturen aufweisen und stets zusammen mit vielen Individuen auftreten (Schwarm). Die vorgestellten Fossilien zeigen gute Übereinstimmungen mit den “Beltanelliformis” Fossilien der unterkambrischen Pusa Formation in Spanien. Eine engere taxonomische Zuordnung zu einem bekannten Taxon konnte bis dato nicht vorgenommen werden.
