Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 21, Iss 2, Pp n/a-n/a (2020)

Abstract International Ocean Discovery Program Expeditions 352 and 351 drilled into the Western Pacific Izu‐Bonin forearc and rear arc. The drill cores revealed that the forearc is composed of forearc basalts (FAB) and boninites and the rear arc co

Experimental mineralization of crustacean eggs: new implications for the fossilization of Precambrian–Cambrian embryos

Autor: D. Hippler, N. Hu, M. Steiner, G. Scholtz, G. Franz

Publikováno v: Biogeosciences, Vol 9, Iss 5, Pp 1765-1775 (2012)

Phosphatized globular microfossils from the Ediacaran and lower Cambrian of South China represent an impressive record of early animal evolution and development. However, their phylogenetic affinity is strongly debated. Understanding key processes an

Publikováno v: Biogeosciences, Vol 6, Iss 1, Pp 1-14 (2009)

The accurate reconstruction of sea surface temperature (SST) history in climate-sensitive regions (e.g. tropical and polar oceans) became a challenging task in palaeoceanographic research. Biogenic shell carbonate SST proxies successfully developed f

THE LATE CRETACEOUS VERTEBRATE ICHNOFACIES OF BOLIVIA - FACTS AND IMPLICATIONS

Autor: C. A. Meyer, D. Hippler, M. G. Lockley

Publikováno v: Publicación Electrónica de la Asociación Paleontológica Argentina, Vol 7, Iss 1 (2015)

Cretaceous dinosaur tracks are known in Central Bolivia since 1968. Recent work shows that tracksites are widespread and occur in multiple layers from the Campanian to the Late Maastrichtian. The ichnofauna is associated with alluvial to deltaic as w
