Children love to obsesses over things.
Football, trains, Lego, Peppa Pig!
And if your little one has a love of Jurassic Park , is like Ross from Friends or knows that a triceratops was from the late Cretaceous period you could have a genius on you hands.
The study, which is not new but has recently resurfaced online, found that children who develop obsessive interests, in things such as dinosaurs , will go on to experience a number of benefits.
Where to take the kids in Wales if they are obsessed with dinosaurs
The Mirror reported that these include enhanced perseverance, improved attention and an increase in skills of complex thinking such as processing information.
As well as this, the way in which a child studies dinosaurs was also shown to help them develop strategies to tackle problems throughout life.
This may sound like great news if your child is passionate about dinosaurs, but don't be too downhearted if their interest in the subject disappears.
Most childhood obsessions fade quickly, with only around 20% of children retaining their interests until they start school age five or six.
Wales has been a the site of several dino discoveries. You can see a map of all of them here:
And a love of dinosaurs isn't the only bizarre signifier of higher intelligence in children - not being able to sleep through the night is also supposed to be an indicator of how clever a child is.
Professor Peter Fleming, who works on infant health and developmental psychology at the university of Bristol, has claimed babies who don't sleep all night are potentially smarter than those who love snoozing.
He suggested that not sleeping through the night and high levels of intellectual achievement might in fact be correlated.
"Human infants are not designed to sleep for long periods," he explained. "It's not good for them and there is absolutely no evidence whatsoever that there is any benefit to anybody from having a child that sleeps longer and consistently," he said.
"That's not perhaps what most parents would like to hear."
