The past decade has seen an exponential increase of innovative applications of 3D technology in the geosciences. Here, we present a case study from the Florida Museum of Natural History applied to the multidisciplinary field of paleontology. We have deployed 3D scanning and printing techniques for the purposes of scientific research, formal education, and informal outreach. Depending on the application of the 3D file, different techniques are utilized to create high-fidelity models of physical fossil specimens or geologic field sites. These techniques include X-ray CT scans, surface scans, and photogrammetry, all of which produce 3D models that vary in resolution and scale. Novel paleontological research applied non-destructive CT scanning to explore the internal anatomy of fossil museum specimens, additionally, 3D models are being used to create K–12 curricula aligned with national and state-specific education standards that are implemented in formal classroom settings. Many of these lessons are part of the NSF-funded iDigFossils project, which aims to evaluate students’ motivation and interest towards science, technology, engineering, and mathematics after participating in integrated 3D printing and paleontology lessons. Specifically, lessons on dinosaur trackways, horse evolution, and the Great American Biotic Interchange teach geologic concepts such as deep time, taphonomy, plate tectonics, and evolutionary trends. The same 3D models developed for these K–12 lessons have been used during Florida Museum’s outreach events to engage broad audiences with hands-on exhibits and activities. All 3D files are stored on open-access, online repositories, providing accessibility to fossil specimens and field sites. The application of 3D technology for the study of fossils and paleontology will continue to expand the impact of scientific discoveries for basic research as well as for broader impacts on society.

Abstract This contribution presents a general account and summary of the research carried out over the past decades on the Quaternary faunas of France. This country is located in the center of Western Europe, and presents distinct topographical features and very varied climatic influences. This paper is the result of collaborative work between French teams and different researchers specialized in the paleontology of large mammals. Over a hundred paleontological or archaeological sites are mentioned in this review, which covers a broad chronological period, ranging from the Early (including the end of Pliocene/Gelasien) and Middle Pleistocene to the Late Pleistocene. One of the aims of this work is to present studies of the main families or subfamilies of herbivores (Equidae, Rhinocerotidae, Bovidae [Bovines, Caprines, Antilopines, and Rupicaprines], Cervidae, Proboscid) and carnivores (Canidae, Ursidae, Mustelidae, Hyenidae, Felidae). It is not exhaustive at the generic and specific level, but details on the taxonomic status, evolutionary levels and biochronological importance of the most important taxa are given alongside an extensive and up-to-date bibliography of French works.

ABSTRACT This paper is the first integrated account of the sedimentology, stratigraphy, and vertebrate paleontology for the marine strata of the Chilcatay Formation exposed at Ullujaya, Pisco basin (southern Peru). An allostratigraphic framework for the investigated strata was established using geological mapping (1:4000 scale) and conventional sedimentary facies analysis and resulted in recognition of two unconformity-bounded allomembers (designated Ct1 and Ct2 in ascending order). The chronostratigraphic framework is well constrained by integration of micropaleontological data and isotope geochronology and indicates deposition during the early Miocene. The marine vertebrate fossil assemblage is largely dominated by cetaceans (odontocetes), whereas isolated teeth and spines indicate a well-diversified elasmobranch assemblage. Our field surveys, conducted to evaluate the paleontological sensitivity of the investigated strata, indicate that vertebrate remains only came from a rather restricted stratigraphic interval of the Ct1 allomember and reveal the high potential for these sediments to yield abundant and scientifically significant fossil assemblages.

The paleogeographic reconstruction of the Brazilian sedimentary basins during the Albian-Aptian interval has been a controversial issue for over a decade. The tectonic dynamics, as well as the stratigraphy, sedimentology and paleontology of those basins are closely related to the origin and evolution of the South Atlantic Ocean.
