That's not entirely what I said:

"Carpenter (1990) argued that the Texas specimen (TMM 41436-1, an isolated left 
maxilla) lies outside the range of shape variation for T. rex, but the 
morphology of the promaxillary foramen and the number of teeth are both 
consistent with T. rex (pers. obs.).  If it is a different species, it is a 
close relative."

In other words, it's either T. rex OR a close relative.
