Shifts in the Ediacaran to Lower Ordovician sedimentary zircon provenances of Northwest Gondwana: the Pyrenean files
Autor: Maxime Padel, Sébastien Clausen, Marc Poujol, J. Javier Álvaro
Publikováno v: Geologica Acta, Vol 20, Iss 14, Pp 1-18 (2022)
Detrital zircon grains from Cambrian–Lower Ordovician sandstones and quartzites sampled in the Pyrenees were dated by LA-ICPMS in order to assess their provenance sources. Resulting age distributions are compared to other available datasets from ne

A stem group echinoderm from the basal Cambrian of China and the origins of Ambulacraria
Autor: Timothy P. Topper, Junfeng Guo, Sébastien Clausen, Christian B. Skovsted, Zhifei Zhang
Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-8 (2019)
The early evolution of the deuterostomes is not well resolved. Here, Topper and colleagues investigate the early Cambrian metazoan Yanjiahella biscarpa, concluding that it is a stem echinoderm, is among the oldest known deuterstomes, and supports an

Terreneuvian orthothecid (Hyolitha) digestive tracts from northern Montagne Noire, France; taphonomic, ontogenetic and phylogenetic implications.
Autor: Léa Devaere, Sébastien Clausen, J Javier Alvaro, John S Peel, Daniel Vachard
Publikováno v: PLoS ONE, Vol 9, Iss 2, p e88583 (2014)
More than 285 specimens of Conotheca subcurvata with three-dimensionally preserved digestive tracts were recovered from the Terreneuvian (early Cambrian) Heraultia Limestone of the northern Montagne Noire, southern France. They represent one of the o

The Cambrian stratigraphic succession of the Pyrenees (SW Europe) has undergone a complex Variscan and Alpine tectonothermal history leading to marked metamorphism and development of cleavage networks, which might partly explain the lack of Cambrian

From the wake of the Marinoan glaciations to the early Cambrian, the global ocean experienced progressive but likely nonuniform and nonlinear oxygenation to levels that, although still low with respect to the modern ocean, and might be therefrom trig
