That disagrees with what my biology books in school said, but appears both
more recent and authoritative. Anyways, I noted just after the bit you
quoted that the group containing mammals, lizzards, dinos etc might be
called something else. My point still stands, whether you look at what Tree
of Life calls Amniota or Reptilia.
