JW is going to take place 22 years after than Jurassic Park's events. Now, Rexy firstly appeared in Jurassic Park, right? So 22 years ago.
But of course Rexy wasn't a baby. By 1993, she was already fully grown.
JW will take place 22 years after than Jurassic Park, yet Rexy is going to return. That's bordeline impossible, given that Rexy was already fully grown on 1993. Bear in mind that Tyrannosaurus usually stopped growing at around 20.
Based on Erickson et. al (2004)
So we can assume that Rexy was already 20 by 1993...if she's going to appear in JW, she would be 42 years old.
She would be very very very old, given that "Sue", the largest know Tyrannosaurus specimen, was 28 when it died. Ericknos et. al stated that "Sue"'s age should be close to the maximum for Tyrannosaurus. So, Rexy should be theorically died or at least very very very old. Yet, in her artwork, she doesn't like old.
Thus, I think that using Rexy in this film is somehwhat of strange.
