Research on Fossil Material from China

1. 2005 ––: Collaboration on 'Orsten'-type fossils --- 2. 2001–2004: D.F.G. Bundle Project

1. Collaboration on 'Orsten'-type fossils with Proffs. Dong and Zhang

Projects started in 2005. The collaboration with Professor Zhang from Kunming, China, is on crustaceans in an 'Orsten' type of preservation. So far it has led to one publication in NATURE and now, June 22, 2010, to another nice paper in CURRENT BIOLOGY.

A joint paper of Andreas Maas with Prof. Dong is in press. This paper is on similarly 3D preserved phosphatocopines.

2. 2001 – 04/2005: D.F.G.-Project „Biological, Preservational and Evolutionary Aspects of Macro- and Meiofaunal Biota of the Yangtze Platform at the Precambrian-Cambrian Transition“

  • This project of Dieter Waloszek and Andreas Maas together with Andreas Braun, Bonn, and Martin Stein (until 3/04), now Kansas, USA, from summer 2001 to April 2005 was part of a so-called bundle programme jointly funded by the Deutschen Forschungsgemeinschaft D.F.G. and the Chinese National Science Foundation NSFC named "The Cambrian Bio-Radiation Event: A multidisciplinary Approach to Bio-Earth-System Evolution, geophysiology of the Yangtze Platform, P.R. China" (German co-ordinators: Prof. Dr. B. Erdtmann & Dr. M. Steiner, Berlin). The programm was a joint venture of several institutions in Germany (u. a. Freie und Technische Universität Berlin, Bonn, Clausthal-Zellerfeld – Lehmann, Münster – Harald Strauss, and Ulm) and a similar number of chinese partner institutions.

  • In this multi-disciplinary approach we have studied aspects of the early geological and biological development of the largest continental plate of China.

  • Research topics of the whole programme: Problems of late Proterozoic glaciations, sea geochemistry, sedimentations, stratigraphy, palaeo-ecology and palaeobiology of the early Cambrian (microfaunas, plankton, macrofaunas).

    Our specific topic was on Lower Cambrian Maotianshan-Shale Micro- and Macrofossils. Besides the description of two important new species, one belonging to the stem lineage or modern chelicerates and one being an early offshoot what we call the Arthropoda s. str., all those arthropods, which are clearly sclerotized, we also discussed more general aspects of life habits and the evolution of feeding. And we also investigated nemathelminth fossils, which play an important r

    le in the benthic community of the Chengjiang faunas.

    Andreas Braun was particularly working on the micro fossils, e.g. radiolarians.
