• Systematic : Coelenterata: Scleractinia/Octocorallia
• Stratigraphic : Triassic-Cenozoic
  • Families, Genera : all
  • Species : fossil (Triassic-Coenozoic)
  • Citations:
    • Triassic : in process
    • Jurassic : almost complete - 95% of the citations of Jurassic corals were obtained from a text file built up by Bernard Lathuilière (Nancy) for which I am very grateful
    • Cretaceous : complete and up to date
    • Cenozoic : in process
• Geographic : Worldwide

Reason

• Information system and creation of a systematic catalogue (only Cretaceous)
• Systematic revision of the Cretaceous corals on the genus level
• Estimation on palaeobiogeography, diversity, evolution ...
• Morphometric data, numeric taxonomy, PCA

  • Jurassic : 2900
  • Cretaceous : 3070
