Other mistake: In Jurassic World, we are told that the Gyrosphere can stop a .50 calibre bullet. When it falls into the sea in this film, Owen shoots some holes in it using a pistol and manages to prise the door off using a small knife.
Other mistake: When the Indoraptor bites off Wheatley's arm, there is absolutely no blood coming from such a massive wound. The remnants of his torn shirt are completely dry.
