Dortokidae is an extinct family of freshwater pan-pleurodiran turtles, known from the Cretaceous and Paleocene of Europe. Only four species have been named, but indeterminate fossils show that they were abundant across western and eastern-central Europe during the Cretaceous. The family is only known from postcranial remains.[1]

Genera

  • Eodortoka Pérez-García, Gasulla, and Ortega 2014[2] Wessex Formation, United Kingdom Early Cretaceous (Hauterivian-Barremian)[3] Arcillas de Morella Formation, Spain, Early Cretaceous (Aptian)
  • Dortoka Lapparent de Broin and Murelaga, 1999 Laño site, Spain, (probably also present in southern France) Late Cretaceous (Campanian-Maastrichtian) Sînpetru Formation, Romania, Late Cretaceous (Maastrichtian)
  • Ronella Lapparent de Broin in Gheerbrant et al. 1999 Jibou Formation, Romania Paleocene (Thanetian) (alternatively considered a species of Dortoka)

An indeterminate dortokid is also known from the Hauterivian-Barremian aged El Castellar Formation in Spain.[1]
