The Supersaurus dinosaur, which roamed the United States millions of years ago, may win the title of longest dinosaur in the world.
The dinosaur is between 128 and 137 feet, according to research presented at the Society of Vertebrate Paleontology's annual conference, Live Science reports. That means its longer than a Boeing 737 aircraft and a blue whale.
Think of a 13-story building turned sideways. That's how long this dinosaur was. Or for another perspective, this Supersaurus was roughly three times longer than an average school bus.
Don't fear, while they could probably crush you, these dinosaurs were herbivores and lived in the Early Cretaceous period 154 to 142 million years ago, according to the Natural History Museum.

However, researchers acknowledge that it might not be the longest dinosaur in the world. Dinosaur bones are often found in fragments, meaning many dinosaurs may not have all their bones discovered, making it impossible to accurately guess their height, said Brian Curtice, a paleontologist at the Arizona Museum of Natural History who is spearheading the research.
The Supersaurus dinosaur was actually involved in a mix-up with other fossils that scientists recently fixed. Combined with those misplaced bones was a new set of excavated fossils in the dinosaur's final resting spot, which helped construct a more complete picture of the dinosaur's length, Live Science reported.
Excavation of the site began as early as 1972, when paleontologists discovered an enormous mound of bones in Colorado. Curtice describes the finding as a "bone salad," and scientists had originally believed that the bones of the Supersaurus actually belonged to three separate dinosaurs.
The research, which was presented on Nov. 5, is not yet published in a peer-reviewed journal.
