Jurassic World: Fallen Kingdom - 20 WTF Moments
15. All The Dead Dinosaurs

The conclusion of the eruption sequence is actually legitimately upsetting and perhaps the single moment in the movie that musters some genuine emotion (beyond frustration, anyway).
The poor dinosaurs find themselves forced to leap off a cliff edge when the volcano's pyroclastic flow consumes the mainland. As Claire and Franklin splash into the water in their Gyrosphere, we can see countless dinosaurs around them struggling to keep above water, with most of them clearly drowning.
Things go one step more disturbing when the gang manages to sneak onto Lockwood's boat, as in their departing moments they witness a Brachiosaurus calling out to them shortly before being consumed by the volcano. It's horrifying, and one of the movie's few legitimately great moments.
