Jurassic Park is simply 'a dumb monster movie': Paleontologists slam Hollywood blockbuster for its glaring errors

It seems the scientists in Jurassic Park who messed around with dinosaur DNA still haven't learned their lesson.

In the latest film, Jurassic World, genetically-engineered dinosaurs make way for a terrifying genetically-engineered hybrid, named Indominus Rex.

Chaos ensues, with the trailer showing stars Chris Pratt and Bryce Dallas Howard battling to deal with the aftermath.

But while the plot has won over the public ahead of tomorrow's release, there's one group of people who are less than impressed; palaeontologists.

They argue that while the film has helped renew interest in dinosaurs, the plot provides a bizarre notion of how creatures lived in the Jurassic era.

Among the most cited inaccuracies are how T-Rex can't see you if you stay perfectly still, and how Velociraptors can open doors. 

But the scientist behind the film, Jack Horner, argues that many of these criticisms are based on opinion rather than fact.  

'I would disagree with that, Raptors can open doors, they certainly have the hands and arms,' he told DailyMail.com.

'We have no idea how smart the dinosaurs were..It's just their opinion. And most animals can't identify a human being if they've never seen one, and if you stand still.'

However, James Kirkland, who has been involved in the discovery of 20 dinosaurs, takes particular issue with the film's version of raptors.

He claims Jurassic World portrays them almost as cute creatures compared with the monster fossils that he's found during digs.

'They could have made it look like they had this attacking dinosaur that was bigger than T. rex, that would intimidate the large animals these things would have normally preyed on,' he told CBS NEWS.

'They could have seriously made these guys as intimidating. It actually could have been something you actually looked at as being somewhat nice.'

It's not just the raptors. A major source of disappointment for palaeontologists is the film's depiction of dinosaurs as leathery monsters.
