My reasonings
The locations are the same (rocky, sandy beach with forestry cliffs and hills).
Has the same wildlife including Tyrannosaurus, Mosasaur and Archelon.
Same period being Late Cretaceous
There were also Cretoxyrhina, Xiphactinus and Pteranodon, which iirc were all dead by the Maastrichtian. Plus the mosasaurs in Sea Monsters were Tylosaurus. Archelon was kinda dead by then too, it was legit just a giant protostegid.
But about the T.Rex...
CAN IT TIME TRAVEL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
What do you think?
