The bones are out there somewhere.
It just takes a farmer to come across them.
When he does, a paleontologist swoops in with a tape measures and declares: "This thigh bone is bigger than me."
This is what seems to have happened in the Argentinian desert near the town of La Flecha.
Once the farmer had made his discovery, a team of paleontologists made their examinations, and now, as the BBC reports, they believe they've found the biggest dinosaur ever discovered.
"Given the size of these bones, which surpass any of the previously known giant animals, the new dinosaur is the largest animal known that walked on Earth," the researchers told the BBC's Natural History Unit.
The fossilized thigh bone, along with an arm bone, indicate a creature that wasn't merely 130 feet long but also 60 feet tall. Which leads our paleo pals to the conclusion that these are the remains of a heretofore unknown variety of titanosaur, a type of very large, herbivorous dino with a small head and humungous body. This new specimen, the researchers say, was seven tons heavier than the previous record holder.
Some experts, though, aren't yet convinced that these creatures were quite so titanic, as they would prefer to see whole skeletons in order to assess the true size.
In total, the team has found 150 bones, which they say came from seven different specimens of the newly identified titano variety. The bones are said to be in excellent condition.
In the case of this new discovery, the paleontologists haven't decided on what to call their new big baby. They do, however, have a principle behind the naming process.
They told the BBC: "It will be named describing its magnificence and in honor to both the region and the farm owners who alerted us about the discovery."
The previous record holder was the imaginatively named Argentinosaurus.
