Overview

Daniel Vachard is affiliated with the University of Lille in France and specializes in Earth and Planetary Sciences, with a significant focus on paleontology. Their research portfolio includes over 80 publications in this domain, with notable contributions to subfields such as Paleontology, Atmospheric Science, Geophysics, Earth-Surface Processes, and Geology.

The scientist's research themes encompass a broad range of topics within Earth sciences. Key areas of work include Paleontology and Stratigraphy of Fossils, Geology and Paleoclimatology Research, Geological and Geochemical Analysis, Geological formations and processes, Geological and Geophysical Studies Worldwide, Evolution and Paleontology Studies, and Geological and Geophysical Studies.

Recent publications demonstrate an emphasis on both paleobiogeographic and stratigraphic studies, primarily related to the Carboniferous period and analogous geologic contexts. Some recent papers include:

  • Lower-middle Viséan transgressive carbonates in Morocco: Palaeobiogeographic insights (2020, Journal of African Earth Sciences)
  • Refined foraminiferal biostratigraphy of upper Wordian, Capitanian, and Wuchiapingian strata in Hambast Valley, Abadeh region (Iran), and paleobiogeographic implications (2020, Geological Journal)
  • Carboniferous smaller Foraminifera: convergences and divergences (2020, Geological Society London Special Publications)
  • The Pennsylvanian System in the Sacramento Mountains, New Mexico, USA (2021, Smithsonian contributions to paleobiology)
  • Contrasting reef patterns during the evolution of the carboniferous azrou-khenifra basin (Moroccan Meseta) (2022, Facies)

Frequent collaboration is a feature of this scientist's work. Regular co-authors include Ismael Coronado, Pedro Cózar, Alain Izart, Ian D. Somerville, and Spencer G. Lucas.

The venues where publications appear most frequently include Facies, Journal of Asian Earth Sciences, Geobios, Carnets de géologie (Notebooks on geology), and Journal of African Earth Sciences. These journals reflect the scientist's focus on integrating paleontological data with geological and stratigraphic frameworks across various geographic regions.
