"We found the body of a man inside the leg of this dinosaur statue. It's an accidental death; there was no violence. This person got inside the statue's leg and got trapped," d'Esquadra said.
"It looks as though he was trying to retrieve a mobile phone, which he'd dropped. It looks like he entered the statue head first and couldn't get out."
The statue has now been removed.
The Stegosaurus, much loved by junior palaeontologists worldwide, is a four-legged, armoured dinosaur from the Late Jurassic age.
Known to be a herbivore in possession of a tiny brain, the Stegosaurus was first discovered in 1877.
Its famous plates have been the subject of intense debate in the palaeontology community, with suggestions made that they acted to lower the animal's body temperature or to intimidate foes or to attract mates.
