The world's first-ever 100% complete t-rex skeleton has been found, and the beast was locked in a duel to the death with a triceratops.
The remains were discovered in 2006, SWNS reports, but they have only been seen by a select few people over the past few years... until now.
The two dinosaurs, who have been dubbed the "Dueling Dinosaurs", have been preserved in what's known as a predator-prey encounter that involved them fighting to the death.
The importance of the discovery is emphasized by experts in the video below:Professional fossil hunters - a cattle rancher cowboy and two friends - found the dinosaurs entombed in sediment in Montana.
The quality of the skeletons is so good that their body outlines, skin impressions, and injuries - which include tyrannosaur teeth stuck in the triceratops body - are all still visible, despite the remains being 67 million years old.
The remains will now be available for the public to see after they were bought for an undisclosed sum by the Friends of the North Carolina Museum of Natural Sciences, who have donated them to the North Carolina Museum of Natural Sciences.
The museum is scheduled to begin building its exhibition of the remains in 2021, and these pictures have been released to mark the announcement.
It has been described as "one of the most important paleontological discoveries of our time".
Dr. Lindsay Zanno, head of paleontology at the museum, said: "We have not yet studied this specimen; it is a scientific frontier.
"The preservation is phenomenal, and we plan to use every technological innovation available to reveal new information on the biology of the T. rex and Triceratops.
"This fossil will forever change our view of the world's two favorite dinosaurs."
Dr. Eric Dorfman, director and CEO of the museum added: "The museum is thrilled to have the unique opportunity to house and research one of the most important paleontological discoveries of our time.
"Not only are we able to uncover unknown details of these animals' anatomy and behavior, but our new dedicated facility and educational programs will allow us to engage with audiences locally, across North Carolina, and worldwide."
The dinosaur bones are locked in their natural positions meaning that scientists have access to biological data that is typically lost as a result of the excavation and preparation processes.
