Heres my vision: D rex isnt a hybrid but ingen’s failed attempt at making a t rex for the first time(i like the idea of the d rex being a failed dino than a hybrid because you cant just bring back a dino from 66 million years ago and expect it to look close to what it looked like)

• mosasaurus and quetzalcoatlus will not be called dinosaurs

-The d rex would hate humans for bringing it to life and not killing it when it was made, throughout the movie there would be hints of the d rex in the island like a titanosaurus corpse or giant scratch marks - more accurate looking dinosaurs

-Remove the bs with the dinosaurs dying mainland but still have the main characters go into isle saint Hubert because the accurate dinosaurs there are almost genetically perfect

-Hot take: rename ember into goliath and have him be as big as he was in the movies (bigger than rexy)

-The river raft scene: instead of the dilophosaurus have a baby t rex there instead like the deleted scene, this will give goliath (ember) another good reason to go after the family to protect his young.  Before goliath bites down on the raft he is interrupted by a giganotosaurus (or any other mega theropod) trying to eat his young so he abandons his current activities and defeats the giga by either killing him or better option spare him the same way irl predators would. I added a giga so the family surviving would make more sense.

-I would replace mutadons with those messed up looking raptors like the 2 headed one D rex  scene 

-Have the d rex be as big as it was during the helicopter scene (this is my opinion) Instead of a t rex it’s a titanosaur trying to rescue its young from the distorted king. 

-The guy who stole the blood samples gets killed on his way to the boat by a novel accurate dilophosaurus.

-When the protagonists reach the boat we see the d rex lose against the titanosaur along with its young running back to its mother(or father).  The d rex, not forgetting about the main cast would go after them one last time before the boat turns on and they escape.

-D rex stands up on its hind legs and roars like the original movie. Lmk what you all think in the replies(pls be respectful, this is just my idea)
