The last surviving Thalassochelydia — A new turtle cranium from the Early Cretaceous of the Purbeck Group (Dorset, UK)

Anquetin, Jérémy ; André, Charlotte

In: PaleorXiv, 2020, p. 7pa5c

Background. The mostly Berriasian (Early Cretaceous) Purbeck Group of southern England has produced a rich turtle fauna dominated by the freshwater paracryptodires Pleurosternon bullockii and Dorsetochelys typocardium. Each of these species is known by numerous relatively complete shells and by a single cranium. The two other turtles found in the Purbeck Group (Hylaeochelys belli, a species of...

InvasiBES: Understanding and managing the impacts of Invasive alien species on Biodiversity and Ecosystem Services

Gallardo, Belinda ; Bacher, Sven ; Bradley, Bethany ; Comín, Francisco A. ; Gallien, Laure ; Jeschke, Jonathan M. ; Sorte, Cascade J. B. ; Vilà, Montserrat

In: NeoBiota, 2019, vol. 50, p. 109–122

Invasive Alien Species (IAS) are amongst the most significant drivers of species extinction and ecosystem degradation, causing negative impacts on ecosystem services and human well-being. InvasiBES, a project funded by BiodivERsA-Belmont Forum for 2019–2021, will use data and models across scales, habitats and species to understand and anticipate the multi-faceted impacts of IAS and to...

The Cretaceous of the Swiss Jura Mountains: an improved lithostratigraphic scheme

Strasser, André ; Charollais, Jean ; Conrad, Marc André ; Clavel, Bernard ; Pictet, Antoine ; Mastrangelo, Bruno

In: Swiss Journal of Geosciences, 2016, vol. 109, no. 2, p. 201–220

In the course of the HARMOS project of the Swiss Geological Survey, the lithostratigraphic subdivisions of the Cretaceous sedimentary rocks outcropping in the Swiss Jura Mountains were revisited. New formation names are proposed where only inadequate facies terms existed so far. As in some cases outcrop conditions in the Swiss Jura do not allow for logging complete sections to characterise...

Plate tectonics drive tropical reef biodiversity dynamics

Leprieur, Fabien ; Descombes, Patrice ; Gaboriau, Théo ; Cowman, Peter F. ; Parravicini, Valeriano ; Kulbicki, Michel ; Melián, Carlos J. ; Santana, Charles N. de ; Heine, Christian ; Mouillot, David ; Bellwood, David R. ; Pellissier, Loïc

In: Nature Communications, 2016, vol. 7, p. 11461

The Cretaceous breakup of Gondwana strongly modified the global distribution of shallow tropical seas reshaping the geographic configuration of marine basins. However, the links between tropical reef availability, plate tectonic processes and marine biodiversity distribution patterns are still unknown. Here, we show that a spatial diversification model constrained by absolute plate motions...

Guelb el Ahmar (Bathonian, Anoual Syncline, eastern Morocco): First continental flora and fauna including mammals from the Middle Jurassic of Africa

Haddoumi, Hamid ; Allain, Ronan ; Meslouh, Said ; Metais, Grégoire ; Monbaron, Michel ; Pons, Denise ; Rage, Jean-Claude ; Vullo, Romain ; Zouhri, Samir ; Gheerbrant, Emmanuel

In: Gondwana Research, 2016, vol. 29, no. 1, p. 290–319

We report the discovery in Mesozoic continental “red beds” of Anoual Syncline, Morocco, of the new Guelb el Ahmar (GEA) fossiliferous sites in the Bathonian Anoual Formation. They produced one of the richest continental biotic assemblages from the Jurassic of Gondwana, including plants, invertebrates and vertebrates. Both the sedimentological facies and the biotic assemblage indicate a...
