Caddisfly larvae construct underwater protective cases using surrounding materials, thus providing information on environmental conditions in both modern and ancient systems. Microbial bioherms associated with caddisfly cases are found in the Berriassian-Hauterivian (~140-130 Ma) Shinekhudag Formation of Mongolia, and yield new insights into aspects of lacustrine paleoecosystems and paleoenviro...

Plate reconstructions of the Panthalassa Ocean typically portray a simple system diverging plates surrounded by active margins, yet geological and seismic tomographic records demonstrate that intra-oceanic subduction existed. Here, we reconstruct plate tectonic evolution pre-Cretaceous Oku-Niikappu island arc, remnants which are exposed on Hokkaido, Japan. This arc formed at Jurassic zone separ...

Taphonomy and mineralization of carbonated wood from the Purbeckian facies l'Usine, Cherves-Richemont (Charente). Lower Cretaceous deposits Charentes region, in southwestern France, correspond to continental brackish environments, locally rich evaporitic formations (Manès 1850; Pouech et al. 2006, 2014, 2015; Schnyder 2012; Vullo 2014; Moreau 2017b). Three fossiliferous localities have been pre...

Paléobiodiversité des vertébrés du Lagerstätte Crétacé inférieur (Berriasien) d'Angeac-Charente (sud-ouest de la France), implications pour le renouvellement faunique continental à limite J/K. La faune continentaux, représentée fois par macro- et microrestes, Berriasien est décrite ici. Cette riche diversifiée comprend au moins 38 taxons différents provenant tous les grands clades constituée pl...
