The trailer for the film was recently released, but people have already started to point out there are a few scientific issues visible in the short clip.
Firstly, there is this concern about the Big Bad having thumbs.
Which, as pointed out, is a worrying addition to a super-smart dinosaur.
We're convinced.
Then there were issues with the mosasaur's lack of a forked tongue.
As a result, this giant carnivorous reptile with rows and rows of razor-sharp teeth isn't remotely scary.
There was also this quibble with its back.
This bit. They're talking about this bit.
It's actually a scientific theory that was debated over many years, with National Geographic providing an in-depth explanation of the process by which the Tylosaurus, a subfamily of mosasaur, lost its fin.
Then the entomologists got involved.
Mosquito on the left, crane fly on the right.
This is probably a good time to point out that the whole mosquito thing wouldn't work anyway.
Especially given this oft-forgotten plot point from the first film.
Then it was on to the feather problem, as in recent years it has become increasingly clear that dinosaurs had feathers.
Fossils such as this one of a Sinosauropteryx provide evidence of non-avian dinosaurs also having feathers of a sort.
Scenes like this probably would look a tiny bit daft with feathers though, so ¯\_(ツ)_/¯
The scientists are still pretty excited about the movie, despite its possible flaws.
Of course, this is probably still the biggest question.
