Subject: Re: Kinetic skulls
I'd like to know the first theropod showing skull
kinesis homologous to that found in birds.
Not really much of an answer to your question,
but the basal pygostylian Confuciusornis lacks a kinetic skull, perhaps
suggesting any development in non-avian theropods (like mononykines) was in
parallel to ornithothoracine birds.
