Re: Shedding archosaurs?
Could members of archosauria have been both skin-shedders *and* endothermic?
Only lepidosaurs, or only squamates (I don't know), shed large parts
of their epidermis at once,
The pattern for shedding in lepidosaurs is complex and apparently
associated with their unique epidermal growth pattern. In tuataras,
and the majority of lizards, skin sheds in big patches while in
snakes the skin normally sloughs in a single piece, but in all
lpidosaurs, the sequence of epidermal growth and shedding is
basically the same.
