These all stem from Dale Russell's 1970 hypothetical long-legged juvenile
tyrannosaurid reconstruction. The really young Tarbosaurus or Jenghizkhan
juvenile (probably Tarbosaurus, because it has a very wide frontal notch in
the upper rim of the orbit) has never been described, and I've seen only one
photo of it, in a Japanese exhibition guidebook. More input is desperately

Maleevosaurus was considered a half-grown Tarbosaurus by Rozhdestvensky
(before it was separated out as Maleevosaurus), but Ken Carpenter showed that
this was unlikely.
