That's where I disagree. All one is doing is taking
the same problem and giving it a new paint job.
Even if the name could be removed, there would be
decades of inertia to deal with (if not more). There
would be constant mentions of "group X, formerly
reptiles", or "groups XYZ (used to be called
It would be as bad as the bloody awful "non-avian

Just the usual. I'm not a fan of ever inclusive names
As Ken Carpenter had so aptly put it; when one uses
this 'nesting doll' classification system, it:
"makes us hairy fishes!"
For some folks that's fine. Personally I think it just
confuses matters more.

You're acting like it's being ignored currently. The
relationship between crocs and birds has been
acknowledged for at least 30 years. It still has done
little to eliminate the misconceptions about them.
Hell, Bakker made mention of how crocodiles are "more
bird than reptile," yet it didn't stop him from
treating crocs like "typical reptiles" in Heresies
(all the more ironic given that he chastised the "old
guard" for doing that very same thing).

I guess we'll have to agree to disagree there.
