_Sauropsida_ *is* used for the stem group, and _Reptilia_ for the crown
clade. I've never heard of _Eureptilia_ before ... I thought I made it up!

Oh yeah ... I wonder where I got those from ... I think "Ostei" would be
a much better name, but if these have priority....

Although, as you mentioned, there is the alternative Theropsida for
_Synapsida_, and there's also Neotheropsida (I think Bakker named it) for
_Therapsida_. Tough call....
