Abstract in brief

  • Diictodon, an ancient Permian herbivorous dicynodont, is notable for being the earliest known example of sexual dimorphism in armaments, mainly through the presence or absence of tusks.
  • The study of Diictodon's anatomy and distribution shows that tusk presence is linked to other features like cranial bosses and possibly larger skull size, indicating differences between sexes.
  • This evidence suggests that sexual dimorphism and related social behaviors have been a part of synapsid evolution for a very long time, dating back to the Palaeozoic era.

@TwitiGalli Also relevant are possibly sexually dimorphic and/or display features on the heads. In life such features might have been colourful and exaggerated. A review of sexual dimorphism in dicynodonts is in: https://t.co/b2qnYURDr5 Sexual dimorphism in diictodon: https://t.co/aeAQputXHJ
