Continuity mistake: In the fossil room, Owen, Claire and Maisie take off running from the Indoraptor and it leaps off some bones after them. It lands only about a couple feet away from Owen and starts to slide, but in the next shot when it cuts to a different angle, suddenly Owen and the others are several yards away from it at the stairs already. (01:38:15)
Continuity mistake: Franklin plugs in a computer and then snaps his fingers pointing to the left and says "hand" for Claire. It cuts to a different angle as Claire starts to walk where he pointed and suddenly Franklin's arm is back down between shots. (00:29:45)
Audio problem: When Maisie is complaining to Iris that she doesn't want a bath, Iris says "What?" while visible on the left of screen with her head askew to the camera. However her mouth movement doesn't match the audio as you hear her say "What?" her mouth doesn't move till after you hear her say it. (00:23:00)
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.

Continuity mistake: On Isla Nublar when Claire is running her shirt can be seen without any shoulder sleeves, but for the rest of the film she suddenly has shoulder sleeves.
Continuity mistake: At the start of the bar scene, Claire is laughing hysterically and it shows a shot of Owen looking at her. In this shot his hand is around his beer bottle holding it at the base.
