Kranosaura is an extinct genus of archosauriform reptile from the Late Triassic Upper Maleri Formation of India. It contains a single species, K. kuttyi.
Discovery and naming
[edit]The genus is based on two domes of 9 centimetres (3.5 in) long, discovered by T. S. Kutty in the 1990s and described in 2021 by Nesbitt et al.[1]
Description
[edit]It had an unusually domed head reminiscent of the later pachycephalosaurian dinosaurs in an example of convergent evolution, similar to that of Triopticus.[2] Kranosaura was the sister taxon to Triopticus, with which it forms the clade Protopyknosia.[1]
