[dinosaur] When did T. rex evolve?



Good day,

I would like to ask, what is the most exact geologic age setting for _Tyrannosaurus rex_? Lower limit would be 66.0 mya of course, but what about its earliest fossil remains? One study gave age of some 67.4 mya, but is that generally agreed upon? Thank you in advance, Tom
