This is one of my (admittedly many) pet peeves. Does anyone speak
about the mammal-bat transition? The primate-human transition? The
animal-vertebrate transition? No, because bats *are* mammals, humans
*are* primates, and vertebrates *are* animals.
There is no "theropod-bird transition" because birds are *still*
theropods. Nor is there a "theropod-abelisaurid transition" or a
"theropod-tyrannosauroid transition" or a "theropod-sphenisciform
The term is a holdover from typological thinking, where the archetypal
theropod becomes the archetypal bird (through the archetypal "missing
[not really] link [maybe]", _Archaeopteryx_).
I know what is meant, but I think it's better termed "the bird stem lineage".
