I think this is deducing way too far! The T. rex reference is in a
relatively artistic sentence ("...better display of Northern & Southern
Lights...") rather than in any direct quotation by the researchers. I
strongly suspect that the name "T. rex" was used because it is the best
known Cretaceous dinosaur: unfortunately, it is a LATEST Cretaceous
Not a single other phrase concerning the data or quotes from the researchers
implies suggestions on their part that the high intensity extended into C33
or later. (Incidentally, T. rex lived in C30n and died during C29r).
So I think that the use of the name T. rex was (inaccurate) artistic

No, it does not. I'm glad they didn't use a Jurassic dinosaur!
