heres some gumph from the ICZN (someone will correct me if wrong !);

i guess that there is a clause that says that if a name has been in
common usage (and there is time limit for this, I forget) but that
subsequently turns out to be preoccupied (like T rex in this case), then
the younger (more used) one can be made a nomen protectum ?.

the older name gets designated a nomen oblitum ?

---- a similar thing could have to happen with the fossil duck
Presbyornis.
