Si les collections minéralogiques rassemblées par Séguier n’ont rien d’exceptionnel, ni d’a priori singulières, elles n’en tinrent pas moins un rôle important dans sa carrière savante, reflétant les inflexions de ses centres d’intérêt. D’abord au service de l’étude des fossiles, en tant qu’outil de référence, elles alimentèrent ultérieurement ses r...
The natural environment of the Gansu-Qinghai region in northwest China exhibits spatial variation, resulting in distinct adaptive strategies among populations in different geographical areas. In this study, we analyzed the diachronic trend and regional variations in caries prevalence among 10 different middle and late-Holocene groups by examining d...
Based on sediment traps moored in the southern Ionian Sea (Eastern Mediterranean), this paper documents nassellarian radiolarian occurrences (54 species). Several taxa are reported and illustrated for the first time for the Mediterranean Sea (i.e., Trisulcus triacanthus, Tricerapyris damaecornis, Archiperidium longispinum and Artostrobus joergensen...
Characterizing the processes underlying reproductive isolation between diverging lineages is central to understanding speciation. Here, we present RIDGE-Reproductive Isolation Detection using Genomic polymorphisms-a tool tailored for quantifying gene flow barrier proportion and identifying the relevant genomic regions. RIDGE relies on an Approximat...
The Metasuchia appeared during the Jurassic. At the Cretaceous, its diversity included semi-aquatic (e.g. Eusuchia) as well as marine (Tethysuchia) and terrestrial (Notosuchia) organisms. During its evolutionary history, it crossed two major crisis event, the OAE2 and the K/Pg boundary. The response of the Metasuchia to each was different as the fi...
peer reviewed / [en] UNLABELLED: The aim of this study is to evaluate the effect on the initiation of new blood vessel formation of rh-BMP-2 administration in the human gingival tissue during bone regeneration surgery. MATERIAL AND METHODS: The randomized controlled clinical trial included twenty patients with bilateral partial edentulous of the ma...
Nearctic ungulates such as artiodactyls, perissodactyls, and proboscideans arrived in South America during the Great American Biotic Interchange. Among them are camelids, cervids, tayassuids, equids, tapirids and gomphotherids. A historical collection of Nearctic ungulates from Pleistocene deposits of the Pampean region in Argentina is here studied...
Fossils of Cretaceous sea turtles adapted to an open marine lifestyle remain rare finds to date. Furthermore, the relationships between extant sea turtles, chelonioids, and other Mesozoic marine turtles are still contested, with one key species being Santanachelysgaffneyi Hirayama, 1998, long considered the earliest true sea turtle. The species is ...
The “human fossil” from Baradero, Buenos Aires Province, Argentina, is a collection of skeleton parts first recovered by the paleontologist Santiago Roth and further studied by the anthropologist Rudolf Martin. By the end of the nineteenth century and beginning of the twentieth century it was considered one of the oldest human skeletons from South ...
