The tyrannosaurus rex, which was found buried in a sediment near the triceratops, is thought to have been at war with the dinosaur at the time of its death.
The first 100% completed T. rex ever found will soon be on display at a museum in North Carolina.
Nicknamed the “Dueling Dinosaurs”, the couple was saved together in a predator collision 67 million years ago.
Professionals say dinosaur body contours, skin prints and even injuries, such as T-Rex teeth stuck in Triceratops̵
The remains were first discovered in 2006 in Montana, USA by fossil hunters. So far, they have been seen by only a few dozen people.
It took years to retrieve the 14-ton skeletons and arrange for their purchase from the Natural History Museum of North Carolina for an undisclosed amount.
Most T. rex skeletons are kept by museums and private institutions.
Since then, the nonprofit has donated the fossils to the Museum of Natural Sciences in North Carolina, which is set to begin construction of a special exhibition next year.
Dueling dinosaurs, which have not yet been studied, have been described as “one of the most important paleontological discoveries of our time.”
Dr. Lindsay Zano, head of paleontology at the museum, said:
This fossil will forever change our view of the world’s two favorite dinosaurs. The conservation is phenomenal and we plan to use every available technological innovation to uncover new information about the biology of T. rex and Triceratops.
T. rex also has skin prints – fossilized remnants of skin surfaces – which are extremely rare.
The explanation for how the dinosaur was so well preserved may be due to the fact that it was found buried in the sediment from the hill of Montana.
Each bone is still in its natural position, which means that scientists will have access to biological data that is usually lost in the process of excavation and preparation.
The fossil hunters who originally discovered the dinosaurs are reported to have reached an agreement with the landowners.
But a legal battle quickly ensued over ownership of the skeletons, which are worth millions of dollars.
About 14 years later, in June this year, a U.S. court of appeals ruled that the fossils belonged to the landowners.
The “Duel Dinosaurs” were first auctioned in 2013 at Bonhams in New York, but no offer matched the $ 6 million reserve price (£ 4.5 million).
During years of negotiations, the fossil has been locked in laboratories or warehouses – until now.
