Ceratosaurians also had strongly curved S-shaped necks like birds do; this is a trait inherited from a distant archosaurian ancestor.
It is interesting that as the archosaurian reptiles were becoming larger, the cynodonts became smaller, perhaps nocturnal.
The hot dry Pangean deserts of the Triassic would witness the competition between the synapsid proto-mammals that had dominated the land uptil now, and the newly emerged archosaurian reptiles (thecodonts).
However, as Bock recently cautioned, ‘it is best to consider birds as part of the great archosaurian radiation without being more specific, as has been agreed by zoologists for more than a century.’
The first vertebrates to evolve true flight were the pterosaurs, flying archosaurian reptiles.
