New bone-headed archosauriform from India

Recommended Posts

A new paper is out online:


Nesbitt, S. J.; Stocker, M. R.; Chatterjee, S.; Horner, J. R., & Goodwin, M. B., 2021. A remarkable group of thick‐headed Triassic Period archosauromorphs with a wide, possibly Pangean distribution. Journal of Anatomy In press. doi:10.1111/joa.13414.


I remember the "Triassic pachycephalosaur" from India that was discussed at a number of vertebrate paleontology symposia by Sankar Chatterjee, but the description of this form as Kranosaura reinforces my opinion about the "Triassic pachycephalosaur" being a Triopticus relative. The paper also erects the clade Protopyknosia to include both Kranosaura and Triopticus.
